A thermostatistical approach to protein structures

Abstract

In this study, the relation between the additional heat capacities of proteins have been obtained. The expressions for the increments of enthalpy Delta H, entropy Delta S and Gibbs energy Delta G which are encountered in the dissolving of the proteins in water, have been calculated. Partition functions of proteins are related to the macrothermodynamical quantities with the help of free energies. In order to endeavour the structure of the proteins, the theoretical calculations of thermostatistical mechanics are fitted to the data of experimental results. (c) 2007 Elsevier B.V.
