We determined spectrophotometrically the monophenolase and diphenolase activities of tyrosinase acting on substrates that originate o-quinones and do not evolve with a defined stoichiometry. Group of Molecular Interactions in Membranes, Department of Biochemistry and Molecular Biology-A, University of Murcia, Espinardo, Murcia, Spain. Arbutin is therefore used as a skin-lightening agent. It is often considered a safer alternative to something called hydroquinone. This complex could evolve in two ways: by oxidizing the originated o-diphenol to o-quinone and deoxy-tyrosinase, or by delivering the o-diphenol and met-tyrosinase to the medium, which would produce the self-activation of the system. Experiments with the diphenolase activity show similar inhibition (Fig 3A Inset and 3B Inset for and -arbutin, respectively). It contains beneficial compounds that regulate skin's pigment. -arbutin has a lower Michaelis constant than -arbutin (Table 2). Kinetic constants for the apparent inhibition of -arbutin and -arbutin on tyrosinase. The alpha arbutin serum readily absorbs into the skin and also helps to reduce tanning. Topical cosmetic compositions comprising alpha arbutin Note that big difference between the apparent inhibition values, as is shown in Table 1. "They differ in structure and properties." The 2 main reasons to use alpha arbutin are for skin lightening and covering blemishes from skin discoloration. Alpha-Arbutin COA.
