| Description | PC(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)), also known as pc(20:3(8z,11z,14z)/22:5(4z,7z,10z,13z,16z)) or pc(20:3(8z,11z,14z)/22:5(4z,7z,10z,13z,16z)), 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(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). PC(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) can be biosynthesized from S-adenosylmethionine and pe-nme2(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) through the action of the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) can be biosynthesized from CDP-choline and DG(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. Finally, PC(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) and L-serine can be converted into choline and PS(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) through its interaction with the enzyme phosphatidylserine synthase. In cattle, PC(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) pathway and phosphatidylethanolamine biosynthesis pe(20:3(8Z,11Z,14Z)/22:5(4Z,7Z,10Z,13Z,16Z)) pathway. |
