The one that does not stabilize 2 ∘ and 3 ∘ structures of proteins is

Step-by-step solution

Secondary structure of protein refers to local folded structures that form within a polypeptide due to interactions between atoms of the backbone. They are found to exist in two different types of structures α   –   helix and β   – pleated sheet structures. This structure arises due to the regular folding of the backbone of the polypeptide chain due to hydrogen bonding between - CO group and - NH groups of the peptide bond. Tertiary Structure of Protein arises from further foldi
