Chemical Information
FooDB Name2',4',5,7-Tetrahydroxy-8-prenylisoflavone
Description2',4',5,7-Tetrahydroxy-8-prenylisoflavone, also known as 2,3-dehydrokievitone, belongs to the class of organic compounds known as isoflavones. These are polycyclic compounds containing a 2-isoflavene skeleton which bears a ketone group at the C4 carbon atom. Thus, 2',4',5,7-tetrahydroxy-8-prenylisoflavone is considered to be a flavonoid lipid molecule. 2',4',5,7-Tetrahydroxy-8-prenylisoflavone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 2',4',5,7-Tetrahydroxy-8-prenylisoflavone has been detected, but not quantified in, several different foods, such as lima beans, green beans, common beans, yellow wax beans, and mung beans. This could make 2',4',5,7-tetrahydroxy-8-prenylisoflavone a potential biomarker for the consumption of these foods.
