In the α helix structure, there is a hydrogen bonding between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain

Explanation:

The common secondary structure of protein are: α helix and β pleated sheet

α helix is a rod like structure. It is a right handed coil of amino acid residue on a polypeptide chain, which may be 4 units or 40 units long. The coil is held together by hydrogen bond between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain. This means that every complete turn of the helix is only 3.6 residues.
