| Description | Trans-caftaric acid belongs to the class of organic compounds known as coumaric acids and derivatives. These are aromatic compounds containing Aromatic compounds containing a cinnamic acid moiety (or a derivative thereof) hydroxylated at the C2 (ortho-), C3 (meta-), or C4 (para-) carbon atom of the benzene ring. Intact trans-caftaric acid was detected in rat plasma along with its O-methylated derivative trans-fertaric acid. Trans-caftaric acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Grape reaction product (2-S glutathionyl caftaric acid) is an oxidation compound produced from caftaric acid and found in wine. Caftaric acid is a non-flavanoid phenolic compound. Malvidin 3-glucoside alone is not oxidized in the presence of grape polyphenol oxidase (PPO), whereas it is degraded in the presence of a crude grape PPO extract and of caftaric acid, forming anthocyanidin-caftaric acid adducts. Aside from wine, it is abundantly present in raisins. Caftaric acid has a good bioavailability when fed in rats. Winemakers measure caftaric acid levels as their primary method to estimate the oxidation levels that a wine has undergone. For example, press wines, which undergo a high degree of oxidation, will have little to no caftaric acid. Caffeic acid is susceptible to chemical oxidation, and subsequent redox reactions involving caffeic acid can contribute to wine browning over time, and the straw-gold color that can develop in some white wines after bottling. 2-{[3-(3,4-dihydroxyphenyl)prop-2-enoyl]oxy}-3-hydroxybutanedioic acid is found in Vitis vinifera. It is an esterified phenolic acid, composed of caffeic acid, a hydroxycinnamate produced by plants, and tartaric acid, the principal organic acid found in grape berries. |
