Question

In Alzheimer disease the aggregation of this happens.

• A. Phospholipids
• B. Haemoglobin
• C. Amyloid $\beta$-peptide
• D. Nucleic acid

Answer 1

The correct option is C Amyloid $\beta$-peptide

• Amyloid beta peptides of 36–43 amino acids that are crucially involved in Alzheimer's disease as the main component of the amyloid plaques found in the brains of Alzheimer patients.
• The peptides derived from the amyloid precursor protein (APP), which is cleaved by beta secretase and gamma secretase to yield Aβ peptides. Hence, In Alzheimer disease, the aggregation of this happens due to Amyloid β-peptide.
So, the correct answer is 'amyloid β-peptide'.
