A Quote by Isaac Asimov

You see, proteins, as I probably needn't tell you, are immensely complicated groupings of amino acids and certain other specialized compounds, arranged in intricate three-dimensional patterns that are as unstable as sunbeams on a cloudy day. It is this instability that is life, since it is forever changing its position in an effort to maintain its identity--in the manner of a long rod balanced on an acrobat's nose.
Genes are effectively one-dimensional. If you write down the sequence of A, C, G and T, that's kind of what you need to know about that gene. But proteins are three-dimensional. They have to be because we are three-dimensional, and we're made of those proteins. Otherwise we'd all sort of be linear, unimaginably weird creatures.
Social reality is so complicated that, once you join one team or the other, you become specialized in detecting certain patterns, but you become blind to other patterns.
The basic structure of proteins is quite simple: they are formed by hooking together in a chain discrete subunits called amino acids.
I just don't see how it is possible to be a vegetarian or vegan when you break your body down so much. You have to recover. You need those proteins and proper amino acids, like leucine, which only really comes from animal fats.
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.
DNA is a code of four letters; proteins are made up of amino acids which come in 20 forms. So the ribosome is a very clever machine that reads one language and operates in another.
The nucleic acids, as constituents of living organisms, are comparable In importance to proteins. There is evidence that they are Involved In the processes of cell division and growth, that they participate In the transmission of hereditary characters, and that they are important constituents of viruses. An understanding of the molecular structure of the nucleic acids should be of value In the effort to understand the fundamental phenomena of life.
Few scientists acquainted with the chemistry of biological systems at the molecular level can avoid being inspired. Evolution has produced chemical compounds exquisitely organized to accomplish the most complicated and delicate of tasks. Many organic chemists viewing crystal structures of enzyme systems or nucleic acids and knowing the marvels of specificity of the immune systems must dream of designing and synthesizing simpler organic compounds that imitate working features of these naturally occurring compounds.
It is, I believe, justifiable to make the generalization that anything an organic chemist can synthesize can be made without him. All he does is increase the probability that given reactions will 'go.' So it is quite reasonable to assume that given sufficient time and proper conditions, nucleotides, amino acids, proteins, and nucleic acids will arise by reactions that, though less probable, are as inevitable as those by which the organic chemist fulfills his predictions. So why not self-duplicating virus-like systems capable of further evolution?
Organic compounds exist in which a hydrogen atom, joined to the carbon, acquires acid properties as a result of the proximity of certain functional groupings.
Since I found that one could make a case shadow from a three-dimensional thing, any object whatsoever - just as the projecting of the sun on the earth makes two dimensions - I thought that by simple intellectual analogy, the fourth dimension could project an object of three dimensions, or, to put it another way, any three-dimensional object, which we see dispassionately, is a projection of something four-dimensional, something we are not familiar with.
I usually have about 16 pills a day of various descriptions - I also have minerals from Salt Lake City and amino acids that get sent to me from Australia.
When you have Candidate A saying the sky is blue, and Candidate B saying it's a cloudy day, I look outside and I see, well, it's a cloudy day. I should be able to tell my viewers, 'Candidate A is wrong, Candidate B is right,' and not have to say, 'Well, you decide.' Then it would be like I'm an idiot.
Back in the day I took a lot of supplements and tons of amino acids. Still do. But back then it was pretty unusual. That's how I got the nickname The Chemist.
I believe strongly that characters are five-dimensional, and they're complicated, and life is complicated, and people are complicated.
What happens in a play is determined to a certain extent by what I thought might be interesting to have happen before I invented the characters, before they started taking over what happened, because they are three-dimensional individuals, and I cannot tell them what to do. Once I give them their identity and their nature, they start writing the play.
