Detailed explanation-1: -The secondary structure arises from the hydrogen bonds formed between atoms of the polypeptide backbone. The hydrogen bonds form between the partially negative oxygen atom and the partially positive nitrogen atom.

Detailed explanation-2: -Answer and Explanation: Hydrogen bonds are very important in protein structure because they connect various amino acids together in order to form polypeptides. Through doing so, they stabilize the secondary through quaternary structures of the protein.

Detailed explanation-3: -Hydrogen bonds between polar amine and carboxyl groups alleviate the desolvation penalty of those groups as they become buried in protein’s native structure. This, in turn, gives rise to the familiar protein secondary structures, such as alpha-helices and beta-sheets.

Detailed explanation-4: -Secondary structure refers to regular, recurring arrangements in space of adjacent amino acid residues in a polypeptide chain. It is maintained by hydrogen bonds between amide hydrogens and carbonyl oxygens of the peptide backbone.

Detailed explanation-5: -Hydrogen bonding is the strongest form of secondary bonding and is formed from the polar nature of molecules containing hydrogen. The hydrogen side of the molecule is more positive than the atom it is bonded to, allowing an attraction to form with the negative end of another molecule.
