Why is the structure of an antibody molecule represented as H2L2? Name any two types of antibodies produced in the human body.

An antibody is a molecule that has four peptide chains out of which two are long chains called heavy chains (H), and the other two are small chains called light chains (L) arranged in ‘Y’ shaped structure. Hence the structure of the antibody molecule is represented as H2L2. Our human body produced many different types of antibodies in our bodies namely IgA, IgM, IgE, IgG, etc.
