Chemical Information
FooDB Name3,4-Dihydroxyphenylacetic acid
Description3,4-Dihydroxybenzeneacetic acid, also known as 3,4-dihydroxyphenyl acetate or dopacetic acid, belongs to the class of organic compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. 3,4-Dihydroxybenzeneacetic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). 3,4-Dihydroxybenzeneacetic acid exists in all living organisms, ranging from bacteria to humans. 3,4-Dihydroxybenzeneacetic acid is found, on average, in the highest concentration within olives and beers. 3,4-Dihydroxybenzeneacetic acid has also been detected, but not quantified in, several different foods, such as alfalfa, caraway, sunflowers, oriental wheats, and hazelnuts. This could make 3,4-dihydroxybenzeneacetic acid a potential biomarker for the consumption of these foods.
