PyMOL 1.8.2.1 [60] and AutoDockTools4 [57,58] were used to edit and inspect the molecule structures and docked conformations. Alpha arbutin. A total oxygen consumption test was carried out in the presence of tert-butylcatechol and different concentrations of -arbutin (mM): a) 0, b) 5, c) 10 and d) 20. KM and kcat values were obtained fitting by non-linear regression (Table 2) the initial rate values vs. the concentration of substrate to the Eq 1 (Fig 7 and 7 Inset). . Copyright: 2017 Garcia-Jimenez et al. It is a natural skin lightener that helps with uneven skin tone and evens out skin tone.

Otherwise, the two are very similar in their effects and benefits. However, if 3-methyl-2-benzothiazolinone hydrazone hydrochloride hydrate is used, the o-quinone is attacked, so that it becomes an adduct, which can be oxidized by another molecule of o-quinone, generating o-diphenol in the medium.
