Magnesium chemistry and biochemistry

  title={Magnesium chemistry and biochemistry},
  author={Michael E. Maguire and James Allan Cowan},
Magnesium apparently derives its name from Magnesia, a district in the Volos area of Thessaly in northeastern Greece. It was used to refer to any of several minerals ranging from magnesite (magnesium carbonate or ‘magnesia alba’) to magnetite (manganese dioxide or ‘magnesia nigra’) and also magnesia stone (talc or soapstone), a magnesium silicate. However, there are also two ancient towns in Asia Minor named Magnesia from the Greek word magnes used to refer to the magnetic iron ore discovered…

The central role of Mg2+ in the function of ribozymes and its ‘archaic’ position in ribosomes, and the fact that magnesium generally has coordination properties different from other cations, suggests that the inorganic chemistry of magnesium had a key position in the first chemical processes leading to the origin and early evolution of life.
Determination of magnesium salinity in Belozem region, Bulgaria.
Salinisation is an important soil-forming process (primary or secondary), characterized by an excess of water-soluble salts and/or exchangeable sodium. The amount of exchangeable magnesium is also
Microbially Induced Magnesium Carbonate Precipitation and its Potential Application in Combating Desertification
Abstract This study investigated the reaction processes of microbially induced magnesium carbonate precipitation (MIMP) with Sporosarcina pasteurii (ATCC 11859) and evaluated its feasibility for
Synthesis and Chemical and Biological Evaluation of a Glycine Tripeptide Chelate of Magnesium
The synthesis, chemical and physical characterization, and cellular uptake of a magnesium triglycine chelate (MgG3), an octahedral complex with extraordinary water solubility and improved cellular uptake in CaCo-2 cells than select commonly used magnesium supplements are discussed.
Dissolution of Mg Fertilizer and Its Availability in Cassava in Tropical Upland Soils
ABSTRACT Effect of magnesium chloride (MgCl2) and dolomite on magnesium (Mg) availability cassava was observed by a pot experiment under greenhouse condition in three Paleustults. Their water
Comparative spectroscopic analysis of nordihydroguaiaretic acid and related natural products to inhibition of calcium oxalate calculi
The prevalence of urolithiasis is still increasing worldwide. The goal of this study is to achieve a better understanding, from a comparative spectroscopic perspective, of the differences provided by
Timeline (Bioavailability) of Magnesium Compounds in Hours: Which Magnesium Compound Works Best?
Magnesium acetyl taurate was rapidly absorbed, able to pass through to the brain easily, had the highest tissue concentration level in the brain, and was found to be associated with decreased anxiety indicators.
A study on the influence of sodium carbonate concentration on the synthesis of high Mg calcites
Well crystallized high Mg calcites in pure phase with Mg contents higher than 50 mol%, so-called protodolomite, have not been synthesized in the laboratories to our knowledge. In this work, the
Evaluation of Inorganic Elements in Herbal preparation by FAAS and FES
In this study four inorganic elements i.e. sodium, potassium, calcium and magnesium were estimated in eleven locally available herbal preparations used as sex stimulants using Flame Atomic Absorption


Doctor Nehemiah Grew (1641-1712) and the Epsom salts.
The purgative effect of the waters of Epsom, in southern England, was first discovered in the early seventeenth century. Epsom subsequently developed as one of the great English spas where high
Brief Reviews: Magnesium in Heart Muscle
There are compelling reasons for reexamining the role of Mg in heart muscle at this time, and work with subcellular model systems indicates that Mg participates in many of the most vital oxidative, synthetic, and transport processes of the myocardial cell.
Effect of magnesium complexation by fluoroquinolones on their antibacterial properties
It appeared that, in every case, an impairment of accumulation is responsible for the increase in the MICs observed upon the addition of magnesium.

In immature rats uptake of radioactive magnesium by the testes was slightly faster than in the mature animals and net decay of plasma activity was faster but there were no other significant differences.
Cation Hexaammines Are Selective and Potent Inhibitors of the CorA Magnesium Transport System*
Results demonstrate that cation hexaammines are potent and highly selective inhibitors of the CorA Mg2+ transport system and further indicate that the initial interaction of theCorA transporter is with a fully hydrated Mg 2+ cation.
Is the binding of magnesium (II) to calmodulin significant? An investigation by magnesium-25 nuclear magnetic resonance.
25Mg NMR was used to study the binding of Mg2+ to apo-CaM, CaM.Ca2(2)+ and TR1C, and the association constant (Ka) and off-rate (koff) was calculated as in the case of Ca2+ binding.

This review covers two methods, in vivo nuclear magnetic resonance (NMR) and fluorescence spectroscopy, which have provided useful means for the determinations based on ATP measurements, and more recently developed fluorinated or fluorescent indicators.
Cloning of the mgtE Mg2+ transporter from Providencia stuartii and the distribution of mgtE in gram-negative and gram-positive bacteria
The sequence of the cloned P. stuartii DNA revealed the presence of a single open reading frame, which was shown to express a protein with a gel molecular mass of 37 kDa in agreement with the deduced size of 34 kDa, and was homologous to MgtE, a newly discovered Mg2+ transport protein from the gram-positive bacterium Bacillus firmus OF4.
