Heme and Tissue Iron
1. A method is described for estimating the heme in yeast and bees' muscles as pyridine hemochromogen. 2. The difficulties of the method are discussed. 3. The heme as given by the pyridine method is responsible for about 40 per cent of the total iron.
متن کاملModeling non-heme iron proteins.
Synthetic modeling studies of non-heme iron proteins continue to contribute to our understanding of the mechanism of these proteins. Recently, mononuclear Fe(IV)=O complexes have been prepared and characterized to model the same species that are proposed to be the reactive intermediates in reactions involving mononuclear non-heme iron proteins. Generation of such species for the oxidation of or...
متن کاملRed cells, hemoglobin, heme, iron, and atherogenesis.
OBJECTIVE We investigated whether red cell infiltration of atheromatous lesions promotes the later stages of atherosclerosis. METHODS AND RESULTS We find that oxidation of ferro (FeII) hemoglobin in ruptured advanced lesions occurs generating ferri (FeIII) hemoglobin and via more extensive oxidation ferrylhemoglobin (FeIII/FeIV=O). The protein oxidation marker dityrosine accumulates in compli...
متن کاملNon-heme iron enzymes: contrasts to heme catalysis.
Non-heme iron enzymes catalyze a wide range of O(2) reactions, paralleling those of heme systems. Non-heme iron active sites are, however, much more difficult to study because they do not exhibit the intense spectral features characteristic of the porphyrin ligand. A spectroscopic methodology was developed that provides significant mechanistic insight into the reactivity of non-heme ferrous act...
متن کاملAdaptation in iron absorption: iron supplementation reduces nonheme-iron but not heme-iron absorption from food.
BACKGROUND Results of cross-sectional studies suggest that in healthy people, iron absorption adapts to meet physiologic needs and stabilize iron stores, but this has not been adequately tested in longitudinal studies. OBJECTIVE We tested whether heme- and nonheme-iron absorption decrease in response to increased iron intake and whether iron stores reach a steady state. DESIGN In a randomiz...
