Metabolite Identification
Common NamePE(20:1(11Z)/22:1(13Z))
DescriptionPE(20:1(11Z)/22:1(13Z)), also known as GPEtn(20:1/22:1) or PE(42:2), 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. PE(20:1(11Z)/22:1(13Z)) is possibly soluble (in water) and a very strong basic compound (based on its pKa). PE(20:1(11Z)/22:1(13Z)) participates in a number of enzymatic reactions, within cattle. In particular, PE(20:1(11Z)/22:1(13Z)) can be biosynthesized from PS(20:1(11Z)/22:1(13Z)) through its interaction with the enzyme phosphatidylserine decarboxylase. Furthermore, Cytidine monophosphate and PE(20:1(11Z)/22:1(13Z)) can be biosynthesized from CDP-ethanolamine and DG(20:1(11Z)/22:1(13Z)/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. Furthermore, Cytidine monophosphate and PE(20:1(11Z)/22:1(13Z)) can be biosynthesized from CDP-ethanolamine and DG(20:1(11Z)/22:1(13Z)/0:0); which is mediated by the enzyme choline/ethanolaminephosphotransferase. Finally, PE(20:1(11Z)/22:1(13Z)) can be biosynthesized from PS(20:1(11Z)/22:1(13Z)) through the action of the enzyme phosphatidylserine decarboxylase. In cattle, PE(20:1(11Z)/22:1(13Z)) is involved in a couple of metabolic pathways, which include phosphatidylethanolamine biosynthesis pe(20:1(11Z)/22:1(13Z)) pathway and phosphatidylcholine biosynthesis PC(20:1(11Z)/22:1(13Z)) pathway.
