(a) EPR spectra of a frozen solution (77 K) of PAla-Cu(II) at different reaction times. [Cu(II)]=1.0×10⁻³ M, 𝑅=[PAla]/[Cu(II)]=4, pH=8.7. (b) The variation of the intensity of Cu(II) signal, as (%) of the initial signal (𝑡=0 min), during the reaction time for the systems Pala-Cu(II) and PGlygly-Cu.
