Metabolite Identification
Common NameKaempferol-3,7,4'-trimethyl ether
DescriptionKaempferol 3,7,4'-trimethyl ether belongs to the class of organic compounds known as 7-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, kaempferol 3,7,4'-trimethyl ether is considered to be a flavonoid lipid molecule. Kaempferol 3,7,4'-trimethyl ether is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
