Figure 10
Suggested mechanism for the photoreduction of Cu insulin. The redox reaction occurs as a pre-equilibrium between the type II copper insulin species, which is followed by an irreversible step in which the water structure of the reduced copper deteriorates (indicated by a grey cloud of water) and then stabilizes. For simplicity, the different species are renamed A, B and C.
