Any one of various complex proteins that are deposited in tissues in different disease processes. In neuropsychiatry, the proteins of particular interest are beta-amyloid (also known as amyloid beta [A-beta]; the major constituent of the characteristic senile plaques of alzheimer’s disease) and the amyloid precursor protein (app).
A waxy, starch-like protein that tends to build up in tissues and organs in certain pathologic conditions.

Waxy protein that forms in some tissues during the development of various diseases, e.g. forming disc-shaped plaques in the brain in Alzheimer’s disease.
A glycoprotein, resembling starch, that is deposited in the internal organs in amyloidosis.
Resembling starch; starchlike.
In the intricate realm of the brain, there exists a peculiar substance characterized by its translucent and waxy nature. Comprised primarily of proteins, this substance manifests as plaques, which are abnormal deposits found within the brain.
