Antibodies are one of the major players in the adaptive immune response. All antibody molecules consist of two heavy chains and two light chains, and the specific type of heavy and light chain will determine the antigen binding site. In all antibodies, the two heavy chains and the two light chains are identical. Like most proteins, much of their functional capabilities and antigen binding characteristics stem from their three-dimensional structure. Which of the following holds the heavy and light chains together to make the three-dimensional structure of the antibody?
(A) Disulfide bonds
(B) Hydrogen bonds
(C) Ionic bonds
(D) Triple covalent bonds
(E) Van der Waals forces
