Metabolite Identification
Common NamePC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z))
DescriptionPC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)), also known as PC(38:5) or phosphatidylcholine(38:5), 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(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) is considered to be a glycerophosphocholine lipid molecule. PC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) exists in all eukaryotes, ranging from yeast to humans. PC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) can be biosynthesized from S-adenosylmethionine and pe-nme2(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)); which is mediated by the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) can be biosynthesized from CDP-choline and DG(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)/0:0) through its interaction with the enzyme choline/ethanolaminephosphotransferase. Finally, PC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) and L-serine can be converted into choline and PS(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)); which is mediated by the enzyme phosphatidylserine synthase. In cattle, PC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) pathway and phosphatidylethanolamine biosynthesis pe(18:2(9Z,12Z)/20:3(8Z,11Z,14Z)) pathway.

Enzyme Details
1. Phosphatidylserine synthase 1
General function:
Not Available
Specific function:
Catalyzes a base-exchange reaction in which the polar head group of phosphatidylethanolamine (PE) or phosphatidylcholine (PC) is replaced by L-serine. In membranes, PTDSS1 catalyzes mainly the conversion of phosphatidylcholine. Also converts, in vitro and to a lesser extent, phosphatidylethanolamine (By similarity).
