Side chain of serine
WebWhat types of interactions are involved in the catalytic triad of chymotrypsin, a serine protease enzyme that cleaves peptide bonds at the C-terminal of amino acid residues with non-polar side-chains (such as tryptophan, phenylalanine, and tyrosine) through a mechanism that utilizes both non-covalent and covalent catalysis within the enzyme … Serine (symbol Ser or S) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH 3 form under biological conditions), a carboxyl group (which is in the deprotonated −COO form under biological conditions), and a side chain consisting of a … See more This compound is one of the naturally occurring proteinogenic amino acids. Only the L-stereoisomer appears naturally in proteins. It is not essential to the human diet, since it is synthesized in the body from other See more The biosynthesis of serine starts with the oxidation of 3-phosphoglycerate (an intermediate from glycolysis) to 3-phosphohydroxypyruvate and NADH by phosphoglycerate dehydrogenase (EC 1.1.1.95).
