Chemical Information

FooDB Name

Indole-beta-carboxylic acid

Description

Indole-3-carboxylic acid, also known as 3-carboxyindole or 3-indolecarboxylate, belongs to the class of organic compounds known as indolecarboxylic acids and derivatives. Indolecarboxylic acids and derivatives are compounds containing a carboxylic acid group (or a derivative thereof) linked to an indole. Indole-3-carboxylic acid is a weakly acidic compound (based on its pKa). Indole-3-carboxylic acid has been detected, but not quantified in, several different foods, such as barley, brussel sprouts, wakames, broccoli, and cucumbers. This could make indole-3-carboxylic acid a potential biomarker for the consumption of these foods.
