The alpha-helix structure is stabilized by:
A)covalent bonds between adjacent functional groups.
B)hydrogen bonds along the peptide backbone.
C)association with helicase stabilizing enzymes.
D)noncovalent interactions with water.
E)cationic elements found in water solutions.

Question

Quizplus · Accepted Answer

The alpha-helix structure is stabilized by hydrogen bonds between the carbonyl oxygen of one amino acid and the amide hydrogen of the amino acid four residues down the peptide chain. These hydrogen bonds help to maintain the helical shape of the protein.
