The two structural portions of the antibody, i.e. the variable (Fab) and the constant (Fc) fragments, impart distinct biological functions. These functions are outlined as follows: Fab-mediated functions: 1  Antigen recognition â One of the major functions of the Fab region is antigen recognition.2  The immune system generates large number of antibodies that can recognize virtually all possible antigens present in pathogens and their products.
