Abstract

X-Ray absorption near-edge spectroscopy (XANES) has been used to probe the substrate mediated reduction of Cu(2+) in Abeta-Cu(2+) complexes by ascorbate and the neurotoxin 6-hydroxydopamine (6-OHDA), however dopamine and, in particular, cholesterol are incapable of reducing soluble monomeric Abeta-Cu(2+) complexes.
