MBTH traps the enzyme-generated o-quinones to render a stable MBTH-quinone adduct with a high molar absorptivity. The met and oxy forms of tyrosinase were built by a slight modification of the binuclear copper-binding site as previously described [56]. When you have less tyrosine, you will have a more even complexion overall. These observations suggest that the compounds are alternative substrates of the enzyme. Just like its sibling, alpha-arbutin is also a skin-brightening, depigmenting agent.
