Metabolite Identification
Common NameQuin-2 acetoxymethyl ester
DescriptionQuin-2 acetoxymethyl ester, also known as quin2-am, 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 a significant number of articles have been published on Quin-2 acetoxymethyl ester. This compound has been identified in human blood as reported by (PMID: 31557052 ). Quin-2 acetoxymethyl ester is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Quin-2 acetoxymethyl ester 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.
