Metabolite Identification
Common NameAmitrole
DescriptionAmitrole, also known as aminotriazole or 3-AT, belongs to the class of organic compounds known as triazoles. Triazoles are compounds containing a five-member aromatic ring of two carbon atoms and three nitrogen atoms. Amitrole exists in all living organisms, ranging from bacteria to humans. Based on a literature review a significant number of articles have been published on Amitrole. This compound has been identified in human blood as reported by (PMID: 31557052 ). Amitrole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Amitrole 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.
