Question

Is there free rotation around peptide bond?

Answer 1

Explanation:

Possible resonance structures and electron representations, peptide bonds have partial double bond characteristics.

1. It is well known that the rotation around the peptide bond is restricted.
2. The partial double bond nature of peptide bonds is known to affect protein structure.
3. This is because only alpha carbons in the protein backbone can move freely around their binding axes.

Hence, Restricted rotation is around peptide bond.
