      Unbelievably small (unless your a quantum physicist in which case HUGE)

      Individual molecules of insulin are 100 x bigger than salt (which has a molecular weight of 58)

      in 1 gram of salt there would be about
      10000000000000000000000 molecules of salt

      1 g or insulin would have about
      100000000000000000000 insulin molecules!

      so very small.
