Metabolite Identification
Common Name1H-Imidazole-1-acetic acid
Description1H-Imidazole-1-acetic acid, also known as 2-(imidazol-1-yl)acetate, belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. 1H-Imidazole-1-acetic acid is a very strong basic compound (based on its pKa). Outside of the human body, 1H-Imidazole-1-acetic acid has been detected, but not quantified in, mushrooms. This could make 1H-imidazole-1-acetic acid a potential biomarker for the consumption of these foods. An imidazolyl carboxylic acid that is acetic acid in which one of the methyl hydrogens is subsituted by an imidazol-1-yl group.
