The docking results agree with these values. Niacinamide, Licorice, Kojic Acid Glow cream. What is Alpha-Arbutin? When the degree of inhibition (i) was calculated, a hyperbole was obtained (Fig 2A). By inhibiting tyrosinase activity, alpha-arbutin is known to reduce melanin production in the skin. Just like its sibling, alpha-arbutin is also a skin-brightening, depigmenting agent.

But, thanks to its high efficacy, ALPHA-ARBUTIN has gained wide acceptance and is rated highly by people from all walks of life. 0000003717 00000 n This equation agrees with the characteristics of the action of a competitive inhibitor: Vmax does not vary when the concentration of substrate, L-dopa or L-tyrosine, saturates the enzyme. All the assays were carried out with R = 0.042. The distance from the ortho carbon of the phenolic ring to the oxygen atom of the peroxide ion is shown in blue lines. 0000001129 00000 n Francisco Garcia-Canovas, Affiliation: Alpha arbutin, also called Hydroquinone -D-glucopyranoside, is a naturally occurring antioxidant and skin brightener that is naturally found in the bearberry plant.
