2-(9Z,12Z-octadecadienoyl)-1-(1Z-hexadecenyl)-sn-glycero-3-phosphate is an intermediate of ether lipid metabolism. Ether lipids are lipids in which one or more of the carbon atoms on glycerol is bonded to an alkyl chain via an ether linkage, as opposed to the usual ester linkage. 2-(9Z,12Z-octadecadienoyl)-1-(1Z-hexadecenyl)-sn-glycero-3-phosphate is irreversibly produced from 2-(9Z,12Z-octadecadienoyl)-1-(1Z-hexadecenyl))-sn-glycero-3-phosphoethanolamine via the enzyme phospholipase D (EC: 3.1.4.4). Plasmalogens are glycerol ether phospholipids. They are of two types, alkyl ether (-O-CH2-) and alkenyl ether (-O-CH=CH-). Dihydroxyacetone phosphate (DHAP) serves as the glycerol precursor for the synthesis of plasmalogens. Three major classes of plasmalogens have been identified: choline, ethanolamine and serine derivatives. Ethanolamine plasmalogen is prevalent in myelin. Choline plasmalogen is abundant in cardiac tissue. Usually, the highest proportion of the plasmalogen form is in the ethanolamine class with rather less in choline, and commonly little or none in other phospholipids such as phosphatidylinositol. In choline plasmalogens of most tissues, a higher proportion is often of the O-alkyl rather than the O-alkenyl form, but the reverse tends to be true in heart lipids. In animal tissues, the alkyl and alkenyl moieties in both non-polar and phospholipids tend to be rather simple in composition with 16:0, 18:0 and 18:1 (double bond in position 9) predominating. Ether analogues of triacylglycerols, i.e. 1-alkyldiacyl-sn-glycerols, are present at trace levels only if at all in most animal tissues, but they can be major components of some marine lipids. 2-(9Z,12Z-octadecadienoyl)-1-(1Z-hexadecenyl)-sn-glycero-3-phosphate is an intermediate of ether lipid metabolism. Ether lipids are lipids in which one or more of the carbon atoms on glycerol is bonded to an alkyl chain via an ether linkage, as opposed to the usual ester linkage.

PA(15:0/18:3(6Z,9Z,12Z))

[(2R)-2-[(6Z,9Z,12Z)-octadeca-6,9,12-trienoyloxy]-3-(pentadecanoyloxy)propoxy]phosphonic acid

C36H65O8P (656.441682)

PA(15:0/18:3(6Z,9Z,12Z)) is a phosphatidic acid. It is a glycerophospholipid in which a phosphate moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidic acids 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. PA(15:0/18:3(6Z,9Z,12Z)), in particular, consists of one chain of pentadecanoic acid at the C-1 position and one chain of gamma-linolenic acid at the C-2 position. Phosphatidic acids are quite rare but are extremely important as intermediates in the biosynthesis of triacylglycerols and phospholipids.
