Disulfide bonds are involved in maintaining protein structure as well as the level of protein structure exhibited by complex proteins such as antibodies. Multiple Choice quaternary; tertiary secondary; tertiary primary; secondary tertiary; quaternary secondary; quaternary

The orientation of all the atoms of a protein in three dimensions represents its tertiary structure. It includes the folding of the polypeptide chains in a way that brings are far apart amino acids of its secondary structure close together. Various segments of a polypeptide chain interact to form tertiary structures and these segments are held together by different kinds of weak interactions.

However, disulfide cross-links between the segments of polypeptide chains also stabilize the tertiary structure of some proteins. Likewise, disulfide bonds also hold the protein subunits of some proteins together and thereby, contribute to the quaternary structure. For example, two light chains of an antibody are joined together by disulfide bonds.

Disulfide bonds are involved in maintaining ________ protein structure as well as the ________ level of protein structure exhibited by complex proteins such as antibodies. Multiple Choice quaternary; tertiary secondary; tertiary primary; secondary tertiary; quaternary secondary; quaternary
