| Common Name | Betamethasone 17-benzoate |
|---|
| Description | Betamethasone 17-benzoate 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 Betamethasone 17-benzoate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Betamethasone 17-benzoate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Betamethasone 17-benzoate 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. |
