Webb4 sep. 2024 · The IgMs are essentially five identical IgG ‘Y’ molecules (see Antibody dreaming essay). Think of five ‘synchronised swimmer’ quintuplets in a pool, with their feet together and their hands, the identical Ig variable (v) region binding sites, sticking out. WebbSTRUCTURE OF ANTIBODIES/IMMUNOGLOBULINS Immunoglobulins are glycoproteins comprises of four polypeptide chain: two identical light (L) and two identical heavy (H) chains. Further, L and H chains are subdivided into variable and constant regions. The terms light and heavy refer to molecular weight.
