Secondary structure is associated with which of the following?
A) the sequence of amino acids
B) hydrogen bonding within the backbone
C) hydrogen bonding between the side chains
D) the interaction of protein subunits

Question

Quizplus · Accepted Answer

Secondary structure refers to the local folding patterns of a protein's backbone, and is stabilized by hydrogen bonding between amino acids. Specifically, alpha helices and beta sheets are both examples of secondary structure that are formed by hydrogen bonding between backbone atoms. Choices A, C, and D are all related to other aspects of protein structure and function, but are not directly associated with secondary structure.
