Metabolite Identification
Common Name4-Hydroxybenzoic acid
Description4-Hydroxybenzoic acid, also known as p-hydroxybenzoate or 4-carboxyphenol, belongs to the class of organic compounds known as hydroxybenzoic acid derivatives. Hydroxybenzoic acid derivatives are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. 4-Hydroxybenzoic acid exists in all living species, ranging from bacteria to plants to humans. In humans, 4-hydroxybenzoic acid is involved in the ubiquinone biosynthesis pathway. 4-Hydroxybenzoic acid is a nutty and phenolic tasting compound. 4-Hydroxybenzoic acid is found, on average, in the highest concentration within a few different foods, such as red huckleberries (Vaccinium parvifolium), rabbiteye blueberries (Vaccinium virgatum), and corianders (Coriandrum sativum) and in a lower concentration in hyssops (Hyssopus officinalis), coffees (Coffea), and grapefruits (Citrus X paradisi). 4-Hydroxybenzoic acid has also been detected, but not quantified in, several different foods, such as barleys (Hordeum vulgare), gingers (Zingiber officinale), chickens (Gallus gallus), cowpeas (Vigna unguiculata), and dills (Anethum graveolens). This could make 4-hydroxybenzoic acid a potential biomarker for the consumption of these foods. 4-Hydroxybenzoic acid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on 4-Hydroxybenzoic acid.
