An immunoglobulin G (IgG) antibody is a quaternary protein structure consisting of two identical light (L) polypeptide chains and two identical heavy (H) polypeptide chains.
The number of amino acids in each of the heavy chains is 108.411%108.411\%108.411% greater than in each of the light chains. Each light chain contains 214214214 amino acids.
Calculate the total number of amino acids in this IgG antibody molecule. Give your answer to the nearest whole number.
