Stability of α - Helix structure of proteins depends upon

Step-by-step solution

The secondary structure of protein refers to the shape in which a long polypeptide chain can exist. They are found to exist in two different types of structures viz. 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 and - NH - groups of the peptide bond. α -helix Is one of the most common ways in which a polypeptide chain forms all possible hydrogen bonds by twisting into a right handed s
