Beta amyloid (1-42) [Aβ(1-42)] is the predominant form of β-amyloid protein found in the brains of patients with Alzheimer′s disease and Down′s syndrome. Beta amyloid (25-35) is the shortest fragment capable for forming beta sheets and maintaining the toxicity associated with the full length amyolid peptides. Acetylation is thought to improve stability in in vitro and in vivo assays.
