Chapter 30, Problem 21P

Interpretation Introduction

Interpretation:

In the immunoglobulin structure, the “hinge region” joins the stem of the y to the arms. The hinge region can be cleaved by a specific enzyme to yield one ${\text{F}}_{\text{C}}$ fragment and two ${\text{F}}_{\text{ab}}$ fragments. Discuss which two kinds of fragments can interact with an antigen.

Concept Introduction:

Antigen can be defined as a foreign body that invades the body. They simulate the immune system of the body to produce antibodies. Antibodies are glycoproteins generated by plasma cells when the body is exposed to any antigen.
