Phosphatidylserine is an important phospholipid membrane component which plays a key role in cell cycle signaling, specifically in relationship to apoptosis.Phosphatidylserine is a fatty molecule, a phospholipid, which contains both amino and fatty acids. The fatty acids include omega-3 and omega-6 fatty acid molecules. Phosphatidylserine is widely used as nutritional supplement.||Phosphatidyl-L-serine (Ptd-L-Ser) is a glycerophospholipid consisting of the amino acid serine connected to glycerol via a phosphodiester linkage and 2 fatty acids attached to the primary and secondary hydroxyls of the glycerol via ester linkages. Phosphatidyl-L-serine is a phospholipid component of the cell membrane and plays a key role in cell cycle signalling, specifically in relation to apoptosis. It has been suggested that dietary supplements of phosphatidyl-L-serine may reduce the risk of dementia and cognitive dysfunction in the elderly.||Synonyms:|1,2-Diacyl-sn-glycero-3-phospho-L-serine; Phosphatidylserine; Distearoyl phosphatidylserine; Phosphatidylserine(36:0); Dioctadecanoylphosphatidylserine; C42H82NO10P; CHEBI:84519; HMDB12378; (2S)-2-amino-3-[[(2R)-2,3-di(octadecanoyloxy)propoxy]-hydroxyphosphoryl]oxypropanoic acid||CAS No:|51446-62-9||Molecular Formula:|C42H82NO10P||Molecular Weight:|792.07||Appearance:|Yellow to orange or brown powder||Storage and Stability:|Store at -20°C.
