Natural Product Identification
Common Name7b,12a-Dihydroxycholanoic acid
DescriptionPE(24:0/24:0), Also known as GPEtn(48:0), 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(24:0/24:0) Is a very strong basic compound (based on its pKa). PE(24:0/24:0) Is a phosphatidylethanolamine (PE or GPEtn). Within humans, PE(24:0/24:0) Participates in a number of enzymatic reactions. In particular, cytidine monophosphate and PE(24:0/24:0) Can be biosynthesized from CDP-ethanolamine and DG(24:0/24:0/0:0) Through its interaction with the enzyme choline/ethanolaminephosphotransferase. In addition, PE(24:0/24:0) Can be biosynthesized from PS(24:0/24:0) Through the action of the enzyme phosphatidylserine decarboxylase. The second involves the decarboxylation of PS. In humans, PE(24:0/24:0) Is involved in phosphatidylcholine biosynthesis. As is the case with diacylglycerols, glycerophosphoethanolamines can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. PE(24:0/24:0), In particular, consists of two chains of lignoceric acid at the C-1 and C-2 positions. The ethanolamine is then transferred from CDP-ethanolamine to phosphatidic acid to yield PE.
