Interactions that Maintain Tertiary Structure. Most polar amino acid side chains are on the outside surface so they can hydrogen bond to water to solubilize the protein. Salt Bridges: Protein fold so that positively charged side chains are often located adjacent to negatively charged side chains. The salt bridge or ionic bond between the charged functional groups helps stabilize the tertiary structure.
