• is not only difficult but is also defective in principle. This dynamic continuum has also been depicted by an elaborate computational simulation report by Fu et al. in 2021 [41] which was a major follow-up of the work by Crich and co-workers in 2018 [29]. In general cases, the axial glycosides also

• oxidation current can be considered as a decrease in the diffusion coefficient of the hydrogen bond complex; thus, we attempted to reproduce the CV pattern by computational simulation (Figures S1 and S2 in Supporting Information File 1) [16]. The results indicated that an excessively small diffusion

• preferential stabilisation of the TS in the wild-type relative to a Tyr69Phe mutant is achieved by means of a short, strong hydrogen bond from Tyr69 to the enzymic nucleophile. Catalysis is TS molecular recognition, and computational simulation may provide valuable insight into the causes of preferential
