Immunoglobulin Heavy Chains

Immunoglobulin heavy chains (IgG) are one of two major classes of immunoglobulin antibodies produced by the immune system of humans and animals. They play an important role in protecting the body from infections and other pathogenic agents such as viruses, bacteria and parasites.

IgG heavy chains are long polypeptide chains consisting of more than 400 amino acids. They are the main component of immunoglobulin-G and are responsible for binding to antigens, which can be bacteria, viruses or other foreign substances.

One of the main functions of IgG heavy chains is that they are able to bind to antigen that is located on the surface of target cells. This allows immune cells such as T cells and B cells to recognize the antigen and initiate an immune response.

In addition, IgG heavy chains also provide protection to the body against infections. When antigens enter the body, they bind to the heavy chains of IgG, which leads to the activation of immune cells and the production of antibodies. These antibodies then bind to the same antigens and neutralize their activity, preventing further infection.

However, IgG heavy chains are not the only form of immunoglobulin the body produces. There is also a light class of immunoglobulin - IgM, which also plays an important role in the body's immune defense.

In general, IgG heavy chains are an important component of the immune system, which provides protection to the body against various infections and pathogens.
