HUMAN NUTRITION

Detailed explanation-1: -It is formed from the breakdown of a larger protein, called amyloid precursor protein. One form, beta-amyloid 42, is thought to be especially toxic.

Detailed explanation-2: -Plaques form when protein pieces called beta-amyloid (BAY-tuh AM-uh-loyd) clump together. Beta-amyloid comes from a larger protein found in the fatty membrane surrounding nerve cells. Beta-amyloid is chemically “sticky” and gradually builds up into plaques.

Detailed explanation-3: -The amyloid-beta precursor protein is an important example. It is a large membrane protein that normally plays an essential role in neural growth and repair. However, later in life, a corrupted form can destroy nerve cells, leading to the loss of thought and memory in Alzheimer’s disease.

Detailed explanation-4: -Abstract. Amyloid beta peptide (A) is produced through the proteolytic processing of a transmembrane protein, amyloid precursor protein (APP), by -and -secretases.
