Metabolite Identification
Common NameTrans-urocanate
Descriptionurocanic acid, also known as urocanate, belongs to the class of organic compounds known as imidazolyl carboxylic acids and derivatives. These are organic compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an imidazole ring. An alpha,beta-unsaturated monocarboxylic acid that is prop-2-enoic acid substituted by a 1H-imidazol-4-yl group at position 3. urocanic acid is a very strong basic compound (based on its pKa).
