The degradation of neurotransmitters is a hallmark feature of Alzheimer's disease (AD). Copper bound Aβ peptides, invoked to be involved in the pathology of AD, are found to catalyze the oxidation of serotonin (5-HT) by H<sub>2</sub>O<sub>2</sub>. A combination of EPR and resonance Raman spectroscopy reveals the formation of a Cu(ii)-OOH species and a dimeric, EPR silent, Cu<sub>2</sub>O<sub>2</sub> bis-μ-oxo species under the reaction conditions. The Cu(ii)-OOH species, which can be selectively ...[more]
