Discover a faster, simpler path to publishing in a high-quality journal. They used the met form of tyrosinase in contrast with this work where the oxy form was selected for docking purposes since the monophenolase activity resides in this form. Alpha arbutin can break down into carcinogenic chemicals if it comes from a synthetic source. Abstract. Alpha-Arbutin blocks epidermal melanin synthesis by inhibiting enzymatic oxidation of Tyrosine and Dopa. In this video, I will compare 2 Alpha Arbutin 2% + HA bottles. WHAT'S THE % OF ALPHA ARBUTIN? Hydroquinone is banned in Europe and Australia because it has dangerous bleaching properties. However, melanin causes the browning of fruits, vegetables, fungi and crustaceans, which harms their quality and organoleptic properties, reducing their commercial value [2].
