Carbon Compounds Quotes

In the visible world, the Milky Way is a tiny fragment; within this fragment, the solar system is an infinitesimal speck, and of this speck our planet is a microscopic dot. On this dot, tiny lumps of impure carbon and water, of complicated structure, with somewhat unusual physical and chemical properties, crawl about for a few years, until they are dissolved again into the elements of which they are compounded.

Imagine trying to live in a world dominated by dihydrogen oxide, a compound that has no taste or smell and is so variable in its properties that it is generally benign but at other times swiftly lethal. Depending on its state, it can scald you or freeze you. In the presence of certain organic molecules it can form carbonic acids so nasty that they can strip the leaves from trees and eat the faces off statuary. In bulk, when agitated, it can strike with a fury that no human edifice could withstand. Even for those who have learned to live with it, it is an often murderous substance. We call it water.

Whatever the nature of organizing relations may be,' J. Needham wrote in 1932, 'they form the central problem of biology, and biology will be fruitful in the future only if this is recognized. The hierarchy of relations, from the molecular structure of carbon compounds to the equilibrium of species and ecological wholes, will perhaps be the leading idea of the future.

Nature devours us. Icy winds and rain and salt and snow erode us, decompose us, reduce us to molecules, carbon compounds; the covalent bonds between the carbon and hydrogen atoms break. Our atoms mingle with the brown grains of sand on the only small strip of beach on White Island.

Originally, the atoms of carbon from which we’re made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life—the carbohydrates, amino acids, proteins, and lipids—is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.

Men presumably always have looked at flowers and been moved by their beauty and their smell: but only since the last century has it been possible to take a flower in your hand and know that you have between your fingers a complex association of organic compounds containing carbon, hydrogen, oxygen, nitrogen, phosphorus, and a great many other elements, in a complex structure of cells, all of which have evolved from a single cell; and to know something of the internal structure of these cells, and the processes by which they evolved, and the genetic process by which this flower was begun, and will produce other flowers; to know in detail how the light from it is reflected to your eye; and to know the details of those workings of your eye, and your nose, and your neurophysiological system, which enable you to see and smell and touch the flower. These inexhaustible and almost incredible realities which are all around us and within us are recent discoveries which are still being explored, while similar new discoveries continue to be made; and we have before us an endless vista of such new possibilities stretching into the future, all of it beyond man’s wildest dreams until almost the age we ourselves are living in. Popper’s ever present and vivid sense of this, and of the fact that every discovering opens up new problems for us, informs his theoretical methodology. He knows that our ignorance grows with our knowledge, and that we shall therefore always have more questions than answers.

Dreadful as all these processes may seem, they are only the resolution of certain carbon-based compounds into certain other carbon-based compounds. Carbon is the element of life and death. We share it with diamonds and dandelions, with kerosene an kelp. While we may wrinkle our noses at some of its manifestations, we ought also to remember that this element comes to us from the stars, which wheel over us forever in silent, glittering array, pure fires obeying celestial laws.

The problem of the origin of life is, at bottom, a problem in organic chemistry—the chemistry of carbon compounds—but organic chemistry within an unusual framework. Living things, as we shall see, are specified in detail at the level of atoms and molecules, with incredible delicacy and precision. At the beginning it must have been molecules that evolved to form the first living system. Because life started on earth such a long time ago—perhaps as much as four billion years ago—it is very difficult for us to discover what the first living things were like. All living things on earth, without exception, are based on organic chemistry, and such chemicals are usually not stable over very long periods of time at the range of temperatures which exist on the earth's surface. The constant buffeting of thermal motion over hundreds of millions of years eventually disrupts the strong chemical bonds which hold the atoms of an organic molecule firmly together over shorter periods; over our own lifetime, for example. For this reason it is almost impossible to find "molecular fossils" from these very early times.

