Metabolite Identification
Common NamePE(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z))
DescriptionPE(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)), also known as GPEtn(42:6) or pe(20:2(11z,14z)/22:4(7z,10z,13z,16z)), 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(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) is considered to be a glycerophosphoethanolamine lipid molecule. PE(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PE(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) participates in a number of enzymatic reactions, within cattle. In particular, PE(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) can be biosynthesized from PS(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)); which is catalyzed by the enzyme phosphatidylserine decarboxylase. Furthermore, Cytidine monophosphate and PE(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) can be biosynthesized from CDP-ethanolamine and DG(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)/0:0); which is mediated by the enzyme choline/ethanolaminephosphotransferase. Furthermore, Cytidine monophosphate and PE(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) can be biosynthesized from CDP-ethanolamine and DG(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. Finally, PE(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) can be biosynthesized from PS(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)); which is catalyzed by the enzyme phosphatidylserine decarboxylase. In cattle, PE(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) is involved in a couple of metabolic pathways, which include phosphatidylethanolamine biosynthesis pe(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) pathway and phosphatidylcholine biosynthesis PC(20:2(11Z,14Z)/22:4(7Z,10Z,13Z,16Z)) pathway.
