In multi-subunit proteins,such as hemoglobin,the different subunits are usually bound to one another by all of the following EXCEPT
A) hydrogen bonds.
B) electrostatic interactions.
C) hydrophobic interactions.
D) peptide bonds.

Question

Quizplus · Accepted Answer

Peptide bonds join together amino acids within a single protein subunit, but they do not directly bind different subunits to each other. Instead, different subunits are typically held together by noncovalent interactions such as hydrogen bonding, electrostatic interactions, and hydrophobic interactions.
