Common Name | Pi-Methylimidazoleacetic acid |
---|
Description | Pi-Methylimidazoleacetic acid, also known as 1-methyl-imidazole-5-acetate or p-miaa, 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. Pi-Methylimidazoleacetic acid has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make pi-methylimidazoleacetic acid a potential biomarker for the consumption of these foods. Pi-Methylimidazoleacetic acid is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Pi-Methylimidazoleacetic acid. |
