Describe the general structure of an antibody molecule.

Summary Introduction

To review:

The structure of an antibody molecule.

Introduction:

Antibodies are blood proteins that are secreted and produced by B cells. They are usually large in size, complex Y-shaped molecule that belongs to the class immunoglobulin. The main function of antibodies is to bind with the antigens that invade our body. They recognize the specific molecule of the pathogen through Fab’s variable region.

Explanation

The structure of the antibody has been described below:

The antibodies consist of four polypeptides chains that are made up of two identical heavy chains and two light chains. Each heavy and light chain consists of a variable region at the N terminal end. N-terminal end of the antibody is crucial for antigen binding. These antigen-binding domains are known as paratopes or CDR (complementary-determining regions)...
