| Common Name | alpha-Monofluoromethyl histidine |
|---|
| Description | alpha-Monofluoromethyl histidine belongs to the class of organic compounds known as histidine and derivatives. Histidine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Based on a literature review very few articles have been published on alpha-Monofluoromethyl histidine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Alpha-monofluoromethyl histidine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically alpha-Monofluoromethyl histidine 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. |
