Resumo
Thermal effects of the interaction between a glycyl-tyrosine solution and solutions of HNO3 and KOH in different pH ranges at a temperature of 298.15 K and ionic strengths of 0.25, 0.5, and 0.75 (KNO3) are measured via calorimetry. Thermal effects of the stepwise dissociation of the dipeptide are determined. Standard thermodynamic characteristics ΔrH°, ΔrG°, and ΔrS° of acid—base reactions in aqueous solutions of glycyl-tyrosine are calculated. The relationship between the thermodynamic characteristics of dipeptide dissociation and the structure of this compound is examined.
