Metabolite Identification
Common NamePurpurogallin
Descriptionpurpurogallin belongs to the class of organic compounds known as tropolones. Tropolones are compounds containing tropone ring with a hydroxyl group at ring position 2. Based on a literature review a small amount of articles have been published on purpurogallin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Purpurogallin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Purpurogallin 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.
