Common NamePC(O-22:0/22:5(7Z,10Z,13Z,16Z,19Z))
DescriptionPC(O-22:0/22:5(7Z,10Z,13Z,16Z,19Z)) is a phosphatidylchloline (PC or GPCho). It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidylcholines can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PC(O-22:0/22:5(7Z,10Z,13Z,16Z,19Z)), in particular, consists of one docosanyl chain to the C-1 atom, and one 7Z,10Z,13Z,16Z,19Z-docosapentaenoyl to the C-2 atom. In E. coli, PCs can be found in the integral component of the cell outer membrane. They are hydrolyzed by Phospholipases to a 2-acylglycerophosphocholine and a carboxylate. PCs can also be synthesized by the addition of choline to CDP-activated 1,2-diacylglycerol. A third route to PC synthesis involves the conversion of either PS or PE to PC.
