설명

일반 설명

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[1] such as grapes and bananas. It possesses an astringent and citrus flavor.[2]

애플리케이션

L-(+)-Tartaric acid has been used:

• in filter-sterilized synthetic grape juice for feast fermentation[3]
• in crystallization experiment[4]
• to test the influence of stereospecific interactions between stereoisomers of tartaric acid and proteins during crystallogenesis[5]

생화학적/생리학적 작용

L-(+)-Tartaric acid serves as a donor ligand for biological processes.[6] It is used as a food additive in candies and soft drinks to impart a sour taste.[2]
