Metabolite Identification
Common NamePC(20:0/22:4(7Z,10Z,13Z,16Z))
DescriptionPC(20:0/22:4(7Z,10Z,13Z,16Z)), also known as pc(20:0/22:4(7z,10z,13z,16z)) or pc(20:0/22:4(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. Thus, PC(20:0/22:4(7Z,10Z,13Z,16Z)) is considered to be a glycerophosphocholine lipid molecule. PC(20:0/22:4(7Z,10Z,13Z,16Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(20:0/22:4(7Z,10Z,13Z,16Z)) exists in all eukaryotes, ranging from yeast to humans. PC(20:0/22:4(7Z,10Z,13Z,16Z)) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(20:0/22:4(7Z,10Z,13Z,16Z)) can be biosynthesized from S-adenosylmethionine and pe-nme2(20:0/22:4(7Z,10Z,13Z,16Z)) through its interaction with the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(20:0/22:4(7Z,10Z,13Z,16Z)) can be biosynthesized from CDP-choline and DG(20:0/22:4(7Z,10Z,13Z,16Z)/0:0) through its interaction with the enzyme choline/ethanolaminephosphotransferase. Finally, PC(20:0/22:4(7Z,10Z,13Z,16Z)) and L-serine can be converted into choline and PS(20:0/22:4(7Z,10Z,13Z,16Z)) through its interaction with the enzyme phosphatidylserine synthase. In cattle, PC(20:0/22:4(7Z,10Z,13Z,16Z)) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(20:0/22:4(7Z,10Z,13Z,16Z)) pathway and phosphatidylethanolamine biosynthesis pe(20:0/22:4(7Z,10Z,13Z,16Z)) pathway.
