DescriptionECHEMI Editorial ReferenceL-Serine, one of the so-called non-essential amino acids, plays a central role in cellular proliferation.
Solid
L-serine is the L-enantiomer of serine. It has a role as a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a serine family amino acid, a proteinogenic amino acid, a L-alpha-amino acid and a serine. It is a conjugate base of a L-serinium. It is a conjugate acid of a L-serinate. It is an enantiomer of a D-serine. It is a tautomer of a L-serine zwitterion.|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.|Serine is 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)|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.Basic Info-
