Question

Differentiate between primary and secondary structure of a protein.

Answer 1

Primary Structure	Secondary Structure
Proteins may have one or more polypeptide chains. Each polypeptide in a protein has amino acids linked with each other in a specific sequence and this sequence of amino acids is said to be the primary structure of that protein.	The secondary structure of a protein refers to the shape in which a long polypeptide chain can exit. These structures arise due to the regular folding to the backbone of the polypeptide chain due to H-bonding between -COOH and -NH- groups of the peptide bond.
