Metabolite Identification
Common NamePC(16:0/20:0)
DescriptionPC(16:0/20:0), also known as gpcho(36:0) or PC 16:0/20:0, belongs to the class of organic compounds known as phosphatidylcholines. These are glycerophosphocholines in which the two free -OH are attached to one fatty acid each through an ester linkage. Thus, PC(16:0/20:0) is considered to be a glycerophosphocholine lipid molecule. PC(16:0/20:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(16:0/20:0) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(16:0/20:0) can be biosynthesized from S-adenosylmethionine and pe-nme2(16:0/20:0) through the action of the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(16:0/20:0) can be biosynthesized from CDP-choline and DG(16:0/20:0/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. Finally, PC(16:0/20:0) and L-serine can be converted into choline and PS(16:0/20:0) through its interaction with the enzyme phosphatidylserine synthase. In cattle, PC(16:0/20:0) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(16:0/20:0) pathway and phosphatidylethanolamine biosynthesis pe(16:0/20:0) pathway.
