Common NamePC(14:0/20:4(5Z,8Z,11Z,14Z))
DescriptionPC(14:0/20:4(5Z,8Z,11Z,14Z)), also known as phosphatidylcholine(14:0/20:4) or gpcho(14:0/20:4), 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(14:0/20:4(5Z,8Z,11Z,14Z)) is considered to be a glycerophosphocholine lipid molecule. PC(14:0/20:4(5Z,8Z,11Z,14Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(14:0/20:4(5Z,8Z,11Z,14Z)) exists in all eukaryotes, ranging from yeast to humans. PC(14:0/20:4(5Z,8Z,11Z,14Z)) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(14:0/20:4(5Z,8Z,11Z,14Z)) can be biosynthesized from S-adenosylmethionine and pe-nme2(14:0/20:4(5Z,8Z,11Z,14Z)) through its interaction with the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(14:0/20:4(5Z,8Z,11Z,14Z)) can be biosynthesized from CDP-choline and DG(14:0/20:4(5Z,8Z,11Z,14Z)/0:0) through its interaction with the enzyme choline/ethanolaminephosphotransferase. Finally, PC(14:0/20:4(5Z,8Z,11Z,14Z)) and L-serine can be converted into choline and PS(14:0/20:4(5Z,8Z,11Z,14Z)); which is mediated by the enzyme phosphatidylserine synthase. In cattle, PC(14:0/20:4(5Z,8Z,11Z,14Z)) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(14:0/20:4(5Z,8Z,11Z,14Z)) pathway and phosphatidylethanolamine biosynthesis pe(14:0/20:4(5Z,8Z,11Z,14Z)) pathway.

Enzymes

General function:
Involved in calcium ion binding
Specific function:
Has primarily calcium-dependent phospholipase and lysophospholipase activities, with a major role in membrane lipid remodeling and biosynthesis of lipid mediators of the inflammatory response (By similarity). Plays an important role in embryo implantation and parturition through its ability to trigger prostanoid production (By similarity). Preferentially hydrolyzes the ester bond of the fatty acyl group attached at sn-2 position of phospholipids (phospholipase A2 activity). Selectively hydrolyzes sn-2 arachidonoyl group from membrane phospholipids, providing the precursor for eicosanoid biosynthesis via the cyclooxygenase pathway. In an alternative pathway of eicosanoid biosynthesis, hydrolyzes sn-2 fatty acyl chain of eicosanoid lysophopholipids to release free bioactive eicosanoids. Hydrolyzes the ester bond of the fatty acyl group attached at sn-1 position of phospholipids (phospholipase A1 activity) only if an ether linkage rather than an ester linkage is present at the sn-2 position. This hydrolysis is not stereospecific. Has calcium-independent phospholipase A2 and lysophospholipase activities in the presence of phosphoinositides. Has O-acyltransferase activity. Catalyzes the transfer of fatty acyl chains from phospholipids to a primary hydroxyl group of glycerol (sn-1 or sn-3), potentially contributing to monoacylglycerol synthesis (By similarity).

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).
