Source sentences:
text: Up to now the structure proposed for immunoglobulins consists of a four-chain model referring to the presence of two identical light polypeptide chains (light chains) and two identical heavy polypeptide chains (heavy chains) linked together by disulfide bonds to form a y- or T-shaped macromolecules.
