Mössbauer spectroscopy of the ferritin showed that it contains iron cores based on the ferrihydrite (5Fe2O3·9H2O) structure consistent with previously reported electron diffraction data [T.G. St. Pierre, K.C. Tran, J. Webb, D.J. Macey, B.R. Heywood, N.H. Sparks, V.J. Wade, S. Mann and P. Pootrakul, Biol. Metals, 4 (1991) 162]. Cores in the crude hemosiderin are mainly of the ferrihydrite type but a significant amount have a defect goethite (α-FeOOH) structure. These data are interpreted in terms of the long-term deposition of iron in the pancreas in this iron overload pathology.Mahidol UniversityChemistryMaterials ScienceArticleSCOPUS
