Metabolite Identification
Common NameEthylestrenol
DescriptionEthylnandrol, also known as ethylestrenol or maxibolin, belongs to the class of organic compounds known as pregnane steroids. These are steroids with a structure based on the 21-carbon pregnane skeleton. Based on a literature review very few articles have been published on Ethylnandrol. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ethylestrenol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ethylestrenol 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.
