Membrane permeability-cell bio
... In addition to the lipid solubility of a molecule, its overall size and its molecular structure also influence its rate of penetration of the lipid bilayer. For example, since hydroxyl (-OH) groups can form hydrogen bonds with the water surrounding the cell, hydroxyl groups in a molecule will tend t ...
