A) Disulfide bridges.
B) Hydrophobic bonds.
C) Amide linkages between amino acid sidechains.
D) Ester linkages between sidechains of acidic and alcoholic amino acids.
E) Hydrogen bonds to water molecules.

Question

Quizplus · Accepted Answer

Hydrophobic bonds are a major type of physical/chemical interaction found in the interior of most globular proteins. These interactions occur between nonpolar amino acid sidechains, as these hydrophobic groups tend to cluster together away from the surrounding aqueous environment. This is a major factor in the overall folding and stability of the protein structure.
