Electrochemical impedance spectroscopy was used for the study of two-component lipid membranes. Phosphatidylcholine and ceramide were to be investigated, since they play an important biochemical role in cell membranes. The research on biolipid interaction was focused on quantitative description of processes that take part in a bilayer. Assumed models of interaction between amphiphilic molecules and the equilibria that take place there were described by mathematical equations for the studied system. The possibility of complex formation for two-component system forming bilayers was assumed that could explain the deviation from additivity rule. Equilibria were described by mathematical equations that were further verified experimentally. The determined values of parameters (stability constant, molecular area of complex, capacitance and conductance of the lipid membranes formed from molecules and complexes) were used for calculation of model curves. The comparison of model curves and experimental points verified the assumed model.

Free Energy Of Binding

We present a description of a bimolecular association in aqueous solution by dividing the free energy of binding into a number of terms representing ‘costs’ and ‘benefits'. Using data on the binding of cell-wall peptide analogues to vancomycin-group antibiotics, we have established an experimental basis for the adverse free energy of restricting internal rotations, the benefit in free energy from hydrophobic interactions and polar functional group interactions (amide-amide hydrogen bonds). Collating data from the literature on weak associations in non-polar solvents, a relation between the electrostatics of binding (enthalpy) and the dynamics (entropy) is presented. This provides an approximate, but useful, relation between the magnitude of the enthalpic barrier to dissociation for complexes in aqueous solution, and the cost in translational and rotational free energy of the reverse bimolecular association.
