...pt chemical bonds in other molecules -- individual atoms of a protein must be aligned just so if they are to function properly. Consequently, there is a direct relationship between a protein's shape and its function. The study of amyloids is complicated by the fact that the shape of very few proteins is kn...World's top theoretical physicists converge to consider 'future of physics'
