Molecular modeling is a powerful tool used in chemistry, biology, and materials science to study and predict the behavior of molecules and materials at the molecular level. By using computational methods, researchers can simulate and visualize the structure, properties, and interactions of molecules, proteins, and other biomolecules. This allows scientists to make predictions about molecular mechanisms, design new drugs, optimize chemical reactions, and understand complex biological processes. Molecular modeling techniques include molecular dynamics simulations, quantum chemistry calculations, and docking studies, among others.
