Metabolite Identification
Common NameCohumulone
DescriptionCohumulone belongs to the class of organic compounds known as tertiary alcohols. Tertiary alcohols are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R not H ). Cohumulone is a bitter tasting compound. Cohumulone has been detected, but not quantified in, alcoholic beverages and beer. This could make cohumulone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Cohumulone.
