Abstract

Molecular interactions of Tryptophan (an essential amino acid) in the presence of essential metal ions like Zn²⁺ and Co²⁺ at 303.15K have been studied by using ultrasonic interferometer supplied by M/s Mittal Enterprises, New Delhi, operating at a frequency of 2 MHz. and a bicapillary pyknometer to measure the density of solution. The data is processed to obtain the various acoustic and thermodynamic parameters to study the molecular interactions in aqueous solutions. The values of apparent molar volume, apparent molar compressibility, partial molar volume, partial molar compressibility, specific acoustic impedance, relative association, intermolecular free length have been calculated by using standard mathematical relations. The concentration dependences of the density and ultrasonic velocity were tried to fit into linear and polynomial equations. It is interesting to see the associative interaction among the molecules and ions as well as the increase in the stacking interactions between the metal ions and tryptophan.
