Metabolite Identification
Common NameEnhydrin
DescriptionAC1LASID belongs to the class of organic compounds known as germacranolides and derivatives. These are sesquiterpene lactones with a structure based on the germacranolide skeleton, characterized by a gamma lactone fused to a 1,7-dimethylcyclodec-1-ene moiety. AC1LASID is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Enhydrin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Enhydrin 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.
