Abstract

Interaction of chemical fusogen n-nonyl bromide with a model membrane formed from phosphatidylcholine was studied using 2D-NMR spectra of heavy water and 31P-NMR proton decoupled spectra of the lipid phosphate group in multilamellar lipid dispersions. n-Nonyl bromide was found to influence the hydration layer of the model membrane. No participation of phosphatidylcholine molecules in non-bilayer configurations of the membrane was observed.
