Resumo
Protolytic equilibria in aqueous solutions of glycyl-DL-serine, glycyl-DL-threonine, and glycyl-DL-valine are investigated by means of potentiometry and calorimetry. Dissociation constants and heat effects of the above dipeptides are determined. Standard thermodynamic characteristics (pK°, ΔdisG°, ΔdisH°, ΔdisS°) of the investigated equilibria are calculated. The obtained results are compared to corresponding data on relative compounds.
