RELATIONSHIP BETWEEN MOLAR PARAMETERS OF VISCOUS FLOW AND ULTRASONIC WAVE PROPAGATION IN AQUEOUS SOLUTIONS OF AMINO ACIDS

Quantitative structure-property relationship (QSPR) correlations have been widely applied in biological active solutes over several decades. Many new descriptors (parameters) have been developed. Of the many parameters reported in literature, it is argued that the vol-ume (constitutional, geometrical, compressibility) properties play an important role in deter-mining the overall state of proteins consisting of the various amino acids residuals. On basis of experimental data on density, viscosity and ultrasound velocity for aqueous solutions of amino acids, the volume effects in characteristics of impulse transfer and ultrasound wave were studied. The analysis on the correlations between molar parameters of viscosity and ul-trasound velocity and molar volume for aqueous solutions of glycine, alanine, aminobutanoic acid, valine, leucine and serine has been carried.
