Abstract
Heat effects of stepwise dissociation of D,L-valyl-D,L-leucine, L-leucyl-L-leucine, D,L-leucylglycine, and glycyl-D,L-leucine (298.15 K; 0.1, 0.5, or 1.0 mol/L KNO3) have been determined by direct calorimetry. Standard thermodynamic parameters of the studied equilibria have been calculated.
