Metabolite Identification
Common Nameisochorismate
DescriptionIsochorismate, also known as isochorismic acid, belongs to beta hydroxy acids and derivatives class of compounds. Those are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom. Isochorismate is soluble (in water) and a weakly acidic compound (based on its pKa). Isochorismate can be found in a number of food items such as cucurbita (gourd), cherry tomato, chinese chestnut, and chinese water chestnut, which makes isochorismate a potential biomarker for the consumption of these food products. Isochorismate may be a unique E.coli metabolite.
