Metabolite Identification
Common NameImidazoleacetic acid
DescriptionImidazoleacetic acid, also known as 4(5)-imidazoleacetate or imac, 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. Imidazoleacetic acid is possibly soluble (in water) and a very strong basic compound (based on its pKa). Imidazoleacetic acid exists in all living organisms, ranging from bacteria to humans. Imidazoleacetic acid can be biosynthesized from imidazole-4-acetaldehyde through the action of the enzyme aldehyde dehydrogenase, mitochondrial. In cattle, imidazoleacetic acid is involved in the metabolic pathway called the histidine metabolism pathway. Imidazoleacetic acid is a potentially toxic compound.
