Quotes About Proteins

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.

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.

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 soybean itself is a notably inauspicious staple food; it contains a whole assortment of antinutrients - compounds that actually block the body's absorption of vitamins and minerals, interfere with the hormonal system, and prevent the body from breaking down the proteins of the soy itself.

By all the laws of probability proteins shouldn't exist.

Proteins can't exist without DNA and DNA has no purpose without proteins. Are we to assume, then, that they arose simultaneously with the purpose of supporting each other? If so: wow. And

The Murchison meteorite was found to be 4.5 billion years old, and it was studded with amino acids—seventy-four types in all, eight of which are involved in the formation of earthly proteins.

Proteins can't exist without DNA, and DNA has no purpose without proteins. Are we to assume then that they arose simultaneously with the purpose of supporting each other? If so: wow.

You have at least 200,000 different types of protein laboring away inside you, and so far we understand what no more than about 2 percent of them do.

What genes specifically do is provide instructions for building proteins. Most of the useful things in the body are proteins. Some speed up chemical changes and are known as enzymes. Others convey chemical messages and are known as hormones.

COMPLICATED molecules. About a fifth of our body weight is made up of them. In simplest terms, a protein is a chain of amino acids. About a million different proteins have been identified so far, and nobody knows how many more are to be found. They are all made from just twenty amino acids

Por ejemplo, el impulso que corresponde a la nota «mi» captada por el oído, se desliza rápidamente de una neurona a otra hasta alcanzar a todas aquellas que contienen las moléculas de ácido RNA correspondiente a esta excitación particular. Las células fabrican de inmediato moléculas de la proteína correspondiente regida por este ácido, y realizamos la audición de dicha nota.

When you mix wheat flour and water together, the proteins in the flour combine to form a gluten network. This structure is what gives bread dough the strength and elasticity to capture all the bubbles and burbles produced by yeast in order to grow fluffy, chewy, and light when baked.

Insulin is not a cure for diabetes; it is a treatment. It enables the diabetic to burn sufficient carbohydrates so that proteins and fats may be added to the diet in sufficient quantities to provide energy for the economic burdens of life.

To complicate matters further, proteins must catalyze formation of the basic building blocks of cellular life such as sugars, lipids, glycolipids, nucleotides, and ATP (adenosine triphosphate, the main energy molecule of the cell).

early theories of the origin of life did not need to address, nor did they anticipate, this problem. Since scientists did not know about the information-bearing properties of DNA, or how the cell uses that functionally specified information to build proteins, they did not worry about explaining these features of life.

Proteins build cellular machines and structures, they carry and deliver cellular materials, and they catalyze chemical reactions that the cell needs to stay alive. Proteins also process genetic information.

The tar is an extremely rich collection of complex organic molecules, including the constituent parts of proteins and nucleic acids. The stuff of life, it turns out, can be very easily made.

So one way of looking at our trillion-celled bodies is that they are protein machines, although, as you know, I think we are more than machines! It sounds simple, but it isn't. For one thing, it takes over 100,000 different types of proteins to run our bodies. Let

over 80 percent of noncoding DNA is involved with regulating the production and assembly of gene-encoded proteins. A major discovery also found that "dark" DNA contains mechanisms by which environmental information can be used to modify the readout of protein-encoding genes. It turns out that dark DNA uses epigenetic mechanisms that enable a human cell with 19,000 gene blueprints to code for over a hundred thousand different protein molecules!

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.

The problem of different sensitivities of distinct protein groups to lysosomal inhibitors has remained unsolved and may have served as an important trigger in the future quest for a non-lysosomal proteolytic system that may be involved in at least certain aspects of intracellular protein degradation.

The 're-embryonisation of cancer cells' was an attractive concept because of the obvious behavioural similarities between the two cell types, embryonic and cancer, and the hunt was on in a number of labs to identify proteins that were present in both normal embryo cells and tumour cells, but not in healthy, fully developed adult cells.

Chromosomes were chemical mixtures, including proteins as well as a mysterious molecule called deoxyribonucleic acid, or DNA for short.
