Question

Which forces are responsible for the stability of alpha helix

Answer 1

Hey!
here is ur answer....

Hydrogen bonding is responsible for the stability of alpha-helical structure of proteins. The C=O group of an amino acid in the alpha helix formshydrogen bond with the N-H bond of amino acid four residues later.

Answer 2

Answer:

The α helix is stabilized by hydrogen bonds between the NH and CO groups of the main chain. In particular, the CO group of each amino acid forms a hydrogen bond with the NH group of the amino acid that is situated four residues ahead in the sequence
