Protocatechuic acid

3,4-dihydroxybenzoic acid

C7H6O4 (154.0266076)


Protocatechuic acid, also known as protocatechuate or 3,4-dihydroxybenzoate, 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. The enzyme protocatechuate 3,4-dioxygenase uses 3,4-dihydroxybenzoate and O2 to produce 3-carboxy-cis,cis-muconate. Protocatechuic acid is a drug. In the analogous hardening of the cockroach ootheca, the phenolic substance concerned is protocatechuic acid. Protocatechuic acid is a mild, balsamic, and phenolic tasting compound. Outside of the human body, protocatechuic acid is found, on average, in the highest concentration in a few different foods, such as garden onions, cocoa powders, and star anises and in a lower concentration in lentils, liquors, and red raspberries. Protocatechuic acid has also been detected, but not quantified in several different foods, such as cloud ear fungus, american pokeweeds, common mushrooms, fruits, and feijoa. This could make protocatechuic acid a potential biomarker for the consumption of these foods. It is also found in Allium cepa (17,540 ppm). It is a major metabolite of antioxidant polyphenols found in green tea. Similarly, PCA was reported to increase proliferation and inhibit apoptosis of neural stem cells. In vitro testing documented antioxidant and anti-inflammatory activity of PCA, while liver protection in vivo was measured by chemical markers and histological assessment. 3,4-dihydroxybenzoic acid, also known as protocatechuic acid or 4-carboxy-1,2-dihydroxybenzene, belongs to hydroxybenzoic acid derivatives class of compounds. Those are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. 3,4-dihydroxybenzoic acid is soluble (in water) and a weakly acidic compound (based on its pKa). 3,4-dihydroxybenzoic acid can be synthesized from benzoic acid. 3,4-dihydroxybenzoic acid is also a parent compound for other transformation products, including but not limited to, methyl 3,4-dihydroxybenzoate, ethyl 3,4-dihydroxybenzoate, and 1-(3,4-dihydroxybenzoyl)-beta-D-glucopyranose. 3,4-dihydroxybenzoic acid is a mild, balsamic, and phenolic tasting compound and can be found in a number of food items such as white mustard, grape wine, abalone, and asian pear, which makes 3,4-dihydroxybenzoic acid a potential biomarker for the consumption of these food products. 3,4-dihydroxybenzoic acid can be found primarily in blood, feces, and urine, as well as in human fibroblasts and testes tissues. 3,4-dihydroxybenzoic acid exists in all eukaryotes, ranging from yeast to humans. Protocatechuic acid (PCA) is a dihydroxybenzoic acid, a type of phenolic acid. It is a major metabolite of antioxidant polyphenols found in green tea. It has mixed effects on normal and cancer cells in in vitro and in vivo studies . 3,4-dihydroxybenzoic acid is a dihydroxybenzoic acid in which the hydroxy groups are located at positions 3 and 4. It has a role as a human xenobiotic metabolite, a plant metabolite, an antineoplastic agent, an EC 1.1.1.25 (shikimate dehydrogenase) inhibitor and an EC 1.14.11.2 (procollagen-proline dioxygenase) inhibitor. It is a member of catechols and a dihydroxybenzoic acid. It is functionally related to a benzoic acid. It is a conjugate acid of a 3,4-dihydroxybenzoate. 3,4-Dihydroxybenzoic acid is a natural product found in Visnea mocanera, Amomum subulatum, and other organisms with data available. Protocatechuic acid is a metabolite found in or produced by Saccharomyces cerevisiae. See also: Black Cohosh (part of); Vaccinium myrtillus Leaf (part of); Menyanthes trifoliata leaf (part of) ...

Shikimic acid, more commonly known as its anionic form shikimate, is a cyclohexene, a cyclitol and a cyclohexanecarboxylic acid. It is an important biochemical intermediate in plants and microorganisms. Its name comes from the Japanese flower shikimi (the Japanese star anise, Illicium anisatum), from which it was first isolated. Shikimic acid is a precursor for: the aromatic amino acids phenylalanine and tyrosine; indole, indole derivatives and tryptophan; many alkaloids and other aromatic metabolites; tannins; and lignin. In pharmaceutical industry, shikimic acid from chinese star anise is used as a base material for production of Tamiflu (oseltamivir). Although shikimic acid is present in most autotrophic organisms, it is a biosynthetic intermediate and generally found in very low concentrations. A cyclohexenecarboxylic acid that is cyclohex-1-ene-1-carboxylic acid substituted by hydroxy groups at positions 3, 4 and 5 (the 3R,4S,5R stereoisomer).
