Common NamePA(18:1(11Z)/10:0)
DescriptionPA(18:1(11Z)/10:0) 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(18:1(11Z)/10:0), in particular, consists of one 11Z-octadecenoyl chain at the C-1 position and one decanoyl chain at the C-2 position. Phosphatidic acids are quite rare but are extremely important as intermediates in the biosynthesis of triacylglycerols and phospholipids. PAs are biologically active lipids that can stimulate a large range of responses in many different cell types. Diacylglycerols (DAGs) can be converted to PAs by DAG kinases. 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. PAs activate downstream signaling pathways such as PKCs and mitogen-activated protein kinases (MAPKs). Circumstantial evidence that PAs are converted to DAGs. (PMID: 12618218 , 16185776 ).
