A large number of experimental results have shown that macromolelcules in solution give rise to ordered (thyxotropic) structures, a noticeable role being played by a dynamic correlation. In the present paper we develop a semi-phenomenological model that can be solved analytically. The model is able to describe in a quantitative way both structural and dynamical properties of a thyxotropic solution. A careful experimental investigation is also carried out and the experimental results are compared to the theoretical prediction. In such a way the relevant parameters implied in the structure can be evaluated. Some implications concerning energy exchanges between proteins and the thermal bath are discussed

Abstract
A large number of experimental results have shown that macromolelcules in solution give rise to ordered (thyxotropic) structures, a noticeable role being played by a dynamic correlation. In the present paper we develop a semi-phenomenological model that can be solved analytically. The model is able to describe in a quantitative way both structural and dynamical properties of a thyxotropic solution. A careful experimental investigation is also carried out and the experimental results are compared to the theoretical prediction. In such a way the relevant parameters implied in the structure can be evaluated. Some implications concerning energy exchanges between proteins and the thermal bath are discussedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
