Ligand-Protein Interaction Thermodynamics

Ligand-protein interaction thermodynamics characterises binding affinity through enthalpy and entropy contributions. Isothermal titration calorimetry directly measures binding heat. Fluorescence titration enables kinetics measurement. Dissociation constant determination quantitates binding strength. Temperature dependence characterises thermodynamic components.

Structure-activity relationship analysis correlates thermodynamics with efficacy. Drug design optimises thermodynamic favourability. Regulatory submissions justify molecular interactions. Clinical correlation validates thermodynamic predictions. Emerging computational methods improve thermodynamic calculations.
