Common NamePE(18:3(9Z,12Z,15Z)/20:1(11Z))
DescriptionPE(18:3(9Z,12Z,15Z)/20:1(11Z)), also known as pe(18:3(9z,12z,15z)/20:1(11z)) or GPEtn(38:4), 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(18:3(9Z,12Z,15Z)/20:1(11Z)) is considered to be a glycerophosphoethanolamine lipid molecule. PE(18:3(9Z,12Z,15Z)/20:1(11Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PE(18:3(9Z,12Z,15Z)/20:1(11Z)) participates in a number of enzymatic reactions, within cattle. In particular, PE(18:3(9Z,12Z,15Z)/20:1(11Z)) can be biosynthesized from PS(18:3(9Z,12Z,15Z)/20:1(11Z)); which is mediated by the enzyme phosphatidylserine decarboxylase. In addition, Cytidine monophosphate and PE(18:3(9Z,12Z,15Z)/20:1(11Z)) can be biosynthesized from CDP-ethanolamine and DG(18:3(9Z,12Z,15Z)/20:1(11Z)/0:0) through the action of the enzyme choline/ethanolaminephosphotransferase. In cattle, PE(18:3(9Z,12Z,15Z)/20:1(11Z)) is involved in the metabolic pathway called phosphatidylethanolamine biosynthesis pe(18:3(9Z,12Z,15Z)/20:1(11Z)) pathway.
