Living Cell Cytosol Stability to Segregation and   Freezing-Out:Thermodynamic aspect
  The cytosol state in living cell is treated as homogeneous phase equilibrium with a special feature: the pressure of one phase is positive and the pressure of the other is negative. From this point of view the cytosol is neither solution nor gel (or sol as a whole) regardless its components (water and dissolved substances). This is its unique capability for selecting, sorting and transporting reagents to the proper place of the living cell without a so-called "pipeline". To base this statement the theoretical investigation of the conditions of equilibrium and stability of the medium with alternative-sign pressure is carried out under using the thermodynamic laws and the Gibbs' equilibrium criterium.
