Metabolite Identification
Common Name7-(1-Imidazolyl)heptanoic acid
Description7-(1-Imidazolyl)heptanoic acid, also known as 1-(7-carboxyheptyl)imidazole, 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. Based on a literature review very few articles have been published on 7-(1-Imidazolyl)heptanoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 7-(1-imidazolyl)heptanoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 7-(1-Imidazolyl)heptanoic 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.
