Metabolite Identification

Common Name

N-Methyl-L-histidine

Description

N-Methyl-L-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 a small amount of articles have been published on N-Methyl-L-histidine. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-methyl-l-histidine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Methyl-L-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.
