PE(24:1(15Z)/24:1(15Z))

(2-aminoethoxy)[(2R)-2,3-bis[(15Z)-tetracos-15-enoyloxy]propoxy]phosphinic acid

PE(24:1(15Z)/24:1(15Z)) is a phosphatidylethanolamine (PE or GPEtn). It is a glycerophospholipid in which a phosphorylethanolamine moiety occupies a glycerol substitution site. 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. Fatty acids containing 16, 18 and 20 carbons are the most common. PE(24:1(15Z)/24:1(15Z)), in particular, consists of two chains of nervonic acid at the C-1 and C-2 positions. The nervonic acid moieties are derived from fish oils. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling.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. 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. PE synthesis can occur via two pathways. The first requires that ethanolamine be activated by phosphorylation and then coupled to CDP. The ethanolamine is then transferred from CDP-ethanolamine to phosphatidic acid to yield PE. The second involves the decarboxylation of PS.

PE-NMe2(22:1(13Z)/24:1(15Z))

[2-(dimethylamino)ethoxy]({3-[(13Z)-docos-13-enoyloxy]-2-[(15Z)-tetracos-15-enoyloxy]propoxy})phosphinic acid

C53H102NO8P (911.7342662)

PE-NMe2(22:1(13Z)/24:1(15Z)) is a dimethylphosphatidylethanolamine. It is a glycerophospholipid, and it is formed by sequential methylation of phosphatidylethanolamine as part of a mechanism for biosynthesis of phosphatidylcholine. Dimethylphosphatidylethanolamines are usually found at trace levels in animal or plant tissues. They can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. PE-NMe2(22:1(13Z)/24:1(15Z)), in particular, consists of one chain of erucic acid at the C-1 position and one chain of nervonic acid at the C-2 position. Fatty acids containing 16, 18 and 20 carbons are the most common. Phospholipids are ubiquitous in nature. They are key components of the cell lipid bilayer and are involved in metabolism and signaling.
