Which of the following is true of the structure of immunoglobulins?

Question

Quizplus · Accepted Answer

Immunoglobulins, also known as antibodies, are composed of two identical light chains and two identical heavy chains, making a total of four polypeptide chains. The light chains are shorter and have a molecular weight of about 25 kDa, while the heavy chains are longer and have a molecular weight of about 50 kDa. The heavy chains are further classified into five different types: alpha, gamma, delta, epsilon, and mu. Each antibody molecule has two identical heavy chains, which can be of the same type or different types, and two identical light chains.
