The compound occurs naturally in many plants, particularly in grapes, bananas, and tamarinds. It is also one of the main acids found in wine. Tartaric acid can be added to food when a sour taste is desired. It is also used as an antioxidant. Salts of tartaric acid are known as tartarates. The chemical is a dihydroxy derivative of succinic acid. Tartaric acid is found in cream of tartar and baking powder.
The chemical compound is used in silvering mirrors, tanning leather, and in Rochelle Salt. In medical analysis, tartaric acid is used to make solutions for the determination of glucose.
With one week lead-time, TCC ships Tartaric acid in 25kg bags, and 1,kg supersacks throughout the continental United States. Please call for details. Tartaric acid is available in 25kg bags and 1,kg supersacks. In general, where biological molecules have optical isomers, only one of the isomers or forms will be active biologically. The other will be unaffected by the enzymes in living cells.
The meso form of the molecule is not affected by polarized light. The fourth form — the DL mixture, is not a single molecule, but a mixture of equal amounts of D and L isomers. It does not rotate polarized light like the meso form because the rotation of light by the D and L forms is equal in amount but opposite in direction. It is possible to separate the DL mixture into the two isomers, each of which does rotate light. In the s, Louis Pasteur determined that each of the two isomers of tartaric acid rotated light in opposite directions, and the meso form was inactive in this respect.
He also separated by hand, crystals of the racemic mixture to show that it was made of equal amounts of the D and L forms, making it different than the meso form of tartaric acid. Tartaric acid is found in cream of tartar, which is used in making candies and frostings for cakes.
Tartaric acid is also used in baking powder where it serves as the source of acid that reacts with sodium bicarbonate baking soda. Tartaric acid is used in silvering mirrors, tanning leather, and in the making of Rochelle Salt, which is sometimes used as a laxative. Blue prints are made with ferric tartarte as the source of the blue ink. Download our latest paper. Tartaric Acid What is Tartaric Acid?
