PE-NMe(18:4(6Z,9Z,12Z,15Z)/18:4(6Z,9Z,12Z,15Z)) is a monomethylphosphatidylethanolamine. It is a glycerophospholipid, and it 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(18:4(6Z,9Z,12Z,15Z)/18:4(6Z,9Z,12Z,15Z)), in particular, consists of one chain of stearidonic acid at the C-1 position and one chain of stearidonic acid at the C-2 position. Fatty acids containing 16, 18 and 20 carbons are the most common. Phospholipids are ubiquitous in nature. They are key components of the cell lipid bilayer and are involved in metabolism and signaling.
