These are glycerophosphocholines in which the two free -OH are attached to one fatty acid each through an ester linkage. Thus, PC(20:3(8Z,11Z,14Z)/16:0) is considered to be a glycerophosphocholine lipid molecule. PC(20:3(8Z,11Z,14Z)/16:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(20:3(8Z,11Z,14Z)/16:0) exists in all eukaryotes, ranging from yeast to humans. 1-homo-g-linolenoyl-2-palmitoyl-sn-glycero-3-phosphocholine GPCho(36:3) PC(36:3) Lecithin Phosphatidylcholine(36:3) PC(20:3(8Z,11Z,14Z)/16:0) Phosphatidylcholine(20:3/16:0) PC(20:3/16:0) 1-(8Z,11Z,14Z-eicosatrienoyl)-2-hexadecanoyl-sn-glycero-3-phosphocholine GPCho(20:3/16:0) C44H82NO8P 784.0975 783.577805117 (2-{[(2R)-2-(hexadecanoyloxy)-3-[(8Z,11Z,14Z)-icosa-8,11,14-trienoyloxy]propyl phosphonato]oxy}ethyl)trimethylazanium lecithin CCCCCCCCCCCCCCCC(=O)O[C@]([H])(COC(=O)CCCCCC\C=C/C\C=C/C\C=C/CCCCC)COP([O-])(=O)OCC[N+](C)(C)C InChI=1S/C44H82NO8P/c1-6-8-10-12-14-16-18-20-21-22-23-25-26-28-30-32-34-36-43(46)50-40-42(41-52-54(48,49)51-39-38-45(3,4)5)53-44(47)37-35-33-31-29-27-24-19-17-15-13-11-9-7-2/h14,16,20-21,23,25,42H,6-13,15,17-19,22,24,26-41H2,1-5H3/b16-14-,21-20-,25-23-/t42-/m1/s1 YKSVDDIMSQYNID-YYQUKWHJSA-N belongs to the class of organic compounds known as phosphatidylcholines.
