The general form of Lewis acid-base reactions involves the formation of a covalent bond between a species that supplies an electron pair, which is called a Lewis base, and a species that can accept an electron pair, which is called a Lewis acid. In complexes of the formula [M(H2O)6]n...
These bond distances were greater than the covalent bond length of O-H (0.96 Å) and shorter than the Van der Waals distance between atom O and atom H (2.72 Å), which was within acceptable standards for a hydrogen bond [47]. The distances of Cl∙∙∙H were around 2.9 Å ...
The main methods used to form immobilized lipase are physical (surface) adsorption, covalent binding, encapsulation, cross-linking, and in situ synthesis shown in Figure 1. The appropriate method for the preparation of each conjugate should be carefully selected, as it can significantly affect the ...
