Chemical Information
FooDB NameImidazoleacrylic acid
DescriptionTrans-urocanic acid, also known as 4-imidazoleacrylic acid or urocanate, belongs to imidazolyl carboxylic acids and derivatives class of compounds. Those are organic compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an imidazole ring. Trans-urocanic acid is soluble (in water) and a weakly acidic compound (based on its pKa). Trans-urocanic acid can be found in mung bean, which makes trans-urocanic acid a potential biomarker for the consumption of this food product. Trans-urocanic acid can be found primarily in most biofluids, including sweat, feces, blood, and urine, as well as in human liver and skin tissues. Trans-urocanic acid exists in all living organisms, ranging from bacteria to humans. In humans, trans-urocanic acid is involved in the histidine metabolism. Trans-urocanic acid is also involved in a couple of metabolic disorders, which include ammonia recycling and histidinemia.
