The osmotic coefficients of aqueous solutions of the alpha, omega-amino acids: 3-aminopropanoic acid, 4-aminobutanoic acid, 5-aminopentanoic acid and 6-aminohexanoic acid were measured using the isopiestic method at 298.15 K. The activity coefficients of these solutes were calculated from the experimental osmotic coefficients and the pairwise free energy coefficients for solute-solute interactions were obtained using the McMillan-Mayer theory. The results are compared with the activity coefficients of alpha-amino acids and are discussed in terms of solute-solute interactions.
