“…As a result, the V φ 0 values remain uninfluenced by its own interaction of l -Asn and l -Gln molecules (solute–solute) and it is only a compute of the solute-co solvent interaction. The limiting apparent molar volume ( V φ 0 ) values are represented in Tables and which had many similarities with the earlier literature outcomes. , …”

In order to comprehend the various properties of two amino acids (AAs), Lasparagine and L-glutamine, we have studied a number of physicochemical parameters, including density (ρ), absolute viscosity (η), refractive index (n D ), conductivity (σ), and surface tension (γ) in the aqueous solution of an ionic liquid (IL), benzyl-tributyl ammonium chloride (BTBAC), in (0.001, 0.003, and 0.005) molalities and five temperatures of 293.15, 298.15, 303.15, 308.15, and 313.15 K at atmospheric pressure of 0.1 MPa. Limiting apparent molar volumes (V φ 0 ) derived from the Masson equation, coefficient of viscosity (B) from the Jones−Doles equation, and limiting molar refraction (R M 0 ) from the Lorentz−Lorenz equation are applied to criticize the molecular interactions involving the AAs and the IL at different concentrations and temperatures. Transfer limiting apparent molar volume, V φ 0 tr , has been calculated to determine the solute−solvent interaction in an aqueous medium. The thermodynamic parameters such as Δμ 1 0⧧ , Δμ 2 0⧧ , ΔS 2 0⧧, and ΔH 2 0⧧ also suggest that the intermolecular interaction in the ground state is more significant compared to that in the transition state of two ternary systems. The UV−vis and 1 H nuclear magnetic resonance spectroscopy data also supported our experimental and theoretical observations. Optimization energy calculation obtained from the computational technique leads to the consequence of stability of the ternary system (IL + AA + H 2 O) at the molecular level.

Dielectric permittivity and relaxation dynamics of binary and ternary mixture of stearic acid on various concentration and their thermodynamic effects are studied. The static dielectric constant (" 0 ), dielectric permittivity (" 0 ) and dielectric loss (" 00 ) are found by bilinear calibration. The relaxation time (), dielectric strength (Á") and the excess permittivity (" E ) are found. The thermodynamic parameters such as enthalpy (ÁH), entropy (ÁS) and Gibb's free energy (ÁG) are evolved. The significant changes in dielectric parameters are due to the intramolecular and intermolecular interactions in response to the applied frequency. The permittivity spectra of stearic acid-alcohol in the frequency range of 10 MHz to 30 GHz have been measured using picoseconds Time Domain Reflectometry (TDR). The dielectric parameters (" 0 , " 0 , " 00 ) are found by bilinear calibration method. Influence of temperature in intermolecular interaction and the relaxation process are also studied. The FT-IR spectral analysis reveals that the conformation of functional groups and formation for hydrogen bonding are present in both binary and ternary mixtures of stearic acid.

“…For this reason, it is very important to investigate the dissolution and solvation processes of amino acids in various media. Such studies are carried out in water, various organic solvents, and water–organic mixed solvents. − This work is a continuation of previous thermochemical studies of the dissolution and solvation processes of various amino acids in aqueous–organic mixtures. − As the object of the thermochemical study was selected l -asparagine (I). l -aspsragine is ß-amide of aspartic acid and can be found in animal protein; it is one of the principle and abundant amino acids involved in the transport of nitrogen; and it is very active in converting one amino acid into another (amination and transamination).…”

Some thermodynamic parameters of the dissolution and solvation of L-asparagine in aqueous solutions of amides were obtained using calorimetry and calculation methods. The influence of the physicochemical properties of organic solvents on the energy of interparticle interactions with L-asparagine molecules in aqueous solutions was studied. All of the data obtained were compared with similar data for L-glutamine. The main differences and similarities of the thermodynamic characteristics of the dissolution and solvation of L-asparagine and L-glutamine in aqueous solutions of organic solvents were established. Some recommendations were given when choosing water−organic mixtures for predicting the standard thermodynamic properties of aqueous protein systems.
