Electrochemical reactions of copper complexes with Aβ(3-16) and pAβ(3-16)

This data set contains cyclic voltammetry redox data from the reaction of copper complexes of the N-truncated β-amyloids Aβ(3-16) and pAβ(3-16) in two different electrolyte solutions and at a wide range of pH.The data obtained in physiological pH (pH ~ 7.4) show that Cu(II) ions in in these peptides undergo reduction Cu(II)/Cu(I) at a potential (Ef)~0.05 V which in other peptides have been shown to enhance production of reactive oxygen species. Detailed voltammetric studies, performed at pH below and above 7.4, revealed the effects of coordination modes on the observed redox processes.
