Common NamePE(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z))
DescriptionPE(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)), also known as pe(18:1(9z)/22:6(4z,7z,10z,13z,16z,19z)) or GPEtn(18:1/22:6), 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(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) is considered to be a glycerophosphoethanolamine lipid molecule. PE(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PE(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) participates in a number of enzymatic reactions, within cattle. In particular, PE(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) can be biosynthesized from PS(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) through the action of the enzyme phosphatidylserine decarboxylase. Furthermore, Cytidine monophosphate and PE(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) can be biosynthesized from CDP-ethanolamine and DG(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. Furthermore, Cytidine monophosphate and PE(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) can be biosynthesized from CDP-ethanolamine and DG(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. Finally, PE(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) can be biosynthesized from PS(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)); which is catalyzed by the enzyme phosphatidylserine decarboxylase. In cattle, PE(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) is involved in a couple of metabolic pathways, which include phosphatidylethanolamine biosynthesis pe(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) pathway and phosphatidylcholine biosynthesis PC(18:1(9Z)/22:6(4Z,7Z,10Z,13Z,16Z,19Z)) pathway.
