Definitions for "Magnesium"
Found in muscle tissue and is involved in many energy producing reactions in the body. Prevents heart arhythmias, associated with regulation of body temperature, neuromuscular contraction and synthesis of protein.
is second only to potassium in terms of concentration within the individual cells of the body. Magnesium's primary function is to activate enzymes. Approximately 60% of magnesium in the body is found in bone, 26% in muscle, and the remainder in soft tissue and body fluids. Metabolically active tissues such as the brain, heart, liver, and kidneys have the highest concentration of magnesium and depend on magnesium's critical role in energy production. Low magnesium levels can result in muscle spasms and weakness and may be connected to high blood pressure, depression and risk of heart attack. Most Americans consume a low magnesium diet because their diet is high in refined foods, meat, fish, dairy products, and the more commonly eaten fruits, which are all quite low in magnesium. Dietary sources of magnesium are tofu, legumes, seeds, nuts, whole grains, and green leafy vegetables.
One of the important plant nutrients. It is known to stimulate the assimilation of the key plant nutrient: phosphorus.
A light silver-white metallic element of atomic number 12, malleable and ductile, quite permanent in dry air but tarnishing in moist air. It burns, forming (the oxide) magnesia, with the production of a blinding light (the so-called magnesium light) which is used in signaling, in pyrotechny, or in photography where a strong actinic illuminant is required. Its compounds occur abundantly, as in dolomite, talc, meerschaum, etc. Symbol Mg. Atomic weight, 24.305. Specific gravity, 1.75.
Weighing about a third less than aluminum, this metal is used where low weight is required. A magnesium road wheel was optional for Corvettes starting in 1997.
Light silvery-white malleable metal.
One of the nine macronutrients. Most soils have sufficient supplies of magnesium to ensure healthy plants, but sandy soils may be deficient. In addition to activating enzymes that form oils, starch, and fats, magnesium also is a component of the chlorophyll molecule. Symptoms of magnesium deficiency appear first on older growth in the form of interveinal chlorosis. New growth is reduced or stunted.
Secondary macronutrient critical for plant growth, as it is the central metal in chlorophyll. Magnesium forms a divalent soil cation.
Magnesium is essential for growth of leaves and roots. You are only likely to come up against a deficiency if the land you are using is very light and has not been manured for some years. Another possible cause is too much chalk or lime in the soil, which interferes with absorption.

Mg2+ ions stabilize the negative charges of the oxygen atoms on phosphate groups during the PCR reaction. Often these ions are obtained from MgCl2. R. Saiki reports: "The component with the most dramatic effect on specificity is MgCl2: optimal levels will often vary depending on the sequence being amplified and the nature of the primers. In most cases best results with genomic targets are obtained in reactions with 0.5-1.0 mM free magnesium" Saiki also reports that because dNTPs bind Mg2+ themselves, "the amount of free Mg2+ available for Taq polymerase to bind is the concentration of MgCl2 less the total concentration of dNTPs. pp25-26, Erlich, 1988. (mM=millimolar)
An ion that lowers mash and wort pH but also implants a clinging "bite" to the finished beer.
A dissolved mineral in pool water. Contributes to water hardness and turbidity.
Hardness Magnesium dissolved in water contributes to total water hardness. Forms scale in high amounts.
One of the elements in the earth's crust, the compounds of which when dissolved in water make the water hard. The presence of magnesium in water is a factor contributing to the formation of scale and insoluble soap curds which identify hard water.
