Question

Describe the basic structure of an antibody with the help of suitable diagram.

Answer 1

Antibodies are immune system-related proteins called immunoglobulins. Each antibody consists of four polypeptides– two heavy chains and two light chains joined to form a "Y" shaped molecule.

Answer 2

Answer:

Antibody generally have  Y shaped structure.

Explanation:

Antibodies are the most important proteins secreted by the various cells of our immune system such as B lymphocyte cell.Antibody generally have y shaped structure.

                Antibody contain 2 heavy chain and 2 light chains.There are both variable region and constant region in an Antibody molecule.When an antibody is digested with  a proteolytic enzyme Papain it generates two antigen binding fragment and a Fc fragment.The antigen binding fragment present in the variable region and this fragment  interract with antigen.There are 5 isotypes of Antibody they are as follows

1 Gamma represent IgG

2 delta represent IgD

3  epsilon represent IgE

4 alpha represent IgA

5 mu   repesent IgM
