Metabolite Identification
Common NameN-Methyl-N-nitrosourea
DescriptionN-methyl-N-nitrosourea, also known as N-nitroso-N-methylurea or NMH, belongs to the class of organic compounds known as n-methylnitrosoureas. These are organonitrogen compounds with the general formula H3CN(N=O)R(N)=O (R = any atom). N-methyl-N-nitrosourea 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 significant number of articles have been published on N-methyl-N-nitrosourea. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-methyl-n-nitrosourea is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Methyl-N-nitrosourea 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.
