PA(O-16:0/18:0)
2-octadecanoyl-1-hexadecyl-sn-glycero-3-phosphate is an intermediate in ether lipid metabolism. 2-octadecanoyl-1-hexadecyl-sn-glycero-3-phosphate is converted from 1-octadecyl-glycerone-3-phosphate via 1-acylglycerol-3-phosphate O-acyltransferase. (EC: 2.3.1.51). 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. Ether lipids are called plasmalogens (1-O-1-alkenyl-2-acylglycerophospholipids) if these are glycerol-containing phospholipids with an unsaturated O-(1-alkenyl) (vinyl ether) group at the first position on the glycerol chain. Plasmalogens as well as some 1-O-alkyl lipids are ubiquitous and sometimes major parts of the cell membranes in mammals and anaerobic bacteria. In archaea, ether lipids are the major polar lipids in the cell envelope and their abundance is one of the major characteristics that separate this group of prokaryotes from the bacteria. In these cells, diphytanylglycerolipids or bipolar macrocyclic tetraethers can form covalently linked bilayers.
PA(O-20:4(5Z,8Z,11Z,14Z)/2:0)
PA(O-20:4(5Z,8Z,11Z,14Z)/2:0) 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(O-20:4(5Z,8Z,11Z,14Z)/2:0), in particular, consists of one 5Z,8Z,11Z,14Z-eicosatetraenoyl chain to the C-1 atom, and one acetyl to the C-2 atom. The oleic acid moiety is derived from vegetable oils, especially olive and canola oil, while the oleic acid moiety is derived from vegetable oils, especially olive and canola oil. Phosphatidic acids are quite rare but are extremely important as intermediates in the biosynthesis of triacylglycerols and phospholipids.
