Proteins are large, organic, nitrogen-containing molecules that are essential both to the structure and to the function of all living cells. Exceedingly complex themselves, the protein molecules have as their structural units much simpler compounds...

In humans, there is a large amount of protein turnover. Approximately one pound of protein is degraded and re-synthesized each day. Most of the amino acids liberated by protein degradation are used again in the re-synthesis of new protein but about ten...

Proteins are vital components of all forms of life, and are important to living cells both structurally and functionally. They are made up of amino acids linked together in a chain by a sequence of peptide bonds. A peptide bond links the amino group...

(from Greek, proteios: primary) A protein is a complex MOLECULE, composed of various combinations of any of the twenty AMINO ACIDS (each made of carbon, hydrogen, oxygen and nitrogen) with a side chain, usually containing sulphur and often phosphorous....

Proteins are large organic compounds made of amino acids arranged in a linear chain and joined together by peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by a gene...

NO FAT-AND MAY FIGHT CANCER Whey protein, once thought to be a useless by-product of cheese production, has recently become one of the most popular protein supplements. This is clue, in part, to the development of several methods for distilling whey into a...

Two professors at the University of Oklahoma say they've developed a protein that can stop the spread of certain cancer cells without damaging normal cells.Thomas Pento and Roger Harrison helped develop a fusion protein that keeps some types of cancer cells from ingesting a vital...

China said Monday it was investigating the sale of fake blood protein, a potentially dangerous and widespread practice that underscores the country's problems with product safety.State media reported one death from use of the counterfeits, but authorities have not said whether anyone has fallen ill.A...
