Metabolite Identification
Common NamePC(18:0/18:2(9Z,12Z))
DescriptionPC(18:0/18:2(9Z,12Z)), also known as PC(18:0/18:2) or 18:0-18:2-PC, 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(18:0/18:2(9Z,12Z)) is considered to be a glycerophosphocholine lipid molecule. PC(18:0/18:2(9Z,12Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(18:0/18:2(9Z,12Z)) exists in all eukaryotes, ranging from yeast to humans. PC(18:0/18:2(9Z,12Z)) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(18:0/18:2(9Z,12Z)) can be biosynthesized from S-adenosylmethionine and pe-nme2(18:0/18:2(9Z,12Z)); which is mediated by the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(18:0/18:2(9Z,12Z)) can be biosynthesized from CDP-choline and DG(18:0/18:2(9Z,12Z)/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. Finally, PC(18:0/18:2(9Z,12Z)) and L-serine can be converted into choline and PS(18:0/18:2(9Z,12Z)) through its interaction with the enzyme phosphatidylserine synthase. In cattle, PC(18:0/18:2(9Z,12Z)) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(18:0/18:2(9Z,12Z)) pathway and phosphatidylethanolamine biosynthesis pe(18:0/18:2(9Z,12Z)) pathway.
