Answer:
Options 1, 3 and 4.
Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease.
An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.
4) Soluble proteins that misfold and form amyloid fibrils become insoluble.
Explanation:
Amloid fibrils are peptide or proteins that are formed during invivo or invitro conditions. They ate formed when soluble proteins combine together to for insoluble fibres that are resistant to degradation. They are found in extracellular tissues and posses pathological effect. They accumulate after nerve cells and causes several illness.
