Applications of molecular graphics to biophysics are reviewed. Biological macromolecules are different from inorganic molecules or synthesized polymers, in that they own their biological information on their tertiary structures. Molecular Graphics are the powerful techiniques, which visualize such information on their tertiary structures to give us deeper understandings to them. There have been four kinds of applications; 1) visualizing their analyzed tertiary structures, 2) assisting analyses of their tertiary structures, 3) predicting their structures, especially those with drug ligands and 4) visualizing their physical, chemical and biological properties and information together with their tertiary structures. Several examples being applied in the field of biophysics are introduced.
