Description2-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.
