It seems appropriate that a conference on protein-protein interactions should include an introductory discussion on the subject of molecular forces. The nature of molecular forces is universal and our understanding of such forces in small molecules, particularly those which have the same groupings of atoms as the side groups and the backbone of proteins, promotes our understanding of the forces within and between protein molecules. The more we understand molecular forces in proteins, the better will be our understanding of the structure of protein molecules and of their complexes, their interaction with substrates and other molecules, and ultimately the detailed quantitative relation between molecular structure and biological function in living systems.
