Common Name | N-Methyl-a-aminoisobutyric acid |
---|
Description | N-Methyl-a-aminoisobutyric acid, also known as 2-(methylamino)isobutyrate, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). N-Methyl-a-aminoisobutyric acid is a drug. N-Methyl-a-aminoisobutyric 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 N-methyl-a-aminoisobutyric acid a potential biomarker for the consumption of these foods. N-Methyl-a-aminoisobutyric 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 N-Methyl-a-aminoisobutyric acid. |
