Question

The helical structure of protein is stabilized by

Answer 1

The stability of helical structure of protein is due to hydrogen bonding between hydrogen of amino group of nth amino acid and oxygen of carbonyl group of n+4th amino acid.

Answer 2

Explanation:

• 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
