Common Name | 2,6-Dihydroxybenzoic acid |
---|
Description | 2,6-Dihydroxybenzoic acid, also known as 6-hydroxysalicylic acid or gamma-resorcylic acid, belongs to the class of organic compounds known as salicylic acids. These are ortho-hydroxylated benzoic acids. 2,6-Dihydroxybenzoic acid is found, on average, in the highest concentration within beer and olives (Olea europaea). 2,6-Dihydroxybenzoic acid has also been detected, but not quantified in, strawberries (Fragaria X ananassa). This could make 2,6-dihydroxybenzoic acid a potential biomarker for the consumption of these foods. 2,6-Dihydroxybenzoic acid is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 2,6-Dihydroxybenzoic acid. |
