Chemical Information
FooDB Name(+)-Dihydrowighteone
Description(+)-dihydrowighteone is a member of the class of compounds known as isoflavanones. Isoflavanones are polycyclic compounds containing an isoflavan skeleton which bears a ketone at position C4. Thus, (+)-dihydrowighteone is considered to be a flavonoid lipid molecule (+)-dihydrowighteone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). (+)-dihydrowighteone can be found in adzuki bean, which makes (+)-dihydrowighteone a potential biomarker for the consumption of this food product.