Ocean Acidification is sometimes referred to as Global Warming's Equally Evil Twin. The irony is intentional and fair enough as far as it goes... No single mechanism explains all the mass extinctions in the record and yet changes in ocean chemistry seem to be a pretty good predictor. Ocean Acidification played a role in at least 2 of the Big Five Extinctions: the End-Permian and the End-Triassic. And quite possibly it was a major factor in a third, the End-Cretaceous. ...Why is ocean acidification so dangerous? The question is tough to answer only because the list of reasons is so long. Depending on how tightly organisms are able to regulate their internal chemistry, acidification may affect such basic processes as metabolism, enzyme activity, and protein function. Because it will change the makeup of microbial communities, it will alter the availability of key nutrients, like iron and nitrogen. For similar reasons, it will change the amount of light that passes through the water, and for somewhat different reasons, it will alter the way sound propagates. (In general, acidification is expected to make the seas noisier.) It seems likely to promote the growth of toxic algae. It will impact photosynthesis—many plant species are apt to benefit from elevated CO2 levels—and it will alter the compounds formed by dissolved metals, in some cases in ways that could be poisonous. Of the myriad possible impacts, probably the most significant involves the group of creatures known as calcifiers. (The term calcifier applies to any organism that builds a shell or external skeleton or, in the case of plants, a kind of internal scaffolding out of the mineral calcium carbonate.)... Ocean acidification increases the cost of calcification by reducing the number of carbonate ions available to organisms that build shells or exoskeletons. Imagine trying to build a house while someone keeps stealing your bricks. The more acidified the water, the greater the energy that’s required to complete the necessary steps. At a certain point, the water becomes positively corrosive, and solid calcium carbonate begins to dissolve. This is why the limpets that wander too close to the vents at Castello Aragonese end up with holes in their shells. According to geologists who work in the area, the vents have been spewing carbon dioxide for at least several hundred years, maybe longer. Any mussel or barnacle or keel worm that can adapt to lower pH in a time frame of centuries presumably already would have done so. “You give them generations on generations to survive in these conditions, and yet they’re not there,” Hall-Spencer observed.

All matter is made of atoms. There are more than 100 types of atoms, corresponding to the same number of elements. Examples of elements are iron, oxygen, calcium, chlorine, carbon, sodium and hydrogen. Most matter consists not of pure elements but of compounds: two or more atoms of various elements bonded together, as in calcium carbonate, sodium chloride, carbon monoxide. The binding of atoms into compounds is mediated by electrons, which are tiny particles orbiting (a metaphor to help us understand their real behaviour, which is much stranger) the central nucleus of each atom. A nucleus is huge compared to an electron but tiny compared to an electron’s orbit. Your hand, consisting mostly of empty space, meets hard resistance when it strikes a block of iron, also consisting mostly of empty space, because forces associated with the atoms in the two solids interact in such a way as to prevent them passing through each other. Consequently iron and stone seem solid to us because our brains most usefully serve us by constructing an illusion of solidity. It has long been understood that a compound can be separated into its component parts, and recombined to make the same or a different compound with the emission or consumption of energy. Such easy-come easy-go interactions between atoms constitute chemistry. But, until the

WE’RE GOOD AT WRONG SPOTTING If you’ve ever received feedback at work—or had an in-law—you are familiar with the many shapes and sizes of wrong: It’s 2 + 2 = 5 wrong: It is literally incorrect. I could not have been rude at that meeting because I was not at that meeting. And my name is not Mike. It’s different-planet wrong: Somewhere in the universe there may exist a carbon-based life form that would have taken offense at my e-mail, but here on Earth everyone knows it was a joke. It used to be right: Your critique of my marketing plan is based on how marketing worked when you were coming up. Before the Internet. And electricity. It’s right according to the wrong people: Some see me that way, but next time, talk to at least one person who is not on my Personal Enemies List. Your context is wrong: I do yell at my assistant. And he yells at me. That’s how our relationship works—key word being “works.” It’s right for you, but wrong for me: We have different body types. Armani suits flatter you. Hoodies flatter me. The feedback is right, but not right now: It’s true that I could lose a few pounds—which I will do as soon as the quintuplets are out of the house. Anyway, it’s unhelpful: Telling me to be a better mentor isn’t helping me to be a better mentor. What kind of mentor are you anyway? Why is wrong spotting so easy? Because there’s almost always something wrong—something the feedback giver is overlooking, shortchanging, or misunderstanding. About you, about the situation, about the constraints you’re under. And givers compound the problem by delivering feedback that is vague, making it easy for us to overlook, shortchange, and misunderstand what they are saying. But in the end, wrong spotting not only defeats wrong feedback, it defeats learning.

