Metabolite Identification

Common Name

5,5-Dimethyl-1,3-cyclohexanedione

Description

5,5-dimethylcyclohexane-1,3-dione belongs to the class of organic compounds known as beta-diketones. These are organic compounds containing two keto groups separated by a single carbon atom. Based on a literature review very few articles have been published on 5,5-dimethylcyclohexane-1,3-dione. This compound has been identified in human blood as reported by (PMID: 31557052 ). 5,5-dimethyl-1,3-cyclohexanedione is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5,5-Dimethyl-1,3-cyclohexanedione 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.
