“…The partial molar volume Ø V 0 was obtained by a regression analysis based on the least squares method through the following equation: 16 In eq 2, S V is the experimental slope, which shows the strength of solute−solute interactions and is influenced by a number of factors. 11 The computed results of apparent molar volume Ø V , partial molar volume Ø V 0 , and experimental slope S V for the investigated mixture (galactitol in aqueous L-arginine) at various temperatures are reported in Table 4.…”

“…Using measured data, acoustic and volumetric parameters such as isentropic compressibility, specific molar volume, partial molar volume, expansibility, intermolecular free length, and transfer volume of galactitol from water to arginine solutions were computed. These parameters have been used to deliberate molecular interactions occurring in solutions and the structure-making/breaking tendency of the components in working solutions . The objective of the present work is to lift the primary knowledge related to amino acid–sugar alcohol interactions in aqueous solutions, which is still oblivious.…”

In conjunction with the development of people's living standards, the modern world demands good-quality food such as sweets, candies, chocolates, diet drinks, beverages, and so on, but because of obesity and other health issues people concentrate more on sugar-free or low-calorie products. Polyols are such a kind of food with desirable qualities, and they play a role in controlling the blood glucose level in diabetic patients. The density (ρ) and sound speed (u) of sugar alcohol in water and in (0.02, 0.04, and 0.06) mol kg −1 L-arginine solutions at different temperatures (293.15−318.15 K) and atmospheric pressure were measured by using Anton Paar DSA5000M. Experimental density and sound velocity data were further used to compute volumetric and acoustic parameters such as apparent molar volume (Ø V ), partial molar volume (Ø V 0 ), compressibility (Ø k 0), expansibility (Ø E 0 ), and so on. The positive trends of apparent molar volume (Ø V ), and partial molar volume Ø V 0 ), values indicate strong hydrophilic interactions in ternary solutions. These interactions give a complete picture about solvation behavior, the effect of temperature, and hydrogen bonding present among (galactitol + L-arginine) mixtures. The apparent specific volume values were calculated, and it was found that these values of the investigated mixtures lie on the borderline with the reported values of sweeteners. This study may offer a new vision in elucidation of mechanistic modifications between sugar alcohol, amino acid, and their mode of interactions.

In this experimental study, we studied the molecular interactions of L-valine and L-leucine in separate aqueous solutions of D-mannitol at various temperatures and concentrations. The derived parameters, such as apparent molar volume (ϕ v ), limiting apparent molar volume (ϕ v 0 ), viscosity B-coefficient, and Gibbs free energies of activation per mole of solvent and solute, conductance, have been used to predict solute−solvent and solute−solute interactions based on the transition state theory and cosphere overlap model. By adjusting the concentration of L-valine and Lleucine, fluorescence spectra were measured, and the association constant was computed. Hydrophobic−hydrophobic interactions were seen in the 1 H NMR experiments, and these findings were supported by computational research. The primary goal of this research is to comprehend how biologically important D-mannitol interacts with significant amino acids in aqueous solutions, which could be suitable for the pharmaceutical sector. These results are anticipated to offer important foundational knowledge for comprehending how sugar alcohol affects protein conformational stability.
