The protonation equilibria of selected glycine dipeptides in ethanol–water mixture: solvent composition effect

Abstract

Knowledge of the protonation constants of small dipeptide is important, interesting and necessary for complete understanding of the physiochemical behavior of dipeptide. In this study, the protonation constants of some aliphatic dipeptides (Gly–Gly, Gly–Val, Gly–Leu, Gly–Thr, Gly–Phe and Gly–Met) were studied in water and ethanol–water mixtures [20% ethanol… (More)
