    tartaric acid

    Tartaric acid is a naturally occurring organic compound with the chemical formula C₄H₆O₆, widely found in fruits such as grapes and tamarind. It appears as white, odorless, water-soluble crystals and is considered one of the most important organic acids in the food, pharmaceutical, and chemical industries.

    In industry, it is especially used as a pH regulator, antioxidant, and stabilizer, and it is present in a variety of products, from beverages to effervescent medications.


    Structure of Tartaric Acid

    Tartaric acid contains two carboxylic acid groups (–COOH) and two hydroxyl groups (–OH). Its structure includes two chiral centers, meaning it can exist in different isomeric forms, including L(+), D(−), and DL (racemic) forms. The naturally occurring and biologically active form is L(+)-tartaric acid.
