Answer:
The interaction that does NOT maintain tertiary structure is a carbon−carbon bond.
Step-by-step explanation:
The tertiary structure is represented by the superfolding and winding of the secondary structure, constituting very complicated three-dimensional geometric shapes that are maintained by links of: disulfide bond, between the residues of two cysteines; hydrogen bonds, which is formed between the C = O of the carboxylic group and a chain group that has active H; salt bridge, is due to two polar groups of the amino acid chains, which according to the pH will have a positive or negative electrical charge; and hydrophobic interactions, which are interactions between non-polar chains of amino acids within water envelopes.
Carbon-carbon bonds are covalent bonds, which take place between two carbon atoms.
