The alpha-helix of a protein is maintained by specific interactions between the backbone atoms. Identify the force responsible for this secondary structure.
Q1. The alpha-helix of a protein is maintained by specific interactions between the backbone atoms. Identify the force responsible for this secondary structure.
Answer: Hydrogen bonds
Explanation: Secondary protein structures like alpha-helices are stabilized by hydrogen bonding between N-H and C=O groups. Peptide bonds are tempting but form primary structures.
