text: The structural features of green tea catechins that significantly contribute to their biological action are the number and positions of the hydroxyl groups (or their substitutents) on the rings, which determine their ability to interact with biological matter through hydrogen bonding, or electron and hydrogen transfer processes within their antioxidant activities, and by the presence/absence of the galloyl moiety, which clearly distinguishes EGC from the other three catechins.
