β-Amyloid (1-16) is an amyloidogenic protein fragment with a sequence derived from β-amyloid. It exhibits the ability to bind to metal ions, indicating its involvement in metal-binding processes. β-Amyloid, a peptide, is responsible for the formation of amyloid plaques in the brains of individuals affected by Alzheimer's disease (AD).
β-Amyloid (12-20) is a peptide fragment of β-Amyloid containing the amino acid residues VFF at positions (18-20), suggesting amnestic effects for this triad.
