Chemical Information
FooDB NameIsocitric acid
DescriptionIsocitric acid, also known as isocitrate or i-cit, belongs to the class of organic compounds known as tricarboxylic acids and derivatives. These are carboxylic acids containing exactly three carboxyl groups. Isocitric acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Isocitric acid exists in all living species, ranging from bacteria to humans. Isocitric acid is found, on average, in the highest concentration within milk (cow). Isocitric acid has also been detected, but not quantified in, several different foods, such as apples, wild celeries, gooseberries, carrots, and soursops. This could make isocitric acid a potential biomarker for the consumption of these foods.
