If the juices of the body were more chymically examined, especially by a naturalist, that knows the ways of making fixed bodies volatile, and volatile fixed, and knows the power of the open air in promoting the former of those operations; it is not improbable, that both many things relating to the nature of the humours, and to the ways of sweetening, actuating, and otherwise altering them, may be detected, and the importance of such discoveries may be discerned.

Love is a momentary upwelling of three tightly interwoven events: First, a sharing of one or more positive emotions between you and another; second, a synchrony between your and the other person’s biochemistry and behaviors; and third, a reflected motive to invest in each other’s well-being that brings mutual care
At lunch Francis [Crick] winged into the Eagle to tell everyone within hearing distance that we had found the secret of life.
I went to Duke University in the medical track. And then I decided I wanted to do something more creative, so I switched to biochemistry at Nebraska.
Beyond natural history Other biological sciences take up the study at other levels of organization: dissecting the individual into organs and tissues and seeing how these work together, as in physiology; reaching down still further to the level of cells, as in cytology; and reaching the final biological level with the study of living molecules and their interactions, as in biochemistry. No one of these levels can be considered as more important than any other.
The first entirely vital action, so termed because it is not effected outside the influence of life, consists in the creation of the glycogenic material in the living hepatic tissue. The second entirely chemical action, which can be effected outside the influence of life, consists in the transformation of the glycogenic material into sugar by means of a ferment.
A cell of a higher organism contains a thousand different substances, arranged in a complex system. This great organized system was not discovered by chemical or physical methods; they are inadequate to its refinement and delicacy and complexity.
Biology is far from understanding exactly how a single cell develops into a baby, but research suggests that human development can ultimately be explained in terms of biochemistry and molecular biology. Most scientists would make a similar statement about evolution.
It could be that at some earlier time, somewhere in the universe, a civilization evolved by probably some kind of Darwinian means to a very, very high level of technology- and designed a form of life that they seeded onto perhaps this planet. And I suppose it's possible that you might find evidence for that if you look at the details of biochemistry, molecular biology, you might find a signature of some sort of designer.
My origami creations, in accordance with the laws of nature, require the use of geometry, science, and physics. They also encompass religion, philosophy, and biochemistry. Overall, I want you to discover the joy of creation by your own handthe possibility of creation from paper is infinite.
BLINDSIGHT is fearless: a magnificent, darkly gleaming jewel of a book that hurdles the contradictions inherent in biochemistry, consciousness, and human hearts without breaking stride.
The mechanist is intimately convinced that a precise knowledge of the chemical constitution, structure, and properties of the various organelles of a cell will solve biological problems. This will come in a few centuries. For the time being, the biologist has to face such concepts as orienting forces or morphogenetic fields. Owing to the scarcity of chemical data and to the complexity of life, and despite the progresses of biochemistry, the biologist is still threatened with vertigo.
The biochemistry and biophysics are the notes required for life; they conspire, collectively, to generate the real unit of life, the organism. The intermediate level, the chords and tempos, has to do with how the biochemistry and biophysics are organized, arranged, played out in space and time to produce a creature who grows and divides and is.
Casein [the main protein found in dairy], in fact, is the most 'relevant' chemical carcinogen ever identified; its cancer-producin g effects occur in animals at consumption levels close to normal-striking ly unlike cancer-causing environmental chemicals that are fed to lab animals at a few hundred or even a few thousand times their normal levels of consumption.
Beadle believed that genetics were inseparable from chemistry-more precisely, biochemistry. They were, he said, "two doors leading to the same room."
If belief in evolution is a requirement to be a real scientist, it’s interesting to consider a quote from Dr. Marc Kirschner, founding chair of the Department of Systems Biology at Harvard Medical School: “In fact, over the last 100 years, almost all of biology has proceeded independent of evolution, except evolutionary biology itself. Molecular biology, biochemistry, physiology, have not taken evolution into account at all.
My main thesis will be that in the study of the intermediate processes of metabolism we have to deal not with complex substances which elude ordinary chemical methods, but with the simple substances undergoing comprehensible reactions... I intend also to emphasise the fact that it is not alone with the separation and identification of products from the animal that our present studies deal; but with their reactions in the body; with the dynamic side of biochemical phenomena.
To describe the overwhelming life of a tropical forest just in terms of inert biochemistry and DNA didn't seem to give a very full picture of the world.
I have never been disappointed upon asking microorganisms for whatever I wanted.
In marked contrast to the University of Wisconsin, Biochemistry was hardly visible at Stanford in 1945, consisting of only two professors in the chemistry department.
After taking my B.A. degree in 1939 I remained at the University for a further year to take an advanced course in Biochemistry, and surprised myself and my teachers by obtaining a first class examination result.
All experience is a drug experience. Whether it's mediated by our own [endogenous] drugs, or whether it's mediated by substances that we ingest that are found in plants, cognition, consciousness, the working of the brain, it's all a chemically mediated process. Life itself is a drug experience.
By the time I was 12 or 13, I was studying biochemistry textbooks.