Incandescent carbon particles, by the tens of millions, leap free of the log and wave like banners, as flame. Several hundred significantly different chemical reactions are now going on. For example, a carbon atom and four hydrogen atoms, coming out of the breaking cellulose, may lock together and form methane, natural gas. The methane, burning (combining with oxygen), turns into carbon dioxide and water, which also go up the flue. If two carbon atoms happen to come out of the wood with six hydrogen atoms, they are, agglomerately, ethane, which bums to become, also, carbon dioxide and water. Three carbons and eight hydrogens form propane, and propane is there, too, in the fire. Four carbons and ten hydrogens—butane. Five carbons … pentane. Six … hexane. Seven … heptane. Eight carbons and eighteen hydrogens—octane. All these compounds come away in the breaking of the cellulose molecule, and burn, and go up the chimney as carbon dioxide and water. Pentane, hexane, heptane, and octane have a collective name. Logs burning in a fireplace are making and burning gasoline.

Methylation works by the use of a chemical compound, in the shape of three-leaf clovers made up of hydrogen and carbon,

It seems likely that the bonding versatility of carbon was a major factor in the selection of carbon compounds for the molecular machinery of cells during the origin and evolution of living organisms

Created in the liver from acetyl-CoA, the ketone bodies, β-hydroxybutyrate and acetoacetate, are four carbon compounds. They constitute a way for acetyl-CoA units (from fat) to be transported from the liver to other tissues where they are turned back into acetyl-CoA and used for energy. The selective advantage is that it takes the pressure off protein having to provide glucose under extreme conditions.

So the coffee came and I tasted it—a hot, foul, acidic, dual-carbon compound liquid—and I spat it out all over her. A major breach of human etiquette: apparently, I was meant to swallow

Carlton Church Warning - Nuclear Fraud Scheme North Korea has been producing different nuclear weapons since last year. They have sent warning on the neighboring countries about their plan for a nuclear test. Not just South Korea, but other countries like China, U.S., and Japan have stated their complaints. Even the United Nations has been alarmed by North Korea’s move. During the last period of World War, a bomb has been used to attack Japan. Happened on 6th of August 1945, Enola Gay dropped an atomic bomb just 10 kilometers away from Tokyo. This is why people and organizations like Carlton Church who’s against the use of nuclear power for production of armory in war. Many protested that it is a threat to mankind and environment. Groups who are in favor of the nuclear use explained its advantage. They say it can be helpful in generating electricity that can be used for residential and commercial purposes. They also expound how it is better to use than coal mining as it is “less harmful to the environment.” Nuclear Use: Good or Bad? Groups who are against the use of nuclear reactor and weapons try to persuade people about its catastrophic result to the environment and humankind. If such facility will be used to create weapons, there is a possibility for another world war. But the pro-nuclear groups discuss the good effects that can be gained from it. They give details on how greenhouse gas effect of coal-burning can emit huge amounts of greenhouse gases and other pollutants such as sulfur dioxide nitrogen oxide, and toxic compounds of mercury to the atmosphere every year. Burning coal can produce a kilowatt-hour of electricity but it also amounts to over two pounds of carbon dioxide emissions. They also added that the amount of carbon dioxide it produces contributes to climate change. Sulfur dioxide may cause the formation of acid rain and nitrogen oxide, if combined with VOCs, will form smog. Nuclear power plants do not emit harmful pollutants or other toxic gases. Generating energy from nuclear involves intricate process, but as a result, it produces heat. These plants have cooling towers that release water vapor. If the facility has been properly managed it may not contribute disturbance in the atmosphere. It may sound better to use compared to coal. But studies have shown that the vapor that came from nuclear plants have an effect to some coastal plants. The heated water that was released goes back to lakes and seas, and then the heat will eventually diffuse into surface warming. As a result of the increased water temperature on the ocean bodies, it changes the way carbon dioxide is transferred within the air. In effect, major shifts in weather patterns such as hurricanes may occur. It does not stop there. The nuclear power plant produces radioactive waste, which amounts to 20 metric tons yearly. Exposure to high-level radiation is extremely harmful and fatal to human and animals. The waste material must be stored carefully in remote locations for many years. Carlton Church and other anti-nuclear groups persuade the public to initiate banning of the manufacturing of nuclear products and give warnings about its health hazards and environmental effects.

