Metabolite Identification
Common NameMethyl 3-hydroxyisovalerate
DescriptionMethyl 3-hydroxyisovalerate is a member of the class of 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 3-hydroxyisovalerate is soluble (in water) and an extremely weak acidic compound (based on its pKa). Methyl 3-hydroxyisovalerate can be found in bilberry and black walnut, which makes methyl 3-hydroxyisovalerate a potential biomarker for the consumption of these food products.
