Non-heme iron as ferrous sulfate does not interact with heme iron absorption in humans
(2012)
The absorption of heme iron has been described as distinctly different from that of non-heme iron. Moreover, whether heme and non-heme iron compete for absorption has not been well established. Our objective was to investigate ...
Heme oxygenase 1 overexpression increases iron fluxes in Caco-2 cells
(Sociedad de Biología de Chile, 2006)
Preparation and characterization of iron-alginate beads with some types of iron used in supplementation and fortification strategies
(Elsevier, 2018)
Our work aimed to develop and characterize different alginate beads with either non-heme iron or a blend of heme/non-heme iron. We chose non-heme iron salts such as ferrous sulfate (FS), ferrous ammonium sulfate (FAS), ...
Heme oxygenase 1 overexpression increases iron fluxes in Caco-2 cells
(2006)
Heme oxygenase-1 is a microsomal enzyme that, when induced by stress, protects the cells from oxidative
injury. Heme oxygenase-1 participates in the cleavage of the heme ring producing biliverdin, CO and ferrous
Fe. The ...
The effect of proteins from animal source foods on heme iron bioavailability in humans
(Elsevier, 2016)
Forty-five women (35-45 year) were randomly assigned to three iron (Fe) absorption sub-studies, which measured the effects of dietary animal proteins on the absorption of heme Fe. Study 1 was focused on heme, red blood ...
HmuS and HmuQ of Ensifer/Sinorhizobium meliloti degrade heme in vitro and participate in heme metabolism in vivo
(Springer, 2016-04)
Ensifer meliloti is a nitrogen-fixing symbiont of the alfalfa legume able to use heme as an iron source. The transport mechanism involved in heme acquisition in E. meliloti has been identified and characterized, but the ...
The Effect of Plant Proteins Derived from Cereals and Legumes on Heme Iron Absorption
(MDPI AG, 2015)
The aim of this study is to determine the effect of proteins from cereals and legumes on heme iron (Fe) absorption. The absorption of heme Fe without its native globin was measured. Thirty adult females participated in two ...
Heme-iron utilization by Leptospira interrogans requires a heme oxygenase and a plastidic-type ferredoxin-NADP+ reductase
(Elsevier Science, 2014-07)
Background: Heme oxygenase catalyzes the conversion of heme to iron, carbon monoxide and biliverdin employing oxygen and reducing equivalents. This enzyme is essential for heme-iron utilization and contributes to virulence ...
