Biochem/physiol Actions

1,2-Diacyl-sn-glycero-3-phospho-L-serine or phosphatidylserine (PS) is a structurally diverse acidic phospholipid having fatty acid ester at the glycerol sn positions. Bovine brain cortex based PS is a potent brain nutrient. It favors neurotransmission and may improve memory in dementia. PS is also the major membrane phospholipid associated with the nuclear membrane, myelin, endoplasmic reticulum, Golgi and mitochondria. The synthesis of PS is catalyzed by phosphatidylserine synthase 1 from L-serine and CDP-diacylglycerol in the mitochondria-associated membrane (MAM) domains of the endoplasmic reticulum. PS is externalized during phagocytosis and is dysregulated in tumors making it a potential marker for therapeutic targeting.
A slowly metabolized structural phospholipid found mainly in gray matter.
