ABSTRACT A summary of a theoretical study of the dependence of four conformational properties namely dimensions, dipole moment, square optical anisotropy and Kerr constant on the secondary and tertiary structures of polyglycine is presented. The results show the convenience of using polyglycine as a simple model for polypeptides and proteins as well as the possibilities of the four magnitudes, especially Kerr constant to be used as a probe on the conformational study of polypeptides.
