Phosphatidylethanolamine (chicken egg)

Phosphatidylethanolamine is the most abundant phospholipid in prokaryotes and the second most abundant found in the membrane of mammalian, plant, and yeast cells, comprising approximately 25% of total mammalian phospholipids. In the brain, phosphatidylethanolamine comprises almost half of the total phospholipids. It is synthesized mainly through the cytidine diphosphate-ethanolamine and phosphatidylserine decarboxylation pathways, which occur in the endoplasmic reticulum (ER) and mitochondrial membranes, respectively. It is a precursor in the synthesis of phosphatidylcholine and arachidonoyl ethanolamide (Cay-90050) and is a source of ethanolamine used in various cellular functions. In E. coli, phosphatidylethanolamine deficiency prevents proper assembly of lactose permease, suggesting a role as a lipid chaperone. It is a cofactor in the propagation of prions in vitro and can convert recombinant mammalian proteins into infectious molecules even in the absence of RNA. This product contains phosphatidylcholine molecular species with primarily C16:0 and C18:1 fatty acyl chain lengths. [Matreya, LLC. Catalog No. 1045]CAS Number: 39382-08-6. Synonyms: PE (egg).
