Common Name3b,5a,6b-Cholestanetriol
DescriptionPE(16:0/18:0), Also known as PE(34:0), Belongs to the class of organic compounds known as phosphatidylethanolamines. These are glycerophosphoetahnolamines in which two fatty acids are bonded to the glycerol moiety through ester linkages. Thus, PE(16:0/18:0) Is considered to be a glycerophosphoethanolamine lipid molecule. PE(16:0/18:0) Is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PE(16:0/18:0) Exists in all living species, ranging from bacteria to humans. Within humans, PE(16:0/18:0) Participates in a number of enzymatic reactions. In particular, cytidine monophosphate and PE(16:0/18:0) Can be biosynthesized from CDP-ethanolamine and DG(16:0/18:0/0:0); Which is mediated by the enzyme choline/ethanolaminephosphotransferase. In addition, PE(16:0/18:0) Can be biosynthesized from PS(16:0/18:0) Through the action of the enzyme phosphatidylserine decarboxylase. A phosphatidylethanolamine 34:1 Zwitterion obtained by transfer of a proton from the phosphate to the amino group of 1-hexadecanoyl-2-octadecanoyl-sn-glycero-3-phosphoethanolamine. 3b,5a,6b-Cholestanetriol is found in Echinogorgia aurantiaca, Eunicea laciniata and Plexaurella grisea. In humans, PE(16:0/18:0) Is involved in phosphatidylcholine biosynthesis.
