An antibody

Describe the structure of an antibody. (Module 20.18A)

An antibody molecule consists of two parallel pairs of polypeptide chains: a pair of long, heavy chains and a pair of short, light chains. Each chain contains both constant segments and variable segments. The constant segments of the heavy chains form the base of the antibody molecule; the free tips of each of the two variable segments form the antigen-binding sites.`
