Out of the following, which type of interaction is responsible for the stabilisation of α−\alpha -helix structure of proteins?

Options

  1. ACovalent bonding
  2. BIonic bonding
  3. CHydrogen bonding
  4. Dvander Waals forces

Correct answer

C. Hydrogen bonding

Step-by-step solution

Hydrogen bonding is responsible for the stacking of α−\alpha -helix structure of protein.

The α\alpha-helix structure of proteins is stabilized by intramolecular H-bonding between C−O of one amino acid residue and the N−H of the fourth amino acid residue in the chain.
