Metabolite Identification
Common Name20,26-Dihydroxyecdysone
Description20,26-Dihydroxyecdysone belongs to the class of organic compounds known as hydroxy bile acids, alcohols and derivatives. These are bile acids, alcohols or derivatives bearing at least hydroxyl group. Based on a literature review a significant number of articles have been published on 20,26-Dihydroxyecdysone. This compound has been identified in human blood as reported by (PMID: 31557052 ). 20,26-dihydroxyecdysone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 20,26-Dihydroxyecdysone 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.
