Metabolite Identification

Common Name

Methyl L-leucinate

Description

Methyl L-leucinate belongs to the class of organic compounds known as leucine and derivatives. Leucine and derivatives are compounds containing leucine or a derivative thereof resulting from reaction of leucine 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 Methyl L-leucinate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Methyl l-leucinate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Methyl L-leucinate 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.
