Which of the following interactions are present in the tertiary structure of a protein?Group of answer choicesHydrogen bondsAll are present.Disulfide bondsLondon dispersion forces PreviousNext
Solution
The tertiary structure of a protein is determined by a variety of interactions, including:
-
Hydrogen bonds: These are weak bonds that occur when a hydrogen atom in one molecule is attracted to an electronegative atom (usually nitrogen or oxygen) in the same or different molecule.
-
Disulfide bonds: These are covalent bonds that form between two cysteine residues in a protein. They are much stronger than hydrogen bonds and play a crucial role in stabilizing the protein's structure.
-
London dispersion forces: These are weak intermolecular forces that arise from the interactions of instantaneous multipoles in molecules. They are present in all atoms and molecules and contribute to the overall stability of the protein.
So, the answer is "All are present."
