First, about protein composition. Proteins are composed of small molecules called amino acids. An amino acid is considered as a carbon atom attached to four different chemical groups. Three of these chemical groups are always the same. They are an amino group, a carboxyl group, and a hydrogen...

A simple amino acid is an effective chelating agent. Such molecules can be products of protein hydrolysis, although there is no definite evidence for their importance in natural water systems. 氨基酸、肽和蛋白质分解产品。 简单的氨基酸是有效的螯合剂。 这样分子可以是蛋白质加水分解产品,虽然没有确定...
During protein synthesis, amino acids are linked together in a specific order. The amino acid chain, called a polypeptide, then folds into a three dimensional shape to make a functional protein. Proteins are important components of body structures, such as bone, hair, nails and muscle. However...
Amino acid, any of a group of organic molecules that consist of a basic amino group, an acidic carboxyl group, and a unique organic side chain. The term amino acid is short for α-amino [alpha-amino] carboxylic acid. Examples of amino acids include glyci
Tryptophan, an amino acid that is nutritionally important and occurs in small amounts in proteins. It is an essential amino acid, meaning that humans and certain other animals cannot synthesize it and must obtain it from their diets. Infants require grea
Inconsistent results on the association between evolutionary rates and amino acid composition of proteins have been reported in eukaryotes. However, there are few studies of how amino acid composition can influence evolutionary rates in bacteria. Thus, w
