In many cases, the impact of the HIV/AIDS epidemic on families, communities, and countries has feedback effects that influence the course of the epidemic –- for example, poverty and the breakdown of social and economic systems impair community systems that could help to stem the spread of infection.
Explanation:
Answer:
a. Amyloid fibrils have a high amount of β-sheet structure.
c. 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.
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.
