Amyloid β Peptides

More Information »Amyloid β (Aβ) peptides are the major component of amyloid plaques found in the brains of Alzheimer's patients. Aβ is formed from the progressive cleavage of amyloid precursor protein (APP) by β- and γ-secretase. Two Aβ peptides are formed from APP degradation.
