General description
Tartaric acid is a dicarboxylic acid and occurs as two enantiomers and an achiral meso compound. The L-(+)-tartaric acid is extensively found in nature. It is an acid present in fruits such as grapes and bananas. It possesses an astringent and citrus flavor.
Application
L-(+)-Tartaric acid has been used:
- in filter-sterilized synthetic grape juice for feast fermentation
- in crystallization experiment
- to test the influence of stereospecific interactions between stereoisomers of tartaric acid and proteins during crystallogenesis
Biochem/physiol Actions
L-(+)-Tartaric acid serves as a donor ligand for biological processes. It is used as a food additive in candies and soft drinks to impart a sour taste.
