Electrical Potential at Biomolecular Interfaces

Biochemical and biophysical activity often occurs at the interfaces of biomolecules and various types of assemblies of such molecules/ Several biomolecular interfaces considered are listed in Table 13. [Pg.39]

In order to elucidate the physicochemical properties of such a biological membrane interface, several model membrane systems (lipid monolayer, lipid bilayers, and protein-incorporated lipid model membrane systems) which mimic biological membrane interfaces have also been studied.In particular, many properties at the membrane surface are intimately related to the electrical potential originating from the fixed charge or electrical polarization of the membrane constitutents.
