Chemical Information
FooDB NamePC(o-18:1(9Z)/20:1(11Z))
DescriptionPC(o-18:1(9Z)/20:1(11Z)) is a phosphatidylcholine (PC or GPCho). It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphocholines 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. PC(o-18:1(9Z)/20:1(11Z)), in particular, consists of one chain of Oleyl alcohol at the C-1 position and one chain of eicosenoic acid at the C-2 position. The Oleyl alcohol moiety is derived from beef fat, fish oil, while the eicosenoic acid moiety is derived from vegetable oils and cod oils. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. PCs can be synthesized via three different routes. In one route, choline is activated first by phosphorylation and then by coupling to CDP prior to attachment to phosphatidic acid. PCs can also 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. [HMDB]

Classification
Description Belongs to the class of organic compounds known as 1-alkyl,2-acylglycero-3-phosphocholines. These are glycerophosphocholines that carry exactly one acyl chain attached to the glycerol moiety through an ester linkage at the O2-position, and one alkyl chain attached through an ether linkage at the O1-position.
