Common NamePC(20:2(11Z,14Z)/20:2(11Z,14Z))
DescriptionPC(20:2(11Z,14Z)/20:2(11Z,14Z)), also known as phosphatidylcholine(40:4) or lecithin, 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(20:2(11Z,14Z)/20:2(11Z,14Z)) is considered to be a glycerophosphocholine lipid molecule. PC(20:2(11Z,14Z)/20:2(11Z,14Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(20:2(11Z,14Z)/20:2(11Z,14Z)) exists in all eukaryotes, ranging from yeast to humans. PC(20:2(11Z,14Z)/20:2(11Z,14Z)) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(20:2(11Z,14Z)/20:2(11Z,14Z)) can be biosynthesized from S-adenosylmethionine and pe-nme2(20:2(11Z,14Z)/20:2(11Z,14Z)); which is mediated by the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(20:2(11Z,14Z)/20:2(11Z,14Z)) can be biosynthesized from CDP-choline and DG(20:2(11Z,14Z)/20:2(11Z,14Z)/0:0) through the action of the enzyme choline/ethanolaminephosphotransferase. Finally, PC(20:2(11Z,14Z)/20:2(11Z,14Z)) and L-serine can be converted into choline and PS(20:2(11Z,14Z)/20:2(11Z,14Z)); which is mediated by the enzyme phosphatidylserine synthase. In cattle, PC(20:2(11Z,14Z)/20:2(11Z,14Z)) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(20:2(11Z,14Z)/20:2(11Z,14Z)) pathway and phosphatidylethanolamine biosynthesis pe(20:2(11Z,14Z)/20:2(11Z,14Z)) pathway.
