Description: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. 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.
