Identification and characterization of the iron compounds in bone marrow by means of Mössbauer spectrometry.

Abstract: In order to determine and to demonstrate the cellular iron molecular states in hematopoietic bone marrow, direct investigations were performed by means of different and complementary spectroscopic techniques: optical absorption, electron spin resonance and Mossbauer spectrometry. In fact, the latter appears to have been the most informative. In addition to the hemoglobin forms, five- and six-coordination ligand protoporphyrins IX (monomeric and polymeric stacking, respectively) were observed. A small amount of non-hemic high-spin iron III storage component (ferritin) was measured. No diferric transferrin was detected. A ferrous compound was also observed and attributed to the mitochondrial iron pool.
