Metabolite Identification
Common Name5-Methyl-1H-pyrazole-3-carboxylic acid
Description5-Methyl-1H-pyrazole-3-carboxylic acid belongs to the class of organic compounds known as pyrazole carboxylic acids and derivatives. These are heterocyclic compounds containing a pyrazole ring in which a hydrogen atom is replaced by a carboxylic acid group. 5-Methyl-1H-pyrazole-3-carboxylic 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 5-Methyl-1H-pyrazole-3-carboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 5-methyl-1h-pyrazole-3-carboxylic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5-Methyl-1H-pyrazole-3-carboxylic acid is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
