Amyloid Substance

A fibrous protein complex that consists of Proteins folded into a specific cross beta-pleated sheet structure. This fibrillar structure has been found as an alternative folding pattern for a variety of functional Proteins. Deposits of amyloid in the form of Amyloid Plaques are associated with a variety of degenerative Diseases. The amyloid structure has also been found in a number of functional Proteins that are unrelated to Disease.
