I am on the last of 3 chances to get this question correct. So far 1 and 3 together are incorrect, and 2 and 4 together are incorrect.

Which of the following bonds or interactions is/are possible contributors to the stability of the tertiary structure of a globular protein?

Answer options:

1. peptide bonds between a metal ion cofactor and a histidine residue

2. hydrophobic interactions between histidine and tryptophan R groups

3. covalent disulfide cross-links between two methionine residues

4. hydrogen bonds between serine residues and the aqueous surroundings

Explanation / Answer

The tertiary structure of a protein is define as the 3-D structure formed by the polypeptide chain due to the numerous interactions that the sequence can have with itself and its environment including hydrophobic interactions and H-bonding.
