Immunoglobulin (Ig) refers to globulin with antibody (Ab) activity or chemical structure, which is similar to antibody molecule. Immunoglobulin is a tetrapeptide chain structure, which is composed of two identical light chains and two identical heavy chains connected by disulfide bonds between chains.

Immunoglobulin is divided into five categories, namely immunoglobulin G(IgG), immunoglobulin A(IgA), immunoglobulin M(IgM), immunoglobulin D(IgD) and immunoglobulin E(IgE).

Introduction to immune system:

The immune system consists of immune tissues, organs, immune cells and immunocompetent molecules. Immunoglobulin is an immunocompetent molecule, which includes immune cell membrane molecules, such as antigen recognition receptors, differentiation antigens, major histocompatibility molecules and some other receptor molecules.

It also includes molecules synthesized and secreted by immune cells and non-immune cells, such as immunoglobulin molecules, complement molecules and cytokines. Immunoglobulin is a concept in chemical structure. The chemical basis of all antibodies is immunoglobulin, but immunoglobulin has no antibody activity.
