Because the lactose site splits glycosides with hydrophilic aglycons, whereas the phlorizin site preferentially splits glycosides with hydrophobic aglycons (1), these findings suggest that the lack of the HO-6 group in 4-galactosylxylose provides a more hydrophobic environment for enzyme binding, thereby restraining its interaction with the lactose site.
