Abstract

Quantum-chemical calculations of the structure of the molecular forms of glycine and glycylglycine and conjugate ionic forms have been performed. Our own and published data on the thermodynamic characteristics of the reactions of acid–base interactions of glycine and glycylglycine in aqueous organic solutions are summarized, and the influence of the composition of mixed solvents on the acid dissociation constant of the amide group in the copper(II) peptide complex is considered.
