Description | Isorhamnetin, also known as 3-methylquercetin, belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, isorhamnetin is considered to be a flavonoid. Isorhamnetin exists in all eukaryotes, ranging from yeast to plants to humans. Isorhamnetin is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction.
