Which forces are responsible for the stability of α‐helix? Why is it named as 3.613 helix?

Answer»

Hydorgen bonds between –N‐H and —C=O groups of peptide bonds give stability to the structure.

It is known as 3.6₁₃ helix, since each turn of helix has approximately 3.6 amino acid residue and a 13 member ring is formed by hydrogen bonding.
