Detailed explanation-1: -Tertiary structure is stabilized by multiple interactions, specifically side chain functional groups which involve hydrogen bonds, salt bridges, covalent disulfide bonds, and hydrophobic interactions.
Detailed explanation-2: -Furthermore, hydrogen bonds and ionic interactions between the polar, charged amino acids contribute to the tertiary structure. These are all weak interactions in the cellular environment, but their cumulative effect helps give proteins their unique shape.
Detailed explanation-3: -As with disulfide bridges, these hydrogen bonds can bring together two parts of a chain that are some distance away in terms of sequence. Salt bridges, ionic inter-actions between positively and negatively charged sites on amino acid side chains, also help to stabilize the tertiary structure of a protein.
Detailed explanation-4: -Hydrogen bonding in the tertiary structure of a protein occurs between the −NH3+ − N H 3 + group of a side chain of one amino acid and the −COO− − C O O − group of a side chain of another amino acid.
