Question

What are the common types of secondary structure of proteins?

Answer 1

Secondary structure is formally defined by the pattern of hydrogen bonds between the aminohydrogen and carboxyl oxygen atoms in the peptide backbone. 

Answer 2

There is two common type of secondary structure of the proteins that will be alpha – helix structure whereas another one will be Beta pleated sheet structure.

In the helix structure, there is an amino acid group – NH that will form the H-bond with the C=O.

In the pleated structure, it will have the stretched out chains of the peptide with maximum extension.
