We present empirical energy calculations on the binding of thyroxine analogs to the plasma protein prealbumin. The results of the calculations suggest a stronger binding affinity for the L isomer than the D, consistent with observed binding affinities. These calculations allow us to rationalize the significantly stronger binding of des‐NH 3 + than des‐COO − analogs of the hormone to the protein.
