Metabolite Identification
Common NamePC(20:0/14:1(9Z))
DescriptionPC(20:0/14:1(9Z)), also known as PC(34:1) 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(20:0/14:1(9Z)) is considered to be a glycerophosphocholine lipid molecule. PC(20:0/14:1(9Z)) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PC(20:0/14:1(9Z)) exists in all eukaryotes, ranging from yeast to humans.
