Which consequence diminishes the stability of the alpha helix structure?

💡 Explanation

Alpha helix stability diminishes if proline is present because its rigid cyclic structure prevents amide hydrogen atoms participating in *hydrogen bonding*, therefore destabilizing the helix, rather than stabilizing it via hydrophobic interactions.
