[Thermodynamic and structural characteristics of partially denatured collagen].

Thermodynamic and structural parameters of partially denaturated collagen which had undergone denaturation of different degrees are measured. On the basis of comparative analysis of these data it is established that denaturation enthalpy and secondary structure degree are linearly linked. These investigations made it possible to determine special features of heat absorption curves as well. It is concluded that heat absorption at collagen denaturation must be followed by corresponding conformational alteration.
