33. Which of the following description is (are) CORRECT regarding protein structure and function?
(A) Secondary structures are the core elements of protein architecture, including o helix, B sheet, and B turn.
(B) Protein tertiary structure are resulted from hydrophobic interactions, hydrogen bonds and ionic
interactions.
(C) Folding of proteins in vivo is promoted by chaperones, which utilize ATP hydrolysis to assist protein
folding.
(D) Abnormally folded proteins can form amyloids and lead to human diseases, such as Alzheimer's disease
and Parkinson's disease.
(E) The structure and function of a protein is only determined by its amino acid sequence.
