Web29 nov. 2024 · This is known as protein denaturation. The type of bonds involved in the formation of the tertiary protein structure include hydrogen bonds, electrostatic or ionic bonds, covalent bonds or hydrophobic bonds. Hydrostatic bonds – form between the hydroxyl (OH) group and an adjacent hydrogen molecule, providing a strong bond … WebIonic bonds form when one atom has a much higher electronegativity than another. This causes the electronegative atom to pull electrons from the less electronegative atom, forming ions that stick to one another via electrostatic forces. Hydrogen doesn't form ionic bonds because it has a very average electronegativity of 2.1.
