Chemical Information
FooDB Name(1R,2S)-Isocitric acid
DescriptionD-threo-Isocitric acid, also known as isocitrate or isocitrIC ACID, belongs to the class of organic compounds known as tricarboxylic acids and derivatives. These are carboxylic acids containing exactly three carboxyl groups. D-threo-Isocitric acid is an extremely weak basic (essentially neutral) compound (based on its pKa). D-threo-Isocitric acid exists in all living species, ranging from bacteria to humans. Outside of the human body, D-threo-Isocitric acid has been detected, but not quantified in, several different foods, such as rubus (blackberry, raspberry), fruits, citrus, green beans, and common beans. This could make D-threo-isocitric acid a potential biomarker for the consumption of these foods. The D-threo-diastereomer of isocitric acid.
