Zitat des Tages über Proteine / Proteins:
A boxer's diet should be low in fat and high in proteins and sugar. Therefore you should eat plenty of lean meat, milk, leafy vegetables, and fresh fruit and ice cream for sugar.
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.
The body cannot produce enzymes in perfect combinations to metabolize your foods as completely as the food enzymes created by nature do. This results in partially digested fats, proteins, and starches that can clog your body's intestinal tract and arteries.
Owing to the difficulty of dealing with substances of high molecular weight we are still a long way from having determined the chemical characteristics and the constitution of proteins, which are regarded as the principal con-stituents of living organisms.
As I get older and maybe a little bit wiser, you realize how much stuff affects your body and what it can do. Cutting out carbs and sweets and trying to eat just proteins and fruits and stuff like that, more natural stuff, is what I have found has had the biggest impact on me.
Brain cells are normally not sensitive to light. So by introducing light-sensitive proteins into specific types of neurons, we can now selectively control that specific type of neuron by shining light in the brain.
I do eat what I want. I love meat - I'm Cuban: I grew up eating meat, platanos, and arroz con pollo. I don't believe in starving yourself, but sometimes I do cleanses and diets to prepare for a role. I choose a lot of greens, proteins, and fats, and I like to be really active.
As can be seen even by this limited number of examples proteins carry out amazingly diverse functions.
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.
During the decade following the discovery of the double-helical structure of DNA, the problem of translation - namely, how genetic information is used to synthesize proteins - was a central topic in molecular biology.
The basic structure of proteins is quite simple: they are formed by hooking together in a chain discrete subunits called amino acids.
Agriculture as we know it needs to disappear. We can design better and healthier proteins than we get from nature.
A meringue is really nothing but a foam. And what is a foam after all, but a big collection of bubbles? And what's a bubble? It's basically a very flimsy little latticework of proteins draped with water. We add sugar to this structure, which strengthens it. But things can, and do, go wrong.
My interest in protein breakdown as a research problem began in l955 at about the time I joined the Biochemistry Department of Yale University. It was known that proteins break down intracellularly in the mature animal.
Proteins are the machinery of living tissue that builds the structures and carries out the chemical reactions necessary for life.
Space and time, not proteins and neurons, hold the answer to the problem of consciousness. When we consider the nerve impulses entering the brain, we realize that they are not woven together automatically, any more than the information is inside a computer.
And of course, identifying all human genes and proteins will have great medical significance.
A virus is not just DNA; a virus is also packaged up, covered over with a series of proteins in a nice, elegant, well-compacted form.
I'm typically a 'just drink water' kind of guy. I was a bodybuilder in high school, so I used to - food to me was, 'there are this many grams of carbohydrates and proteins, and I need these micronutrients in order to grow and be fit,' and I ate in order to live and not live in order to eat, and I think most people are the opposite.
One of the major lessons in all of biochemistry, cell biology and molecular medicine is that when proteins operate at the sub cellular level, they behave in a certain way as if they're mechanical machinery.
I'm a very, very healthy eater, so it's proteins, greens, proteins, and more greens - and lots of water.
It's nice to be able to look at one protein, but life is driven by the interactions between proteins, so it's really essential to be able to see multiple proteins at a time to understand these interactions.
For a decade, I had been studying a transparent worm, the C. elegans. I immediately thought, if you could put the G.F.P. gene into C. elegans, you'd then be able to see biological processes in live animals. Until then, we had to kill them and prepare their tissues chemically to visualize proteins or active genes within cells.
I realized that I didn't need nearly as many calories as I'd grown accustomed to. I ate 100 to 200 calories every two hours or so, consumed healthy proteins (yogurt, lean meat, turkey jerky), and drank a gallon of water a day. And as my weight dropped, my energy soared.
I have a chef who makes sure that I'm getting the right amounts of carbs, proteins and fats throughout the day to keep me at my max performance level.
There are over 7,000 different types of proteins in typical eukaryotic cells; the total number depends on the cell class and function.
Science is the one culture that's truly global - protons, proteins and Pythagoras's Theorem are the same from China to Peru. It should transcend all barriers of nationality. It should straddle all faiths, too.
I eat healthy and don't go by a diet chart. The breakfast is usually heavy, complemented with short frequent meals. My dinner is high on proteins and low on carbohydrates.
Science is a part of culture. Indeed, it is the only truly global culture because protons and proteins are the same all over the world, and it's the one culture we can all share.
