Metabolite Identification
Common NameFormononetin
DescriptionFormononetin, also known as biochanin b, belongs to the class of organic compounds known as 4'-o-methylisoflavones. These are isoflavones with methoxy groups attached to the C4' atom of the isoflavone backbone. Thus, formononetin is considered to be a flavonoid lipid molecule. Formononetin exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule.
