Molecular Interaction Dynamics of L-Arginine in 2% aqueous D- Fructose: A Comprehensive Insight of Volumetric, Acoustic and Viscometric properties

Present study investigates the interaction of L-Arginine in an aqueous D-fructose medium through ultrasonic velocity(U), density(ρ) and viscosity(ⴄ) measurements for the range of 293.15K to 313.15 K. Results obtained through experimental data is used to analyze some thermos-acoustic, volumetric and viscometrical parameters such as free length, Gibb’s free energy, molar volume, Rao’s constant, compressibility, Wada’s constant and relaxation time of ternary mixture of L-Arginine and 2% D-Fructose in the concentration range of 0.01M to 0.1 M. Due to the unique structure of L-Arginine it allows to get involved in various chemical reactions. There are significant intermolecular and intra-molecular interactions in presence of co-solute, D-Fructose. The study throws light on ion-ion interactions in the complex behavior of L-Arginine and also the effect on heat-denaturation temperature of protein due to aqueous fructose in a ternary mixture.
