l tartaric acid

L-Tartaric acid ((2R,3R)-(+)-Tartaric acid) occurs naturally in many plants, particularly grapes and tamarinds, and is one of the main acids found in wine. It is used as an antioxidant. Salts of tartaric acid are known as tartrates. L-Tartaric acid is a muscle toxin, which works by inhibiting the production of malic acid, and in high doses causes paralysis and death.

Tartaric acid disodium dihydrate (Disodium L-(＋)-Tartrate Dihydrate) is commonly used as a buffer in molecular biology and cell culture.Tartaric acid disodium dihydrate is an acid phosphatase inhibitor that increases the probability of colchicine binding to tubulin1.

DL-Tartaric acid is a non-racemic mixture of L- and D-tartaric acid with antioxidant activity. By activating the AMP-activated protein kinase signaling pathway, it improves experimental non-alcoholic fatty liver disease.
