Chemical Information
FooDB NameMethyl gallate
DescriptionMethyl gallate, also known as methyl 3 or methyl galloic acid, is a member of the class of compounds known as galloyl esters. Galloyl esters are organic compounds that contain an ester derivative of 3,4,5-trihydroxybenzoic acid. Methyl gallate is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Methyl gallate can be found in peach and pomegranate, which makes methyl gallate a potential biomarker for the consumption of these food products. Methyl gallate is a phenolic compound. It is the methyl ester of gallic acid .
