Metabolite Identification
Common Nametibolone
Descriptiontibolone belongs to the class of organic compounds known as oxosteroids. These are steroid derivatives carrying a C=O group attached to steroid skeleton. Based on a literature review a significant number of articles have been published on tibolone. This compound has been identified in human blood as reported by (PMID: 31557052 ). Tibolone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically tibolone 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.
