oxyresveratrol + O2 tyrosinase hydroxylates the oxyresveratrol to an o-diphenol and oxidizes the latter to an o-quinone, which finally isomerizes to p-quinone. For these reactions to take place the presence of the Eox (oxy-tyrosinase) form is necessary, analysis of the catalytic mechanism, overview. The compound can also act as inhibitor of tyrosinase Agaricus bisporus ?
