NMR study of cholesterol complexes with glycyrrhizic acid

摘要

Nuclear magnetic resonance (NMR) relaxation technique was applied to study the interaction of cholesterol with natural complexant - glycyrrhizic acid. Stoichiometry, stability constants and thermodynamic parameters of the complex have been measured. We propose that the complexation with glycyrrhizic acid could be an effective approach to regulate the cholesterol level inside and outside of cage membranes.
