Effect of Solvent Composition on Protonation Constants of Some Glycine Dipeptides
Stoichiometric protonation constants (log 10 K 1 and log 10 K 2 ) of some aliphatic dipeptides (Gly–Tyr, Gly–Phe, Gly–Val, Gly–Leu, Gly–Thr, Gly–Met and Gly–Pro) were determined potentiometrically in 20, 40, and 60 % (v/v) 1,4-dioxane–water and dimethyl sulfoxide–water mixtures at 25.0 (±0.1) °C wit...
