| Preferred Name | Flavonoid |
| Definitions |
One of a number of chemical compounds found in certain fruits, vegetables and seeds with antioxidant properties and potential antineoplastic properties. As polyphenolic, soluble plant pigments, flavonoids are usually subdivided into 5 subgroups flavonols, flavones, flavonones, flavan-3-ols, anthocyanidins. Although not considered essential nutrients, some flavonoids may be beneficial to health by strengthening and protecting blood vessels and connective tissue and acting as anti-inflammatory, antihistaminic, and antiviral agents. As antioxidants, some flavonoids may protect lipids from oxidative damage or retard the formation of cataracts. (NCI04)

| ALT_DEFINITION | A member of a group of substances found in many plants and plant-based foods. Flavonoids have shown antioxidant effects.
A class of polyphenols which are biogenetically derived from a phenylpropane (C6-C3 unit) and three C2 units to form a benzopyran with an additional phenyl group at C-2 (C6-C3-C6 unit). They consist of 15 carbons and vary by oxidation/hydroxylation, glycosidation, and other functional groups. Historically, the benzene ring is denoted 'A'-ring, the pyran ring 'C' ring, and the phenyl ring 'B'-ring. The numbering of the phenyl ring starts with 1' (""one prime"") at the carbon that is connected to the pyran ring, and follows along the phenyl ring with C-2', -3', -4', -5', and -6'.
