Which of the following is true of protein secondary structures?
A) They are the linear sequences of amino acids.
B) They are the repetitive conformations of the protein backbone.
C) They are held together by strong van der Waals forces of attraction.
D) They include parallelly arranged β-pleated sheets only.

Question

Quizplus · Accepted Answer

Protein secondary structures refer to the repetitive conformations of the protein backbone, such as α-helices and β-pleated sheets. They are not the linear sequences of amino acids (A) or held together by strong van der Waals forces of attraction (C). While β-pleated sheets are a common secondary structure, they are not the only type (D).
