Which forces are responsible for the stability of α-helix? Why is it named as 3.6 helix?
The stability of alpha –helix structure is due to intramolecular of H-bonding between –NH- and –CO- groups of the same polypeptide chain. The alpha-helix is termed as 3.613 helix as each turn of the helix has nearly 3.6 amino acids and the hydrogen bonding leads to the formation of a 13-membered ring.
