amyloid-beta,
Amyloid beta (Aβ, Abeta or beta-amyloid) denotes peptides of 36–43 amino acids that are the main component of the amyloid plaques found in the brains of people with Alzheimer's disease. [2] The peptides derive from the amyloid-beta precursor protein (APP), which is cleaved by beta secretase and gamma secretase to yield Aβ in a cholesterol .
The amyloid-beta peptide appears to play a central role in the pathology of Alzheimer disease. Sporadic Alzheimer disease is the most common cause of dementia, with an estimated 50% to 56% cases in autopsy and clinical series. The disease starts insidiously, with age being the principal risk factor. Amyloid beta peptide (Aβ) is produced through the proteolytic processing of a transmembrane protein, amyloid precursor protein (APP), by β- and γ-secretases. Breakthroughs in molecular medicine have positioned the amyloid-β (Aβ) pathway at the center of Alzheimer’s disease (AD) pathophysiology.Amyloid beta: structure, biology and structure Alzheimer’s is characterized by the buildup of a protein called beta-amyloid, which forms sticky plaques on the brain and can cause brain cells to die. Testing for the presence of these amyloid plaques on the brain is an important part of Alzheimer’s diagnosis and research.

In AD, the dysregulation of the amyloid-beta (Aβ) level leads to the appearance of senile plaques which contain Aβ depositions.amyloid-beta Amyloid beta: structure, biology and structureAlzheimer's disease (AD) is the most prevalent form of dementia which affects people older than 60 years of age.
