Metabolite Identification

Common Name

Karahana lactone

Description

Karahana lactone belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. Karahana lactone has been detected, but not quantified in, alcoholic beverages. This could make karahana lactone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Karahana lactone.
