Metabolite Identification
Common NameReichstein's substance E
DescriptionReichstein's substance E, also known as 20 alpha-dihydrocortisol, belongs to the class of organic compounds known as 21-hydroxysteroids. These are steroids carrying a hydroxyl group at the 21-position of the steroid backbone. Based on a literature review a significant number of articles have been published on Reichstein's substance E. This compound has been identified in human blood as reported by (PMID: 31557052 ). Reichstein's substance e is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Reichstein's substance E 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.
