The acid–base properties of γ-l-glutamyl-l-cysteinyl-glycine (glutathione, GSH) were determined by potentiometry (ISE-H+, glass electrode) in pure NaI(aq) and in NaCl(aq)/MgCl2(aq), and NaCl(aq)/CaCl2(aq) mixtures, at T = 298.15 K and different ionic strengths (up to I c  ~ 5.0 mol L−1). In addition, the activity coefficients of glutathione were also(More)
New potentiometric experiments have been performed in NaCl and in (CH3)4NCl media, to determine the protonation constants, the protonation enthalpy changes and the solubility of six natural α-amino acids, namely Glycine (Gly), Alanine (Ala), Valine (Val), Leucine (Leu), Serine (Ser) and Phenylalanine (Phe). The aim of the work is the rationalization of the(More)
