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
