Metabolite Identification
Common NamePC(16:0/18:3(9Z,12Z,15Z))
DescriptionPC(16:0/18:3(9Z,12Z,15Z)), also known as PC(16:0/18:3) 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(16:0/18:3(9Z,12Z,15Z)) is considered to be a glycerophosphocholine lipid molecule. PC(16:0/18:3(9Z,12Z,15Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(16:0/18:3(9Z,12Z,15Z)) exists in all eukaryotes, ranging from yeast to humans. PC(16:0/18:3(9Z,12Z,15Z)) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(16:0/18:3(9Z,12Z,15Z)) can be biosynthesized from S-adenosylmethionine and pe-nme2(16:0/18:3(9Z,12Z,15Z)) through its interaction with the enzyme phosphatidylethanolamine N-methyltransferase. In addition, Cytidine monophosphate and PC(16:0/18:3(9Z,12Z,15Z)) can be biosynthesized from CDP-choline and DG(16:0/18:3(9Z,12Z,15Z)/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. In cattle, PC(16:0/18:3(9Z,12Z,15Z)) is involved in the metabolic pathway called phosphatidylcholine biosynthesis PC(16:0/18:3(9Z,12Z,15Z)) 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).
