Metabolite Identification
Common Name2,6-Pyridinedicarboxylic acid
Description2,6-Pyridinedicarboxylic acid, also known as 2,6-dicarboxypyridine or 2,6-dipicolinic acid, belongs to the class of organic compounds known as pyridinecarboxylic acids. Pyridinecarboxylic acids are compounds containing a pyridine ring bearing a carboxylic acid group. 2,6-Pyridinedicarboxylic 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 very few articles have been published on 2,6-Pyridinedicarboxylic acid.
