Alcohol induced structural and dynamic changes in β-lactoglobulin in aqueous solution: A neutron scattering study

► Structural and dynamic properties of β-lactoglobulin in aqueous alcohol solutions have been revealed. ► Protein aggregation state and internal motions depend on alcohol concentration. ► Internal motions are more sensitive to aggregation than the structure. ► Structure/dynamics studies are necessary to obtain a complete picture of a molecular process.
