beta-amyloid protein

be·ta-am·y·loid protein

 (bā′tə-ăm′ə-loid′, bē′-)
An amyloid that circulates in human blood and in cerebrospinal fluid and is deposited into plaques found in the brains of patients with Alzheimer's disease. Also called amyloid beta-protein.

[From the beta sheets characterizing its structure.]

Researcher Abha Chauhan, PhD, and associates say an extract in the nuts may provide a protective effect against oxidative damage caused by beta-amyloid protein. A build-up of this protein leads to beta-amyloid plaque, which is believed to play a major role in the development of the disease.
