WebAA amyloidosis is caused by fragments of amyloid A protein, and affects the kidneys in about 80 percent of cases. It can complicate chronic diseases characterized by … Amyloid beta is commonly thought to be intrinsically unstructured, meaning that in solution it does not acquire a unique tertiary fold but rather populates a set of structures. As such, it cannot be crystallized and most structural knowledge on amyloid beta comes from NMR and molecular dynamics. … Meer weergeven Amyloid beta (Aβ or Abeta) denotes peptides of 36–43 amino acids that are the main component of the amyloid plaques found in the brains of people with Alzheimer's disease.
