Verified step by step guidance1
Understand that immunoglobulins, also known as antibodies, are glycoproteins produced by plasma cells. They play a crucial role in the immune response by identifying and neutralizing pathogens such as bacteria and viruses.
Recognize the five main classes of immunoglobulins in humans: IgA, IgD, IgE, IgG, and IgM. Each class has a distinct role in the immune system.
Review the list of options provided in the problem: IgM, IgH, IgG, IgE, and IgD.
Identify that IgH is not a recognized class of immunoglobulins. Instead, IgH refers to the heavy chain of an immunoglobulin molecule, which is a component of the antibody structure but not a class itself.
Conclude that the option 'IgH' is the correct answer to the question, as it is not an immunoglobulin class.
