Chemical Information
FooDB Name7-Demethyltangeretin
Description7-demethyltangeretin is a member of the class of compounds known as 8-o-methylated flavonoids. 8-o-methylated flavonoids are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, 7-demethyltangeretin is considered to be a flavonoid lipid molecule. 7-demethyltangeretin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 7-demethyltangeretin can be found in mandarin orange (clementine, tangerine), which makes 7-demethyltangeretin a potential biomarker for the consumption of this food product.
