Metabolite Identification
Common Namealpha-Methyl-m-tyrosine
Descriptionalpha-Methyl-m-tyrosine belongs to the class of organic compounds known as phenylpropanoic acids. Phenylpropanoic acids are compounds with a structure containing a benzene ring conjugated to a propanoic acid. Based on a literature review very few articles have been published on alpha-Methyl-m-tyrosine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Alpha-methyl-m-tyrosine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically alpha-Methyl-m-tyrosine 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.
