Metabolite Identification

Common Name

3,5,5-Trimethyl-1,2-cyclopentanedione

Description

3,5,5-Trimethyl-1,2-cyclopentanedione belongs to the class of organic compounds known as cyclic ketones. These are organic compounds containing a ketone that is conjugated to a cyclic moiety. 3,5,5-Trimethyl-1,2-cyclopentanedione has been detected, but not quantified in, a few different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make 3,5,5-trimethyl-1,2-cyclopentanedione a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3,5,5-Trimethyl-1,2-cyclopentanedione.
