Antibodies, or immunoglobulins, are essential proteins that form the backbone of the immune system, defending the body against pathogens. The five distinct classes—IgM, IgG, secretory IgA, IgE, and IgD—each play unique roles in immunity, with variations in structure and function that cater to different immune needs. This exploration of their characteristics, from molecular weight to specific functions, provides a deeper understanding of how they protect the body and support overall health. Recognizing these differences aids in appreciating the complexity and adaptability of the immune response.
