Metabolite Identification
Common Name2-Aminoheptanedioic acid
Description2-Aminoheptanedioic acid, also known as alpha-aminopimelic acid or a-aminopimelate, 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). 2-Aminoheptanedioic acid has been detected, but not quantified in, beverages and fruits. This could make 2-aminoheptanedioic acid a potential biomarker for the consumption of these foods. 2-Aminoheptanedioic 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 small amount of articles have been published on 2-Aminoheptanedioic acid.
