Crystalline Leghemoglobin. VI. The Comparison of the Two Main Components by Tryptic Peptide Pattern Analysis.

Abstract
Tryptic peptides of the 2 main components of hemoglobin were analyzed in order to elucidate structural differences and to determine whether 1 is a precursor of the other or if the 2 components are synthesized by 2 systems under different genetic control. There are major differences in the electrophoretic patterns, which argue for the acceptance of the theory of separate synthesis, separate genetic control.
