Metabolite Identification
Common NameEmamectin
DescriptionEmamectin belongs to the class of organic compounds known as aminoglycosides. These are molecules or a portion of a molecule composed of amino-modified sugars. Based on a literature review very few articles have been published on Emamectin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Emamectin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Emamectin 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.
