title: Binding of some meso-tetraphenyl porphyrins with apohemoglobin and methemoglobin.
abstract: Six tetraphenylporphyrins have been studied for their binding with human apohemoglobin and methemoglobin. Four showed binding with apohemoglobin, in a way hemin binds, to form analogs of recondtituted hemoglobin. Five porphyrins bound with methemoglobin, perhaps, through random ionic interaction.
