-Helix is a secondary structure of proteins formed by twisting of the polypeptide chain into right-handed screw-like structures. Which type of interactions is responsible for making the -helix structure stable?
When a polypeptide chain is twisted in a right-handed screw fashion to make a stable α-Helix chain, the interaction taking place includes the bonding of each amino acid residues’ -NH group with the in the adjacent turn of the helix.
