Both weak noncovalent interactions and strong covalent bonds stabilize the tertiary structure of the protein (which provides three-dimensional shape).
The major forces stabilizing tertiary structure (which provides three-dimensional shape) are multiple weak noncovalent interactions:- Hydrogen bonds, hydrophobic interactions, ionic bond, and Van der Waals forces.
Covalent (Disulfide) bonds also provide some stability.
