Does Tertiary Structure Have Hydrogen Bonds?

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.

What bonds are involved in tertiary structure?

There are four types of tertiary interactions: hydrophobic interactions, hydrogen bonds, salt bridges, and sulfur-sulfur covalent bonds.

Why are hydrogen bonds important in tertiary structure?

Hydrogen bonds form between the oxygen of each C=O. bond in the strand and the hydrogen of each N-H group four amino acids below it in the helix. The hydrogen bonds make this structure especially stable. The side-chain substituents of the amino acids fit in beside the N-H groups.
