The Alzheimer's Abeta40 peptide forms soluble oligomers that are extremely potent neurotoxins and strongly impede synapses function. In this study the formation and structure of the large, soluble, neurotoxic Abeta40 oligomer called "beta-ball" were characterized by two-dimensional NMR, circular dichroism
