Chemical Information
FooDB NameQuercetin 3-O-methyl-ether
DescriptionQuercetin 3-methyl ether, also known as 3',4',5,7-tetrahydroxy-3-methoxyflavone or isorhamnetin, is a member of the class of compounds known as 3-o-methylated flavonoids. 3-o-methylated flavonoids are flavonoids with methoxy groups attached to the C3 atom of the flavonoid backbone. Thus, quercetin 3-methyl ether is considered to be a flavonoid lipid molecule. Quercetin 3-methyl ether is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Quercetin 3-methyl ether can be synthesized from quercetin. Quercetin 3-methyl ether can also be synthesized into 3-O-methylquercetin 7-O-beta-glucopyranosyl-4'-O-beta-D-glucopyranoside. Quercetin 3-methyl ether can be found in common bean, which makes quercetin 3-methyl ether a potential biomarker for the consumption of this food product.
