Molecular model of human brain-derived beta-amyloid fibrils isolated from a patient with Alzheimer's disease. The fibrils are made up of beta-amyloid peptides. These insoluble fibres resist degradation and so build-up in brain tissue, forming the amyloid plaques found in the brains of Alzheimer's disease patients.