The combined activities of our enormous population are already producing breathtaking effects. Our planet is only 12,700 kilometers in diameter—about three times the distance between New York and Los Angeles—and we can easily travel halfway around it in less than a day. We have turned much of its land surface into a patchwork of cities, industrial parks, farms, and rangeland. We have laid on this land a web of roads, canals, and pipelines. We have dug out of it hundreds of billions of tons of material, moved this material around, processed it, and dumped it. Our factory ships and trawlers crisscross the world’s oceans to exploit every valuable fishery. Our planes and satellites weave themselves around its sphere. We are moving so much rock and dirt, blocking and diverting so many rivers, converting so many forests to cropland, releasing such huge quantities of heavy metals and organic chemicals into air and water, and generating so much energy, carbon dioxide, methane, and nitrogen compounds that we are perturbing the deepest dynamics of our global ecosystems. Between one-third and one-half of the planet’s land area has been fundamentally transformed by our actions: row-crop agriculture, cities, and industrial areas occupy 10 to 15 percent of Earth’s land surface; 6 to 8 percent has been converted to pasture; and an area the size of France is now submerged under artificial reservoirs. We have driven to extinction a quarter of all bird species. We use more than half of all accessible fresh water. In regions of major human activity, large rivers typically carry three times as much sediment as they did in pre-human times, while small rivers carry eight times the sediment. Along the world’s tropical and subtropical coastlines, our activities—especially the construction of cities, industries, and aquaculture pens—have changed or destroyed 50 percent of mangrove ecosystems, which are vital to the health of coastal fisheries. And about two-thirds of the world’s marine fisheries are either overexploited, depleted, or at their limit of exploitation. The decline of global fish stocks has followed a predictable pattern: like roving predators, we have shifted from one major stock to another as each has reached its maximum productivity and then begun to decline.30

Living organisms are constructed, for the most part, from compounds of carbon and hydrogen. Carbon is critical because of its astonishing flexibility. Add hydrogen, nitrogen, oxygen, phosphorus, and sulfur and we can account for 99 percent of the dry weight of all living organisms.

Wealth is where history shows up in your wallet, where your financial freedom is determined by compounding interest on decisions made long before you were born. That is why the Black-white wealth gap is growing despite gains in Black education and earnings, and why the typical Black household owns only $17,600 in assets. Still, having little to no intergenerational wealth and facing massive systemic barriers, descendants of a stolen people have given America the touch-tone telephone, the carbon filament in the lightbulb, the gas mask, the modern traffic light, blood banks, the gas furnace, open-heart surgery, and the mathematics to enable the moon landing. Just imagine the possibilities if—in addition to rebuilding the pathways for all aspirants to the American Dream—we gave millions more Black Americans the life-changing freedom that a modest amount of wealth affords. A 2020 Citigroup report calculated that “if racial gaps for Blacks had been closed 20 years ago, U.S. GDP could have benefitted by an estimated $16 trillion.

[This “wood-wide web” is an underground Internet through which water, carbon, nitrogen, phosphorus, and even defense compounds are exchanged

Every chemical compound, according to Engels, comes into existence only at a certain time in the development of the universe when the conditions are appropriate for it; and when it does come into existence it manifests this by entering into its characteristic relations. Neither carbon compounds or proteins are ideal forms, but are themselves witnesses of the conditions on a cooling planet. It is here that occurs his celebrated remark that life is the mode of existence of proteins.

Octane (C8H18) is one of the alkanes (hydrocarbons with the general formula CnH2n + 2) that form anywhere between 10 to 40 percent of light crude oils, and one of its isomers (compounds with the same number of carbon and hydrogen atoms but with a different molecular structure),

Readily available stones and wood can be turned into only a limited range of tools, machines, and structures. That is why the third category of inventions, new materials, has been an obvious marker of civilization’s progress, from the age of stone and wood to the era of metals, mixtures, and compounds. Inventions in the third category began with bronze, proceeded to iron and steel (iron’s largely decarbonized alloy), and now include aluminum and a dozen other common metals, as well as glass, cement (an aggregate of materials), and, starting in the late nineteenth century, a still-expanding variety of plastics and—the most recent addition—carbon-based composites, light yet stronger than steel.

The IPCC report explains that every single metric ton of carbon dioxide we prevent from entering the atmosphere lessens the severity of the impacts we bake into the system. Our assessment meticulously describes how every fraction of a degree of warming matters—the scale and severity of impacts begin to compound and cascade with higher levels of warming.

How? Next time you’re in a forest, dig into the duff, and you’re bound to find white, cobwebby threads attached to roots. These are the underground parts of special fungi that deliver phosphorus to trees in return for carbon. Textbooks once described the exchange as exclusive, one tree to one fungus, until the data begged to differ. Simard’s work was among the first to prove that fungi branch out from the roots of one tree to connect dozens of trees and shrubs and herbs—not only relatives but entirely different species. [This “wood-wide web” is an underground Internet through which water, carbon, nitrogen, phosphorus, and even defense compounds are exchanged.] When a pest troubles one tree, its alarm chemicals travel via fungi to the other members of the network, giving them time to beef up their defenses. Thanks to researchers like Simard, foresters are now encouraged to leave birch and large hub trees in the forest to give seedlings a fast connection to the network.

