DL-O-Phosphoserine
DL-O-Phosphoserine is a normal metabolite in human biofluids and is a mixture of phosphoserine with two stereochemical structures (D-type and L-type O-phospho-serine). O-phospho-L-serine is a competitive inhibitor of serine racemase and phagocytosis. O-phospho-L-serine inhibits the enzymatic reaction by competing with the active site of serine racemase, thereby affecting the production of D-serine. O-phospho-L-serine also mimics the phosphatidylserine head group, binds to the phosphatidylserine receptor, interferes with phagocytic signal transduction, and partially blocks the phagocytosis of apoptotic cells by cells. O-phospho-L-serin can be used in the research of retinal regeneration, bone repair, and insect growth and development[1][2].
