a-helix is a secondary structure of proteins formed by twisting of| polypeptide chain into a right-handed screw-like structure. Which type of interactions is responsible for making the o-helix structure stable?

 
a-helix is a secondary structure of proteins formed by twisting of the polypeptide chain to a right-handed screw-like structure. Hydrogen bonds formed between-NH-group of amino acids in one turn with the >C=0 groups of amino acids belonging to adjacent turn is responsible for making theα-helix structure stable.
