Metabolite Identification
Common NameN-Acetyl-S-trans,trans-farnesyl-L-cysteine
Description2-[(1-hydroxyethylidene)amino]-3-[(3,7,11-trimethyldodeca-2,6,10-trien-1-yl)sulfanyl]propanoic acid belongs to the class of organic compounds known as sesquiterpenoids. These are terpenes with three consecutive isoprene units. Based on a literature review very few articles have been published on 2-[(1-hydroxyethylidene)amino]-3-[(3,7,11-trimethyldodeca-2,6,10-trien-1-yl)sulfanyl]propanoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-acetyl-s-trans,trans-farnesyl-l-cysteine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Acetyl-S-trans,trans-farnesyl-L-cysteine 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.
