Metabolite Identification
Common NameMethoxyphenylacetic acid
DescriptionMethoxyphenylacetic acid is a member of the class of compounds known as benzylethers. Benzylethers are aromatic ethers with the general formula ROCR' (R = alkyl, aryl; R'=benzene). Methoxyphenylacetic acid is soluble (in water) and a weakly acidic compound (based on its pKa). Methoxyphenylacetic acid can be found in olive, which makes methoxyphenylacetic acid a potential biomarker for the consumption of this food product.
