The secondary structure of proteins refers to the shape in which a long polypeptide chain can exist. They are found to exist in two different types of structures, i.e. α-helix and β-pleated sheet structure. These structures arise due to the regular folding of the backbone of the polypeptide chain due to hydrogen bonding between - overset underset||OC - and - NH group of the peptide bond.

Q. Which of the following statements is incorrect about the secondary structure of protein?

It refers to the shape in which long polypeptide chain can exist

It exists in two different type of structures, i.e. $α$ -helix and $β$ -pleated sheet structure

Its structure arises due to regular folding of the backbone of the polypeptide chain

There is the covalent bonding between $> C = O$ and $- N H$ groups of the peptide bond
