Chemical Information
FooDB NameGallic acid 3-O-gallate
Description3,4-dihydroxy-5-(3,4,5-trihydroxybenzoyloxy)benzoic acid, also known as gallic acid 3-monogallate or digallic acid, belongs to the class of organic compounds known as depsides and depsidones. These are polycyclic compounds that is either a polyphenolic compound composed of two or more monocyclic aromatic units linked by an ester bond (depside), or a compound containing the depsidone structure (depsidone). 3,4-dihydroxy-5-(3,4,5-trihydroxybenzoyloxy)benzoic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). 3,4-dihydroxy-5-(3,4,5-trihydroxybenzoyloxy)benzoic acid is found, on average, in the highest concentration within beers. 3,4-dihydroxy-5-(3,4,5-trihydroxybenzoyloxy)benzoic acid has also been detected, but not quantified in, evening primroses and tea. This could make 3,4-dihydroxy-5-(3,4,5-trihydroxybenzoyloxy)benzoic acid a potential biomarker for the consumption of these foods.
