Proteins are found to have two different types of secondary structures viz α− helix and β−pleated sheet structure. α−helix structure of protein is stabilized by
A
Peptide bonds
B
Van der Waals forces
C
Hydrogen bonds
D
Dipole – dipole interactions.
Answer
Hydrogen bonds
Explanation
Solution
α−Helix structure of protein is stabilized by hydrogen bonds between – NH- group of one amino acid residue and the 
group of another amino acid residue.
