e. Proteins that form amyloid fibrils are normally soluble.

Explanation:

Amyloids can be defined as fibrillar protein aggregates composed of a β-sheet secondary structure. In general, the amyloid fibrils are composed by soluble proteins that are assembled to form insoluble resistant to degradation fibers. In humans, defective amyloid proteins produced by misfolding are known to produce diseases (amyloidosis) capable of altering the function of tissues and organs. Systemic forms of amyloidosis are common in neurodegenerative disorders.
