摘要：
Protolytic equilibria in L-glutamine aqueous solutions were studied calorimetrically. The measurements were carried out at 298.15, 308.15, and 318.15 K and ionic strengths of 0.5, 1.0, and 1.5 (potassium nitrate). The thermodynamic parameters (pK, Delta G, Delta H, Delta S) of stepwise dissociation of L-glutamine both in water-salt solutions and in the standard solution were obtained.
