- Antibodies
- Structure
- variable region which has a shape specific to the shape of the antigen
- constant region which is the same for all the antibodies
- Hinged region to allow flexibility to take more/less antigen
- Disulfide bridge to hold the polypeptides together
- Function
- Opsonisation. Bind to the pathogen's antigen and use its end region to signal phagocyte for phagocytosis.
- Agglutination. Using each binding site to bind a different pathogen, the antibodies crosslink into a big clump and easily phagocytosed.
- Anti-toxins. Some antibodies bind to the toxins released by the pathogen and renders them harmless.
