Metabolite Identification
Common NamePC(20:2(11Z,14Z)/24:0)
DescriptionPC(20:2(11Z,14Z)/24:0), also known as pc(20:2(11z,14z)/24:0) or PC(44:2), 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. PC(20:2(11Z,14Z)/24:0) is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). PC(20:2(11Z,14Z)/24:0) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(20:2(11Z,14Z)/24:0) can be biosynthesized from S-adenosylmethionine and pe-nme2(20:2(11Z,14Z)/24:0) through the action of the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(20:2(11Z,14Z)/24:0) can be biosynthesized from CDP-choline and DG(20:2(11Z,14Z)/24:0/0:0) through the action of the enzyme choline/ethanolaminephosphotransferase. Finally, PC(20:2(11Z,14Z)/24:0) and L-serine can be converted into choline and PS(20:2(11Z,14Z)/24:0) through its interaction with the enzyme phosphatidylserine synthase. In cattle, PC(20:2(11Z,14Z)/24:0) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(20:2(11Z,14Z)/24:0) pathway and phosphatidylethanolamine biosynthesis pe(20:2(11Z,14Z)/24:0) pathway.
