Description (English)
Biochem/physiol Actions
An antioxidant flavonoid of plant origin; a free radical scavenger, preventing free radical-mediated damage in a variety of biological systems. For example, at physiological pH catechin suppressed DNA strand breaks by hydroxyl radicals. It has also been shown to prevent human plasma oxidation. It delayed the consumption of endogenous lipid-soluble antioxidants and inhibited lipid oxidation.
