By mixing a small peptide with equal amounts of its mirror image, scientists have created an unusual protein structure known as a 'rippled beta sheet' and obtained images of it using x-ray ...

The mirror-image peptides joined in pairs to form "dimers" with the predicted structure, but they did not form the extended, periodic rippled beta-sheet layer topography hypothesized by Pauling ...

The research team at Washington University have revealed a new way to investigate these aggregates. Leveraging novel microscopy techniques, researchers were actually able to measure amyloid fibril ...