It is now widely realized that nearly all the 'classical' problems of molecular biology have either been solved or will be solved in the next decade. The entry of large numbers of American and other biochemists into the field will ensure that all the chemical details of replication and transcription will be elucidated. Because of this, I have long felt that the future of molecular biology lies in the extension of research to other fields of biology, notably development and the nervous system.
Happier thoughts lead to essentially a happier biochemistry. A happier, healthier body. Negative thoughts and stress have been shown to seriously degrade the body and the functioning of the brain, because it's our thoughts and emotions that are continuously reassembling, reorganizing, re-creating our body
Now, a living organism is nothing but a wonderful machine endowed with the most marvellous properties and set going by means of the most complex and delicate mechanism.
There are living systems; there is no living "matter." No substance, no single molecule, extracted and isolated from a living being possess, of its own, the aforementioned paradoxical properties. They are present in living systems only; that is to say, nowhere below the level of the cell.
Don't be afraid of hard work. Nothing worthwhile comes easily. Don't let others discourage you or tell you that you can't do it. In my day I was told women didn't go into chemistry. I saw no reason why we couldn't.
By then, I was making the slow transition from classical biochemistry to molecular biology and becoming increasingly preoccupied with how genes act and how proteins are made.
Inborn errors of metabolism.
There are living systems; there is no'living matter'.
Love releases incredible energy that promotes the biochemistry of healing.
Happier thoughts lead to essentially a happier biochemistry. A happier, healthier body.
Molecular biology is essentially the practice of biochemistry without a license.
An unexpected benefit of my career in biochemistry has been travel.
I think if people are passionate about something, it could be real estate or biochemistry, and that spark gets turned on in them, everyone's beautiful in that zone.
The quality of your life is dependent upon the quality of the life of your cells. If the bloodstream is filled with waste products, the resulting environment does not promote a strong, vibrant, healthy cell life-nor a biochemistry capable of creating a balanced emotional life for an individual.
See yourself living in a new body. Hopeful = recovery. Happy = happier biochemistry. Stress degrades the bod.
If minds are wholly dependent on brains and brains on biochemistry, and biochemistry (in the long run) on the meaningless flux of the atoms, I cannot understand how the thought of those minds should have any more significance than the sound of the wind in the trees.
We know from astronomy that the universe had a beginning, from physics that the future is both open and unpredictable, from geology and paleontology that the whole of life has been a process of change and transformation. From biology we know that our tissues are not impenetrable reservoirs of vital magic, but a stunning matrix of complex wonders, ultimately explicable in terms of biochemistry and molecular biology. With such knowledge we can see, perhaps for the first time, why a Creator would have allowed our species to be fashioned by the process of evolution.
The world is too complicated in all parts and interconnections to be due to chance alone. I am convinced that the existence of life with all its order in each of its organisms is simply too well put together. Each part of a living thing depends on all its other parts to function. How does each part know? How is each part specified at conception? The more one learns of biochemistry the more unbelievable it becomes unless there is some type of organizing principle-an architect.
It's not how deep you go, it's how you go deep.
The conclusion of intelligent design flows naturally from the data itself - not from sacred books or sectarian beliefs. Inferring that biochemical systems were designed by an intelligent agent is a humdrum process that requires no new principles of logic or science. It comes simply from the hard work that biochemistry has done over the past forty years, combined with consideration of the way in which we reach conclusions of design every day.
Since Pawlow [Pavlov] and his pupils have succeeded in causing the secretion of saliva in the dog by means of optic and acoustic signals, it no longer seems strange to us that what the philosopher terms an 'idea' is a process which can cause chemical changes in the body.
All the more recent work on alkaptonuria has... strengthened the belief that the homogentisic acid excreted is derived from tyrosin, but why alkaptonuric individuals pass the benzene ring of their tyrosin unbroken and how and where the peculiar chemical change from tyrosin to homogentisic acid is brought about, remain unsolved problems.
It is one of the more striking generalizations of biochemistry - which surprisingly is hardly ever mentioned in the biochemical textbooks - that the twenty amino acids and the four bases, are, with minor reservations, the same throughout Nature.
In trying to evaluate Hopkins' unique contribution to biochemistry it may perhaps be said that he alone amongst his contemporaries succeeded in formulating the subject. Among others whose several achievements in their own fields may have surpassed his, no one has ever attempted to unify and correlate biochemical knowledge so as to form a comprehensible picture of the cell and its relation to life, reproduction and function.
As a progressive discipline [biochemistry] belongs to the present century. From the experimental physiologists of the last century it obtained a charter, and, from a few pioneers of its own, a promise of success; but for the furtherance of its essential aim that century left it but a small inheritance of facts and methods. By its essential or ultimate aim I myself mean an adequate and acceptable description of molecular dynamics in living cells and tissues.
But nothing ever put 'Hoppy' in the shade. No one could fail to recognize in the little figure... the authentic gold of intellectual inspiration, the Fundator et Primus Abbas of biochemistry in England.
In the 21st century our tastes buds, our brain chemistry, our biochemistry, our hormones and our kitchens have been hijacked by the food industry.
