Acetly-β Amyloid (15-20), Amide is a peptides fragment. Acetly-β Amyloid (15-20), Amide inhibits the β-sheet formation and stabilizes structure of Aβ (1–40) peptide. Acetly-β Amyloid (15-20), Amide can be used in study Alzheimer’s disease[1].

Amyloid plaques characteristic of the Alzheimer brain contain fibrils composed of amyloid beta aggregates. Short peptides containing the sequence KLVFF have been shown to bind specifically to the homologous region in Aβ and are used to prevent full length amyloid fibril formation.
