In this paper, a statistical model introducing analytical expressions of x dependent quantum statistical parton distributions is presented to explore proton and neutron structures. A merely theoretical maximum entropy method is applied to obtain thermodynamical variables determining parton distributions accurately. This study provides considering proton and neutron isospin asymmetry in order to improve the consistency of the framework achievements with the experimental results. The presented approach is extended to evaluate modified neutron structure in an n-p state. Also, the uniqueness of gluon distribution in proton and neutron is surveyed for both cases of lonely nucleon and n-p system. Eventually, the predicted unpolarized structure functions and the spin structure functions, only based on the maximum entropy method, are compared to CERN, HERMES, SLAC and the other data sets. Finally, the correlation of the obtained distributions with the experimental observations confirms the proposed statistical model.
