DescriptionDL-O-Phosphoserine, also known as DL-O-phosphorylserine or DL-O-serine phosphate, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). DL-O-Phosphoserine is a very strong basic compound (based on its pKa). DL-O-Phosphoserine exists in all living species, ranging from bacteria to humans. Within yeast, DL-O-phosphoserine participates in a number of enzymatic reactions. In particular, oxoglutaric acid and DL-O-phosphoserine can be biosynthesized from phosphohydroxypyruvic acid and L-glutamic acid through its interaction with the enzyme phosphoserine transaminase. In addition, DL-O-phosphoserine can be converted into L-serine; which is mediated by the enzyme phosphoserine phosphatase. In yeast, DL-O-phosphoserine is involved in the metabolic pathway called the serine metabolism pathway.
