Description | Methyl DL-cysteinate belongs to the class of organic compounds known as alpha amino acid esters. These are ester derivatives of alpha amino acids. Based on a literature review very few articles have been published on Methyl DL-cysteinate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Mecysteine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Mecysteine 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. |
