Common Name(2-{[(2r)-3-(hexadecanoyloxy)-2-[(9z,12z,15z)-octadeca-9,12,15-trienoyloxy]propyl phosphonato]oxy}ethyl)trimethylazanium
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. Within humans, PC(16:0/18:3(9Z,12Z,15Z)) participates in a number of enzymatic reactions. 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 mediated by the enzyme choline/ethanolaminephosphotransferase. A phosphatidylcholine 34:3 In which the acyl groups specified at positions 1 and 2 are palmitoyl and (9Z,12Z,15Z)-octadecatrienoyl (alpha-linolenoyl) respectively. (2-{[(2r)-3-(hexadecanoyloxy)-2-[(9z,12z,15z)-octadeca-9,12,15-trienoyloxy]propyl phosphonato]oxy}ethyl)trimethylazanium is found in Trypanosoma brucei. In humans, PC(16:0/18:3(9Z,12Z,15Z)) is involved in phosphatidylcholine biosynthesis.
