What Is True About the Rotation About Bonds in a Protein

question 6

Multiple Choice

What is true about the rotation about bonds in a protein backbone?

• A)The rotation is free about all bonds in the backbone,except for the bond between the nitrogen and the alpha carbon in proline residues.
• B)The bond between the carbonyl carbon and nitrogen is restricted.Other bonds are free to rotate depending only on steric hindrance or the presence of proline residues.
• C)All bonds in the backbone have restricted rotation and partial double-bond character.
• D)The rotation is free only about the peptide bond.The other bonds are restricted by steric hindrance and the presence of proline residues.
