Quaternary structure refers to the highest level of protein organization. It involves the assembly of multiple polypeptide chains, known as subunits, that come together to form a functional protein complex. Each subunit in a quaternary structure can be identical or different, and the interactions between these subunits are crucial for the protein's overall functionality. The interactions that stabilize quaternary structures include hydrogen bonds, ionic bonds, hydrophobic interactions, and disulfide bridges.
