Question
α – helix is stabilised by ans. Disulphide bonds
Hydrogen bonds
Ionic bonds
Vander Wall’s forces
Solution
The α-helix structure in proteins is stabilized by Hydrogen bonds. These bonds occur between the oxygen of the carbonyl group in one amino acid and the hydrogen in the amino group of the fourth amino acid down the chain. This pattern of bonding pulls the chain into a helical structure. The other options, Disulphide bonds, Ionic bonds, and Vander Wall’s forces, also play roles in protein structure, but they are not the main stabilizing force in an α-helix.
