Metabolite Identification
Common NamePC(14:0/18:0)
DescriptionPC(14:0/18:0), also known as 1m-2S-PC or gpcho(32:0), 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(14:0/18:0) is considered to be a glycerophosphocholine lipid molecule. PC(14:0/18:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(14:0/18:0) exists in all eukaryotes, ranging from yeast to humans. PC(14:0/18:0) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(14:0/18:0) can be biosynthesized from S-adenosylmethionine and pe-nme2(14:0/18:0); which is mediated by the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(14:0/18:0) can be biosynthesized from CDP-choline and DG(14:0/18:0/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. Finally, PC(14:0/18:0) and L-serine can be converted into choline and PS(14:0/18:0) through its interaction with the enzyme phosphatidylserine synthase. In cattle, PC(14:0/18:0) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(14:0/18:0) pathway and phosphatidylethanolamine biosynthesis pe(14:0/18:0) 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).
