1.0 2016-10-03 17:16:58 UTC 2020-06-04 20:05:09 UTC BMDB0008243 BMDB08243 PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)), also known as gpcho(18:4/20:2) or phosphatidylcholine(38:6), 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(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) is considered to be a glycerophosphocholine lipid molecule. PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) exists in all eukaryotes, ranging from yeast to humans. PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) can be biosynthesized from S-adenosylmethionine and pe-nme2(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)); which is catalyzed by the enzyme phosphatidylethanolamine N-methyltransferase. Furthermore, Cytidine monophosphate and PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) can be biosynthesized from CDP-choline and DG(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. Finally, PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) and L-serine can be converted into choline and PS(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) through its interaction with the enzyme phosphatidylserine synthase. In cattle, PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) is involved in a couple of metabolic pathways, which include phosphatidylcholine biosynthesis PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) pathway and phosphatidylethanolamine biosynthesis pe(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) pathway. 1-Stearidonoyl-2-eicosadienoyl-sn-glycero-3-phosphocholine GPCho(18:4/20:2) Phosphatidylcholine(38:6) Lecithin GPCho(38:6) Phosphatidylcholine(18:4/20:2) PC(18:4/20:2) 1-(6Z,9Z,12Z,15Z-Octadecatetraenoyl)-2-(11Z,14Z-eicosadienoyl)-sn-glycero-3-phosphocholine PC(38:6) PC(18:4(6Z,9Z,12Z,15Z)/20:2(11Z,14Z)) C46H80NO8P 806.1031 805.562155053 (2-{[(2R)-2-[(11Z,14Z)-icosa-11,14-dienoyloxy]-3-[(6Z,9Z,12Z,15Z)-octadeca-6,9,12,15-tetraenoyloxy]propyl phosphono]oxy}ethyl)trimethylazanium (2-{[(2R)-2-[(11Z,14Z)-icosa-11,14-dienoyloxy]-3-[(6Z,9Z,12Z,15Z)-octadeca-6,9,12,15-tetraenoyloxy]propyl phosphono]oxy}ethyl)trimethylazanium [H][C@@](COC(=O)CCCC\C=C/C\C=C/C\C=C/C\C=C/CC)(COP([O-])(=O)OCC[N+](C)(C)C)OC(=O)CCCCCCCCC\C=C/C\C=C/CCCCC InChI=1S/C46H80NO8P/c1-6-8-10-12-14-16-18-20-22-23-25-27-29-31-33-35-37-39-46(49)55-44(43-54-56(50,51)53-41-40-47(3,4)5)42-52-45(48)38-36-34-32-30-28-26-24-21-19-17-15-13-11-9-7-2/h9,11,14-17,20-22,24,28,30,44H,6-8,10,12-13,18-19,23,25-27,29,31-43H2,1-5H3/b11-9-,16-14-,17-15-,22-20-,24-21-,30-28-/t44-/m1/s1 RJBUKRKXNJFIDS-MXQFTRAWSA-N belongs to the class of organic compounds known as phosphatidylcholines.
