human low-density lipoproteins ( ldl ) and very-low-density lipoproteins ( vldl ) also bound to these sites ( kd = 41 micrograms protein/ml , approx . 6.7 x 10 ( -8 ) m for ldl , and kd = 5.7 micrograms protein/ml , approx . 7.0 x 10 ( -9 ) m for vldl ) , but this observation must be considered in light of the fact that the normal circulating concentrations of these lipoproteins are much lower than those of hdl .
