“…From the cosphere overlap model, we can predict numerous interactions happening in the mixed solution. , According to the cosphere model, different types of interactions possible in the ternary systems can be succinctly summarized in the following manner. Hydrophilic–hydrophilic interactions between the zwitterionic end part of two AAs. Hydrogen bond interactions among the hydrophilic sites (amine and carboxylic groups) of two AAs. Hydrophobic–hydrophobic interactions between the nonpolar parts of two AAs. Ion–ion interactions between the ionic part of the AA (NH 3 + and COO – ) and IL (EMIM + and PF 6 + ). Hydrophilic–hydrophilic interaction between the water or polar parts of AA and IL. Hydrophilic–hydrophobic interactions between the hydrophilic part of IL and the hydrophobic part of AAs. Hydrophobic–hydrophobic interactions between the hydrophobic part of AA and the hydrophobic parts (–C 2 H 5 and –CH 3 ) of [EMIM][PF 6 ]. …”

“…However, volumetric and transport properties of L-serine and L-threonine in binary and ternary aqueous solutions of other ILs were determined in several works [14][15][16][17][18][19][20][21]. We found that, the studied ionic liquid promoted remarkable changes in the solubility of the studied amino acid by reducing the pH of the solution [12].…”

The stability of amino acids in solutions containing electrolytes and the effect of ambient pH on their biological activity is one of the new research areas. In this research work, the volumetric and transport properties of ionic liquid (IL) aqueous solution with special performance of 1- (2-carboxyethyl) -3-methylimidazolium chloride ([HOOCEMIM][Cl]) were studied. The selected IL acts as an electrolyte with minimal toxicity and also allows the study of systems containing amino acids at acidic pH. In this work, the density, speed of sound and viscosity of binary and ternary solutions of IL in aqueous solution of amino acids in the structure of proteins, namely L-serine and L-threonine within IL molality range of (0.05, 0.07 and 0.09 mol kg-1) were measured at 298.15 K. From these quantities, apparent molar volume, limiting apparent molar volume, apparent molar isentropic compression, limiting apparent molar isentropic compression, transfer standard volumes for amino acids from water to the aqueous IL solutions and viscosity B-coefficients were calculated using the equations of Redlich–Meyer and Jones–Dole. Close examination of literature indicates that there is no data for water activity for solution of L-serine + H2O at 308.15 and 318.15 K. In this way water activity, osmotic coefficient and vapor pressure were measured and using the interaction parameters of Wilson, NRTL, NRF-NRTL and UNIQUAC models, activity coefficient values of L-serine calculated.
