A modified latimer diagram that displays a summary of the redox chemistry for N-truncated Aβ peptides. This is based on the XAS-EC studies. The equilibrium arrows indicate the main component of the equilibrium. CuII from the ATCUN site ([{\rm Cu}^{\rm II}_{\rm ATCUN}]:Aβ4–16) to the bis-His site ([{\rm Cu}^{\rm I}_{{\rm H}_{13/14}}]:Aβ4–16) could reasonably transfer via the H6H13/14 intermediate site (IS). Here, E is the redox potential and K is the equilibrium constant of the redox reaction.
