Common NamePA(16:0/16:0)
DescriptionPA(16:0/16:0) 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(16:0/16:0), in particular, consists of one chain of palmitic acid at the C-1 position and one chain of palmitic acid at the C-2 position. Phosphatidic acids are quite rare but are extremely important as intermediates in the biosynthesis of triacylglycerols and phospholipids. Phospholipase Ds (PLDs), which catalyze the conversion of glycerolphospholipids, particularly phosphatidylcholine, to PAs and the conversion of N-arachidonoyl-phosphatidylethanolamine (NAPE) to anandamide and PAs are activated by several inflammatory mediators including bradykinin, ATP and glutamate. Circumstantial evidence that PAs are converted to DAGs. (PMID: 12618218 , 16185776 ).
