Molybdenum intake influences molybdenum kinetics in men.
The objectives of this study were to determine physiologic adaptations that occur when humans are exposed to a wide range of molybdenum intake levels and to identify the pathways that are influenced by dietary intake. Four males consumed each of 5 daily molybdenum intakes of 22, 72, 121, 467, and 1490 microg/d (0.23, 0.75, 1.3, 4.9, and 15.5 micromol/d) for 24 d each. During each treatment peri...
متن کاملPlasma molybdenum reflects dietary molybdenum intake.
The relationship between plasma molybdenum (Mo) and dietary intake has not been investigated in humans. We developed an isotope dilution method to determine molybdenum in 0.5 mL blood plasma by ICP-MS and conducted a study to determine the effect of dietary intake on plasma molybdenum. Twelve young men consumed a very low Mo diet (22 microg/day) for 24 days while confined to the WHNRC metabolic...
متن کاملMolybdenum enzymes.
There are many molybdenum-containing enzymes distributed throughout the biosphere. The availability of molybdenum to biological systems is due to the high water solubility of oxidized forms of the metal. Molybdenum enzymes can be grouped on the basis of the structure of the metal centre. Three principal families of enzyme exist, with active sites consisting of (ppt)MoOS(OH) (the molybdenum hydr...
متن کاملMolybdenum Oxides vs. Molybdenum Sulfides: Geometric and Electronic Structures
In light of the recent attention MoS2 has received regarding its possibilities for use in the photocatalytic evolution of H2, we have conducted a comparative computational investigation of some key properties that determine water reactivity such as the molecular structure and water adsorption properties of molybdenum oxide and sulfide clusters. Using density functional theory methods, we have f...
متن کاملRotational barrier of a molybdenum-molybdenum quadruple bond.
The synthesis and characterization of molybdenum(II) porphyrin dimers containing unbridged metal-metal quadruple bonds are presented. Variable temperature 300 MHz (1)H NMR studies of meso-substituted derivatives provide novel solution evidence for both the existence of quadruple bonds and for a barrier to rotation about the metal-metal bonds in these complexes. The activation energy for this ro...
