Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, 3,7,3',4'-tetrahydroxyflavone is considered to be a flavonoid lipid molecule. 3,7,3',4'-tetrahydroxyflavone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 3,7,3',4'-tetrahydroxyflavone is a bitter tasting compound found in soy bean, which makes 3,7,3',4'-tetrahydroxyflavone a potential biomarker for the consumption of this food product.
