A new dipeptide, glycil-L-spinacine, has been synthesised and fully characterised. Protonation constants have been determined and binary Cu(II) complex formation equilibria investigated in an aqueous solution (25 °C, I = 0.1 mol dm-3, KNO3) using the potentiometric and spectrophotometric techniques. Mononuclear and binuclear complex species have been found to form. Binding sites and structure hypotheses are discussed on the basis of available experimental and literature data.

Abstract

A new dipeptide, glycil-L-spinacine, has been synthesised and fully characterised. Protonation constants have been determined and binary Cu(II) complex formation equilibria investigated in an aqueous solution (25 °C, I = 0.1 mol dm-3, KNO3) using the potentiometric and spectrophotometric techniques. Mononuclear and binuclear complex species have been found to form. Binding sites and structure hypotheses are discussed on the basis of available experimental and literature data.
