In Alzheimer’s disease, amyloid plaques are primarily formed by:
Amyloid-β peptide is the scientifically accurate answer to this question. Within the study of Protein Folding, this concept is well-established through extensive research and is documented in standard scientific literature. The specific properties, mechanisms, or characteristics of Amyloid-β peptide directly address what is being asked. Among the other options, Tau protein, α-Synuclein, and PrPSc do not correctly answer this question because they either refer to different concepts, describe properties of other molecules or processes, or represent common misconceptions about this topic.
