Detailed explanation-1: -[A] : Peptide bonds are present in primary, secondary & tertiary structures of proteins .
Detailed explanation-2: -R group interactions that contribute to tertiary structure include hydrogen bonding, ionic bonding, dipole-dipole interactions, and London dispersion forces – basically, the whole gamut of non-covalent bonds.
Detailed explanation-3: -The tertiary structure of a protein refers to the overall three-dimensional arrangement of its polypeptide chain in space. It is generally stabilized by outside polar hydrophilic hydrogen and ionic bond interactions, and internal hydrophobic interactions between nonpolar amino acid side chains (Fig.
Detailed explanation-4: -Protein tertiary structure. For example, amide hydrogen atoms can form H‐bonds with nearby carbonyl oxygens; an alpha helix or beta sheet can zip up, prompted by these small local structures. Hydrophobic interactions among the amino acid side chains also determine tertiary structure.
Detailed explanation-5: -So, the correct option is ‘Glycosidic bond’.
