In this communication, we report the compressibility measurements made on amino acids in water at 25ºC, compared with aqueous short-chained amines and carboxylic acids. The effect of the charge caused by protonation of the amino group and/or deprotonation of the carboxylic one was tested. The concept of additivity of the hydration number with the constituents of solute molecule was applied and discussed.
