Metabolite Identification
Common NamePE(16:1(9Z)/20:1(11Z))
DescriptionPE(16:1(9Z)/20:1(11Z)), also known as GPEtn(16:1/20:1) or GPEtn(36:2), 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(16:1(9Z)/20:1(11Z)) is considered to be a glycerophosphoethanolamine lipid molecule. PE(16:1(9Z)/20:1(11Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PE(16:1(9Z)/20:1(11Z)) exists in all eukaryotes, ranging from yeast to humans. PE(16:1(9Z)/20:1(11Z)) participates in a number of enzymatic reactions, within cattle. In particular, PE(16:1(9Z)/20:1(11Z)) can be biosynthesized from PS(16:1(9Z)/20:1(11Z)) through the action of the enzyme phosphatidylserine decarboxylase. Furthermore, Cytidine monophosphate and PE(16:1(9Z)/20:1(11Z)) can be biosynthesized from CDP-ethanolamine and DG(16:1(9Z)/20:1(11Z)/0:0); which is mediated by the enzyme choline/ethanolaminephosphotransferase. Furthermore, Cytidine monophosphate and PE(16:1(9Z)/20:1(11Z)) can be biosynthesized from CDP-ethanolamine and DG(16:1(9Z)/20:1(11Z)/0:0) through its interaction with the enzyme choline/ethanolaminephosphotransferase. Finally, PE(16:1(9Z)/20:1(11Z)) can be biosynthesized from PS(16:1(9Z)/20:1(11Z)); which is catalyzed by the enzyme phosphatidylserine decarboxylase. In cattle, PE(16:1(9Z)/20:1(11Z)) is involved in a couple of metabolic pathways, which include phosphatidylethanolamine biosynthesis pe(16:1(9Z)/20:1(11Z)) pathway and phosphatidylcholine biosynthesis PC(16:1(9Z)/20:1(11Z)) pathway.
