| Common Name | N-(2-(Mercaptomethyl)-3-phenylbutanoyl)-L-alanine |
|---|
| Description | N-(2-(Mercaptomethyl)-3-phenylbutanoyl)-L-alanine belongs to the class of organic compounds known as n-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. Based on a literature review a small amount of articles have been published on N-(2-(Mercaptomethyl)-3-phenylbutanoyl)-L-alanine. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-(2-(mercaptomethyl)-3-phenylbutanoyl)-l-alanine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-(2-(Mercaptomethyl)-3-phenylbutanoyl)-L-alanine 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. |
