摘要：
The ion-molecular association between inorganic ions and the charged groups of alanine zwitterion in biologically relevant aqueous salt solutions, namely NaCl(aq), KCl(aq), MgCl2(aq), and CaCl2(aq), has been investigated over a wide range of electrolyte concentration. The influence of salt concentration on the stability of the formed ion-molecular associates is analyzed. The structure of the formed aggregates and its dependence on salt concentration and chemical nature of the inorganic ion are discussed.
