Common NamePE(20:3(5Z,8Z,11Z)/18:0)
DescriptionPE(20:3(5Z,8Z,11Z)/18:0) 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. The first requires that ethanolamine be activated by phosphorylation and then coupled to CDP. PE(20:3(5Z,8Z,11Z)/18:0), In particular, consists of one chain of mead acid at the C-1 position and one chain of stearic acid at the C-2 position. PE synthesis can occur via two pathways. PE(20:3(5Z,8Z,11Z)/18:0) Is a very strong basic compound (based on its pKa). Within humans, PE(20:3(5Z,8Z,11Z)/18:0) Participates in a number of enzymatic reactions. In particular, PE(20:3(5Z,8Z,11Z)/18:0) Can be biosynthesized from PS(20:3(5Z,8Z,11Z)/18:0) Through its interaction with the enzyme phosphatidylserine decarboxylase. In addition, cytidine monophosphate and PE(20:3(5Z,8Z,11Z)/18:0) Can be biosynthesized from CDP-ethanolamine and DG(20:3(5Z,8Z,11Z)/18:0/0:0) Through the action of the enzyme choline/ethanolaminephosphotransferase. The second involves the decarboxylation of PS. In humans, PE(20:3(5Z,8Z,11Z)/18:0) Is involved in phosphatidylethanolamine biosynthesis. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. 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. It is a glycerophospholipid in which a phosphorylethanolamine moiety occupies a glycerol substitution site. While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. PE(20:3(5Z,8Z,11Z)/18:0) Is a phosphatidylethanolamine (PE or GPEtn). PEs are neutral zwitterions at physiological pH. They mostly have palmitic or stearic acid on carbon 1 and a long chain unsaturated fatty acid (e.G. 18:2, 20:4 And 22:6) On carbon 2. The mead acid moiety is derived from fish oils, liver and kidney, while the stearic acid moiety is derived from animal fats, coco butter and sesame oil.
