Metabolite Identification
Common NamePE(15:0/20:0)
DescriptionPE(15:0/20:0), also known as GPEtn(35:0), 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(15:0/20:0) is considered to be a glycerophosphoethanolamine lipid molecule. PE(15:0/20:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PE(15:0/20:0) participates in a number of enzymatic reactions, within cattle. In particular, Cytidine monophosphate and PE(15:0/20:0) can be biosynthesized from CDP-ethanolamine and DG(15:0/20:0/0:0) through its interaction with the enzyme choline/ethanolaminephosphotransferase. Furthermore, PE(15:0/20:0) can be biosynthesized from PS(15:0/20:0) through the action of the enzyme phosphatidylserine decarboxylase. Furthermore, PE(15:0/20:0) can be biosynthesized from PS(15:0/20:0); which is catalyzed by the enzyme phosphatidylserine decarboxylase. Finally, Cytidine monophosphate and PE(15:0/20:0) can be biosynthesized from CDP-ethanolamine and DG(15:0/20:0/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. In cattle, PE(15:0/20:0) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(15:0/20:0) pathway and phosphatidylethanolamine biosynthesis pe(15:0/20:0) pathway.
