Responses of plants to iron, zinc and copper deficiencies.
Iron, copper and zinc are essential metals for cell metabolism. Plants have evolved different schemes to efficiently mobilize low-solubility nutrients such as metals from their environment and to transport them between organs. In this review we highlight the divergences and convergences of the iron, copper and zinc uptake, transport and homoeostatic pathways.
متن کاملAssociation between plasma zinc concentration and zinc kinetic parameters in premenopausal women.
The objective of this study was to measure relationships between plasma zinc (Zn) concentrations and Zn kinetic parameters and to measure relationships of Zn status with taste acuity, food frequency, and hair Zn in humans. The subjects were 33 premenopausal women not taking oral contraceptives and dietary supplements containing iron and Zn. Main outcomes were plasma Zn concentrations, Zn kineti...
متن کاملZinc, iron, copper, and magnesium concentrations in tissues of rats fed various amounts of zinc.
An experiment was conducted with rats to determine the effects on the tissue concentrations of Zn, Fe, Cu, and Mg of feeding various amounts of zinc. The rats were pair-fed one of the following diets for four weeks: Diet A, a zinc-deficient diet; a diet containing the recommended amoun of zinc (diet A plus 55 microgram of zinc per gram of diet), or diet A plus 550 microgram zinc per gram of die...
متن کاملIncreased retention of orally administered zinc and raised blood cell zinc concentrations in iron-deficient rats.
I. Rats were made severely iron-deficient by feeding with Fe-deficient diets, which contained adequate amounts of zinc. 2. Ten days after an oral dose of 250 ,ug %n the Fe-deficient rats had retained 17 yo whereas control rats had retained only 8 yo of the dose. 3. When unlabelled Zn was given intravenously to the Fe-deficient and control rats there was a reduction in retention of the orally ad...

Objective. To describe the micronutrient nutritional status of a national sample of 1-11 year old Mexican children surveyed in 2006 in National Health and Nutrition Survey (ENSANUT 2006) and their association with dietary and sociodemographic factors. Materials and methods. Serum samples were used (n=5 060) to measure the concentrations of ferritin, transferrin receptor, zinc, copper and magnes...
