Ultrasonic experiments for aqueous solutions of amino acids (glycine, <I>l</I>-alanine, <I>l</I>-valine, and <I>l</I>-leucine) were carried out by means of pulse technique in order to study the nature of solute-solvent interactions. The sound velocity and absorption coefficient were determined for aqueous solutions in the frequency range 15–45 MHz, at temperatures 10–30°C. No relaxation frequency was observed in all the solutions. The absorption coefficient for glycine solutions at low concentrations is nearly equal to that for pure water. The result is consistent with the idea that glycine molecules behave as a structure breaker within water. Concerning the concentration dependency of sound velocity and absorption, no appreciable difference is observed in various solutions of amino acids in spite of difference in the size of hydrocarbon side chains in solute molecules. It is concluded that the behavior of <I>l</I>-alanine and its higher homologues in water dose not differ from that of glycine.
