The interplay between solute solvation and solute- solute interactions in solutions containing
amino acids, peptides and related Page 1 Pure & Appl. Chem., Vol. 65, No. pp. 2551-2560, 1993 …

The protonation equilibria for 20 standard α-amino acids in solutions have been studied pH-
potentiometrically. The dissociation constants (pKa) of 20 amino acids and the …

Proton− ligand and metal− ligand stability constants formed in the ternary system NiII+
adenosine-5 '-triphosphate (ATP)+ asparagine are determined pH-metrically in different …

The apparent molar volumes V 2, φ, apparent molar isentropic compressibilities KS, 2, φ,
