  In this study, internal energy (U), electric field (E) and particle number
(N) which specify the system quantities i.e. thermodynamical quantities for the
proteins. In the frame of thermodynamical formalism, the relation between the
heat capacity at effective field and the heat capacity at total dipole moment
and the relations for the increment of enthalpy, entropy and Gibbs energy which
come out in the dissolving of the proteins in water have been obtained. By
thinking about the present system being in the heat bath the canonical
distribution function, by considering the system in heat and electric field
bath the macro canonical distribution function and once more by taking the
system in heat and particle number bath the macro canonical distribution
function have been calculated. Partition functions have been related to the
macro canonical quantities with the help of the free energy. Understanding the
structure of the proteins have been endeavoured by fitting the theoretical
calculations to the curves of experimental results.
