[Aperiodic structures, fractals, and low temperature heat capacity of biological macromolecules]

Low-molecular heat capacity of biological macromolecules has been analyzed in terms of modern conceptions of the physics of disordered systems and noncrystalline solids. It is shown that the fundamental thermodynamic features of these systems (amorphous and aperiodic structures, fractals polymers, etc.) are also inherent in biopolymers--proteins and nucleic acids, which gives a better insight into their structural-conformational and dynamic properties.
