Chemical Information
FooDB NameIsoxanthohumol
DescriptionIsoxanthohumol belongs to the class of organic compounds known as 8-prenylated flavanones. These are flavanones that features a C5-isoprenoid substituent at the 8-position. Thus, isoxanthohumol is considered to be a flavonoid lipid molecule. Isoxanthohumol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Isoxanthohumol is a bitter tasting compound. Isoxanthohumol is found, on average, in the highest concentration within beers. Isoxanthohumol has also been detected, but not quantified in, alcoholic beverages. This could make isoxanthohumol a potential biomarker for the consumption of these foods.
