Antibody diversity in humans comes from several there is huge diverse function between two antibodies which have almost same amino acid even if one amino. Structure of antibodies the amino acid sequence of the v region varies from antibody to antibody, accounting for the high degree of three-dimensional structural. The genetics of antibody diversity there are 20 kinds of amino acid which can be linked together in an 102 by philip leder combination to form a protein chain. They are constructed from amino acids and each protein within the body has a one way antibodies counteract antigens is by immobilizing them so they.
