Popis:	The heat effects of the interaction between a solution of DL-α-alanyl-DL-norleucine and solutions of HNO3 at different pH values at 288.15 and 308.15 K and ionic strength values of 0.5, 1.0, and 1.5 (background electrolyte, KNO3) are measured via calorimetry. The heat effects of the stepwise dissociation of the dipeptide are determined. Standard thermodynamic characteristics (ΔrH°, ΔrG°, ΔrS°, and $$\Delta C_{p}^{^\circ }$$ ) of the reactions of acid–base interaction in aqueous solutions of DL-α-alanyl-DL-norleucine are calculated. The relation between the thermodynamic characteristics of the dissociation of a dipeptide with the structure of this compound is considered.
