WebOct 15, 2024 · The human body only makes five types of Immunoglobulins: IgG, IgM, IgA, IgD & IgE. These immunoglobulins protect the body from multiple types of antigens. All antibodies are different based on their amino acid sequence in the constant region, structure (monomer, pentamer, and dimer), short-life in the blood, site, and immunological properties. WebAntibodies 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. The amino acid sequence in the tips of the "Y" varies greatly among different antibodies.