Sodium bicarbonate is a chemical compound with the chemical formula NaHCO3. It is one of the sodium salts. It has anti acid properties. It is also used as baking powder. It is soluble in water. It is a white solid crystalline powder. It has a slightly alkaline taste reminiscent of sodium carbonate. The baking powder used to rise the dough is usually a combination of Sodium bicarbonate (NaHCO3), dry acid (H+) and cornstarch. Sodium bicarbonate is colloquially known as carbonate. In the article below, the word carbonate will be used instead of sodium bicarbonate. Under the influence of temperature (50 °C and above), water (H2O) and acid, the carbonate in baking soda splits into several components. During this process, carbon dioxide (CO2) gas is released, gas bubbles are formed and thus the dough expands.

The other theory argues that replication based on nucleic acids (RNA and/or DNA) came after biological entities could support metabolism. Günter Wächtershäuser proposed a version of this metabolism-first theory in which hot water from volcanoes flowed over mineral-rich rocks to ignite (catalyze) chemical reactions that fused simple carbon-based compounds into larger ones. While catalytic enzymes, which are proteins, did not yet exist, minerals, such as those in rocks, can and do function as prebiotic catalysts for chemical reactions. According to this theory, a key step occurred when, through a series of these prebiotic reactions, the circle was closed by the regeneration of the original compound. Through such a process, complex biological molecules (proteins, nucleotides, lipids, and carbohydrates) could be made, forming the basis of simple protocells that made energy and replicated.

Of the carbon that is found in soils—which, remarkably, amounts to twice the amount of carbon found in plants and the atmosphere combined—a substantial proportion is bound up in tough organic compounds produced by mycorrhizal fungi.

It is as if chemists called any compound that contained carbon—from diamond to methane to methamphetamine—carbon.

Life is easy to identify but remarkably difficult to define. Too tight a definition excludes what looks like life and too loose captures too much. The capacity to self-replicate is a component of the definition, but not without its problems, as a mule is alive but sterile, and computer software can replicate itself, but we do not, in all honesty, think of it as being alive. It might be tempting to ascribe livingness to an entity that has emerged by evolution, but that would exclude the first living entity and any that we might synthesize from scratch in future. Organisms are organized structures; but so is an integrated circuit. Organisms are organized structures built and sustained by the flux of energy through their interiors and its dissipation into the surroundings; but so are the patterns of convection that can arise in heated liquids and, indeed, the atmosphere, to give rise to the weather: think tornado and hurricane. All known organisms are built from compounds of carbon; but if we succeeded in building a replicating, conscious, self-sustaining, energy-dissipating entity from silicon, would we deny that it was alive? Is a virus alive?

Regardless of where they strike, large asteroids would boil seas, fill the air with dust and acidic compounds, and perhaps induce carbon dioxide to cook off out of the rocks and into the air, triggering a strong greenhouse effect, all of which in turn would change the world’s climate faster than living things could adjust to. Giant impactors could create enormous waves in the ocean and in the atmosphere that could upset weather patterns around the world for extended periods. Perhaps asteroids have also helped unleash Earth’s internal heat and caused subsequent volcanism.

By 1870 there were competing formulae, and luminous paints were selling briskly. Most used strontium carbonate or strontium thiosulphate. It had been found, probably accidentally, that strontium compounds would seem to store sunlight and would then give it back after the sun went down. We now know this phenomenon as a “forbidden energy-state transition” in a singlet ground-state electron orbital. The strontium, like everything else, absorbs and then returns a light photon that hits it, but in this case the return is delayed. The strontium atom, excited to a higher energy state by the absorption of light, “decays,” as if it were radioactive, reflecting the light back with a half-life of about 25 minutes. After four hours of glowing, the strontium compound needs to be re-charged with light.

They drive planetary cycles of carbon, nitrogen, sulphur and phosphorus, by converting these elements into compounds that can be used by animals and plants and then returning them to the world by decomposing organic bodies. They were the first organisms to make their own food, by harnessing the sun’s energy in a process called photosynthesis. They released oxygen as a waste product, pumping out so much of the gas that they permanently changed the atmosphere of our planet. It is thanks to them that we live in an oxygenated world. Even now, the photosynthetic bacteria in the oceans produce the oxygen in half the breaths you take, and they lock away an equal amount of carbon dioxide.
