Metabolite Identification
Common Name2-Hydroxy-3-(1H-imidazol-5-yl)propanoic acid
Description3-(imidazol-5-yl)lactic acid, also known as imidazole lactate or a-hydroxy-1H-imidazolepropanoate, 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. 3-(imidazol-5-yl)lactic acid exists in all living organisms, ranging from bacteria to humans. 3-(imidazol-5-yl)lactic acid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a small amount of articles have been published on 3-(imidazol-5-yl)lactic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-hydroxy-3-(1h-imidazol-5-yl)propanoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Hydroxy-3-(1H-imidazol-5-yl)propanoic 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.
