There are 2 light chains and 2 heavy chains that are attached to each other by chemical bonds. There are 5 types of immunoglobulins – IgG, IgA, IgM, IgD and IgE.
Detailed explanation-2: -IgM immunoglobulins are produced by plasma cells as part of the body’s adaptive humoral immune response against a foreign pathogen.
