We propose the conformon as a quantum of local conformational
change for energy transfer in alpha-helical proteins. The underlying mechanism of
interaction between the quantum of excitation and the conformational degrees
of freedom is nonlinear and leads to solitary wave packets of conformational
energy. The phenomenon is specific to alpha-helices and not to beta-sheets in proteins
due to the three strands of hydrogen bonds constituting the alpha-helical backbone.
