Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Proteins are found to have two different types of secondary structures viz.

A	Peptide bonds
B	van der Waals forces
C	Hydrogen bonds
D	Dipole-dipole interactions

Explanation:

Detailed explanation-1: -Proteins are found to have two different types of secondary structures: alpha helix and beta pleated sheet.

Detailed explanation-2: -These two folding pattern are particularly common because they result from hydrogen bonds forming between the N-H and C=O groups in the polypeptide backbone. Because amino acids side chains are not involve in forming these hydrogen bonds, helices and sheets can be generated by many different amino acids sequences.

Detailed explanation-3: -Alpha-Helix and Beta-Pleated sheets are types of the secondary structure of the protein. They both are shaped by hydrogen bonding between the carbonyl O of one amino acid and the amino H of another.
