What is the source of tartaric acid?

Answer 1

Tartaric acid is found in many plants, e.g., grapes; this natural acid is chiefly the dextrorotatory d-tartaric acid, called also d-2,3-dihydroxysuccinic acid or l-2,3-dihydroxybutanedioic acid. This form can be partially converted to the others by heating it with an aqueous alkali, e.g., potassium hydroxide. Tartaric acids can be synthesized from maleic acids or fumaric acids by reaction with aqueous potassium permanganate.
