PA(20:4(5Z,8Z,11Z,14Z)/24:1(15Z)) 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(20:4(5Z,8Z,11Z,14Z)/24:1(15Z)), in particular, consists of one chain of arachidonic acid at the C-1 position and one chain of nervonic acid at the C-2 position. Phosphatidic acids are quite rare but are extremely important as intermediates in the biosynthesis of triacylglycerols and phospholipids.
