Metabolite Identification
Common NameIsothymonin
DescriptionIsothymonin is a member of the class of compounds known as 7-o-methylated flavonoids. 7-o-methylated flavonoids are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, isothymonin is considered to be a flavonoid lipid molecule. Isothymonin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Isothymonin can be found in common thyme and spearmint, which makes isothymonin a potential biomarker for the consumption of these food products.
