MSH: A non-essential amino acid occurring in natural form as the L-isomer. It is synthesized from GLYCINE or THREONINE. It is involved in the biosynthesis of PURINES; PYRIMIDINES; and other amino acids.,CSP: naturally occurring nonessential aminoacid, chemical name 2-amino-3-hydroxypropionic acid; it may be synthesized from glycine or threonine and is involved in the biosynthesis of purines, pyrimidines, and other amino acids.,NCI: Amino acid with side chain -CH2OH.,NCI: A non-essential amino acid in humans (synthesized by the body), Serine is present and functionally important in many proteins. With an alcohol group, serine is needed for the metabolism of fats, fatty acids, and cell membranes; muscle growth; and a healthy immune system. It also plays a major role in pyrimidine, purine, creatine, and porphyrin biosynthetic pathways. Serine is also found at the active site of the serine protease enzyme class that includes trypsin and chymotrypsin. (NCI04)
