Tartaric acid is a molecule that demonstrates properties of optical activity, where a molecule can cause the rotation of plane-polarized light. Tartaric acid exists in four forms (isomers are molecular rearrangements of the same atoms), each of which affects plane-polarized light differently.

—Two molecules in which the number of atoms and the types of atoms are identical, but their arrangement in space is different, resulting in different chemical and physical properties. Isomers based on chiral centers (such as tartaric acid) are sometimes called stereoisomers.

Tartaric acids can be synthesized from maleic acids or fumaric acids by reaction with aqueous potassium permanganate. The various isomeric forms differ in such physical properties as boiling point. Tartaric acid is used chiefly in the form of its salts, e.g., cream of tartar and Rochelle salt .

Three stereoisomeric forms of tartaric acid exist: (1) dextrorotatory tartaric acid (d-tartaric acid) found in grapes and several ... Study of the crystallographic, chemical, and optical properties of the tartaric acids by French chemist and microbiologist Louis Pasteur laid the basis for modern ideas of stereoisomerism.
