---|
Description | PE-NMe(22:5(4Z,7Z,10Z,13Z,16Z)/16:0) is a monomethylphosphatidylethanolamine. It is a glycerophospholipid, and is formed by sequential methylation of phosphatidylethanolamine as part of a mechanism for biosynthesis of phosphatidylcholine. Monomethylphosphatidylethanolamines 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-NMe(22:5(4Z,7Z,10Z,13Z,16Z)/16:0), in particular, consists of one 4Z,7Z,10Z,13Z,16Z-docosapentaenoyl chain to the C-1 atom, and one hexadecanoyl to the C-2 atom. Fatty acids containing 16, 18 and 20 carbons are the most common. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. |
