Metabolite Identification
Common NamePE(18:0/18:0)
DescriptionPE(18:0/18:0), also known as pe(18:0/18:0) or pe(18:0/18:0), 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(18:0/18:0) is considered to be a glycerophosphoethanolamine lipid molecule. PE(18:0/18:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PE(18:0/18:0) exists in all living species, ranging from bacteria to humans. PE(18:0/18:0) participates in a number of enzymatic reactions, within cattle. In particular, Cytidine monophosphate and PE(18:0/18:0) can be biosynthesized from CDP-ethanolamine and DG(18:0/18:0/0:0); which is mediated by the enzyme choline/ethanolaminephosphotransferase. Furthermore, PE(18:0/18:0) can be biosynthesized from PS(18:0/18:0) through the action of the enzyme phosphatidylserine decarboxylase. Furthermore, PE(18:0/18:0) can be biosynthesized from PS(18:0/18:0); which is mediated by the enzyme phosphatidylserine decarboxylase. Finally, Cytidine monophosphate and PE(18:0/18:0) can be biosynthesized from CDP-ethanolamine and DG(18:0/18:0/0:0) through the action of the enzyme choline/ethanolaminephosphotransferase. In cattle, PE(18:0/18:0) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(18:0/18:0) pathway and phosphatidylethanolamine biosynthesis pe(18:0/18:0) pathway.
