Detailed explanation-1: -The main forces which stabilize the secondary and tertiary structures of proteins are hydrogen bonds, disulphide linkages, van der Waals and electrostatic forces of attraction.
Detailed explanation-2: -Four interactions stabilize the tertiary structure of a protein: (a) ionic bonding, (b) hydrogen bonding, (c) disulfide linkages, and (d) dispersion forces.
Detailed explanation-3: -Secondary structure elements that are formed early in protein folding (15, 16) are stabilized by both sequence-dependent side-chain interactions and sequence-independent backbone interactions (particularly hydrogen bonding).
Detailed explanation-4: -Answer and Explanation: Covalent bonds, hydrogen bonds, and hydrophobic interactions are the forces that stabilize the tertiary structure of a protein.
