Antibodies, which are Y-shaped glycoproteins, bind to specific antigens on pathogens or toxins to neutralize them. Composed of polypeptide chains, they form antigen-antibody complexes and have a hinge region providing flexibility to bind multiple antigens.
Los anticuerpos, que son glicoproteínas en forma de Y, se unen a antígenos específicos en patógenos o toxinas para neutralizarlos. Compuestos por cadenas de polipéptidos, forman complejos antígeno-anticuerpo y poseen una región bisagra que proporciona flexibilidad para unirse a múltiples antígenos.

| Back | Antibodies (Y shaped glycoproteins called immunoglobulins) bind to specific antigen on pathogen or toxin that has triggered immune response, specific antibody for each antigen, made up of 2 identical long polypeptide chains (heavy chains) and 2 shorter identical chains (light chains), chains held by disulfide bridges (also polypeptide chains), antibody binds to antigen via lock and key, forming antigen - antibody complex, hinge region provides flexibility so it can bind 2 seperate antigens, one at each site |
