Metabolite Identification
Common NamePC(18:0/20:4(8Z,11Z,14Z,17Z))
DescriptionPC(18:0/20:4(8Z,11Z,14Z,17Z)), also known as pc(18:0/20:4(8z,11z,14z,17z)) or pc(18:0/20:4(8z,11z,14z,17z)), 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(18:0/20:4(8Z,11Z,14Z,17Z)) is considered to be a glycerophosphocholine lipid molecule. PC(18:0/20:4(8Z,11Z,14Z,17Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(18:0/20:4(8Z,11Z,14Z,17Z)) exists in all eukaryotes, ranging from yeast to humans. PC(18:0/20:4(8Z,11Z,14Z,17Z)) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(18:0/20:4(8Z,11Z,14Z,17Z)) can be biosynthesized from S-adenosylmethionine and pe-nme2(18:0/20:4(8Z,11Z,14Z,17Z)); which is catalyzed by the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(18:0/20:4(8Z,11Z,14Z,17Z)) can be biosynthesized from CDP-choline and DG(18:0/20:4(8Z,11Z,14Z,17Z)/0:0); which is mediated by the enzyme choline/ethanolaminephosphotransferase. Finally, PC(18:0/20:4(8Z,11Z,14Z,17Z)) and L-serine can be converted into choline and PS(18:0/20:4(8Z,11Z,14Z,17Z)); which is mediated by the enzyme phosphatidylserine synthase. In cattle, PC(18:0/20:4(8Z,11Z,14Z,17Z)) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(18:0/20:4(8Z,11Z,14Z,17Z)) pathway and phosphatidylethanolamine biosynthesis pe(18:0/20:4(8Z,11Z,14Z,17Z)) pathway.

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).
