Chemical Information
FooDB Name(S)-4',5,7-Trihydroxy-8-prenylflavanone
Description(s)-4',5,7-trihydroxy-8-prenylflavanone is a member of the class of compounds known as 8-prenylated flavanones. 8-prenylated flavanones are flavanones that features a C5-isoprenoid substituent at the 8-position. Thus, (s)-4',5,7-trihydroxy-8-prenylflavanone is considered to be a flavonoid lipid molecule (s)-4',5,7-trihydroxy-8-prenylflavanone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). (s)-4',5,7-trihydroxy-8-prenylflavanone can be found in beer, which makes (s)-4',5,7-trihydroxy-8-prenylflavanone a potential biomarker for the consumption of this food product.
