How do tje following interactions help to stabilize the tertiary and quaternary structure of a protein? Give an example of a pair of amino acids that could give rise to each interaction.

A) Side-chain hydrogen bonding. check all that apply

B) Disulfide bonds. check all that apply.

Threonine and glutamine can form hydrogen bonds Two cysteine residues can form hydrogen bonds O Side chains connect distant parts of a polypeptide chain and introduce loops into the chain Side chains that can form hydrogen bonds are located on the outside of a protein, where they can stabilize tertiary structure by forming hydrogen bonds with water Hydrogen bonds stabilize quaternary protein structure by holding together several protein strands. Hydrogen bonds stabilize quaternary protein structure by holding together several protein strands Threonine and glutamine form disulfide bridges.
