 (bā′tə-ăm′ə-loid′, bē′-)
A protein fragment formed by the cleavage of amyloid precursor protein that aggregates into deposits characteristically found in the brains of people with Alzheimer's disease. Also called amyloid beta-peptide, amyloid beta-protein, beta-amyloid peptide, beta-amyloid protein.

[From the beta sheets characterizing its structure.]

The research focuses on the detection of beta-amyloid, a protein which folds incorrectly and forms clumps in the brains of those with Alzheimer's; one of the hallmarks of the disease.
In two other studies, the level of beta-amyloid detected in the eye was significantly correlated with the burden of beta-amyloid in the brain and allowed researchers to accurately identify the people with Alzheimer's in the studies.
