Metabolite Identification
Common NameMethyl hexadecanoic acid
DescriptionMethyl hexadecanoic acid, also known as methyl palmitate or hexadecanoate methyl ester, belongs to the class of organic compounds known as fatty acid methyl esters. Fatty acid methyl esters are compounds containing a fatty acid that is esterified with a methyl group. They have the general structure RC(=O)OR', where R=fatty aliphatic tail or organyl group and R'=methyl group. Methyl hexadecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
