Scientists demonstrate the influence of nanoparticles and surrounding ions on the formation of beta-sheet structure in amyloid beta proteins. Protein function and activity is determined by both their ...

Proteins modulate the majority of all biological functions and are primarily composed of highly organized secondary structural elements such as helices, turns and sheets. Many of these functions are ...

This is a preview. Log in through your library . Abstract A procedure is described to utilize blue dextran-Sepharose as an affinity chromatographic column specific for the super-secondary structure ...

All proteins are made of basic secondary structure units, either α-helix or β-sheets, determined by hydrogen bonding between the amino acids within a peptide chain. On a larger scale, structures are ...
