Detailed explanation-1: -It is primarily defined by hydrogen bonds between amino acids and carboxyl oxygen atoms. Alpha-Helix and Beta-Pleated sheets are types of the secondary structure of the protein.

Detailed explanation-2: -Secondary structure The most common types of secondary structures are the helix and the pleated sheet. Both structures are held in shape by hydrogen bonds, which form between the carbonyl O of one amino acid and the amino H of another.

Detailed explanation-3: -The other common secondary structure is the beta-pleated sheet. In this structure, two different regions of a polypeptide chain lie side by side and are bound by hydrogen bonds. They make up the core of many globular proteins.

Detailed explanation-4: -An -helix secondary structure is stabilized by hydrogen bonds between carbonyl oxygen and the amino group of every third residue in the helical turn with each helical turn consisting of 3.6 amino acid residues (Fig. 10.1A). The side chain of amino acids is projected outward from the outer helical surface.

Detailed explanation-5: -Protein structures are also classified by their secondary structure. Secondary structure refers to regular, local structure of the protein backbone, stabilised by intramolecular and sometimes intermolecular hydrogen bonding of amide groups.
