Electrostatic interaction in biopolymer solutions investigated by NMR and laser light scattering

摘要

Abstract: In solution the surface of protein macromolecules is always charged and so the electrostatic interaction between the polar solvent and charged groups on the biopolymer surface is strong enough. It is of interest to consider three types of interaction: protein - protein, protein - contrion, protein - solvent. All of these interactions can change as static parameters of macromolecules solution. This paper deals with the most suitable methods for measurement of these parameters. The methods are NMR (nuclear magnetic resonance) and laser light scattering. !7
