Magnesium is a chemical element; it has symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity.
Treating the solution of different soluble magnesium salts with alkaline water induces the precipitation of the solid hydroxide Mg(OH) 2: Mg 2+ + 2 OH − → Mg(OH) 2. As Mg 2+ is the second most abundant cation present in seawater after Na +, it can be economically extracted directly from seawater by alkalinisation as described here above.
The citrate is the least expensive soluble (high bioavailability) oral magnesium salt available in supplements, with 100 mg and 200 mg magnesium typically contained per capsule, tablet or 50 mg/mL in solution. [26]
Magnesium glycinate has been studied with applicability to patients with a bowel resection [1] or pregnancy-induced leg cramps. [2] Less scientific research exists on magnesium glycinate in therapeutic applications than other more common forms of magnesium salt such as magnesium chloride, oxide or citrate.
Magnesium gluconate is a compound with formula MgC 12 H 22 O 14.It is the magnesium salt of gluconic acid.. According to one study, magnesium gluconate showed the highest level [dubious – discuss] of bioavailability of any magnesium salt which implies its viability as a supplement, although of the 10 salts studied, all increased magnesium levels significantly.
The chemical formula for this compound is Mg(C4H6NO4)2. [7] The structure of magnesium aspartate consists of a central magnesium ion that is chelated, or bound, by two aspartate anions. The aspartate moiety contains a carboxyl group (-COOH), an amino group (-NH2), and a second carboxyl group, forming a dicarboxylic amino acid structure. [1] [7]
Magnesium citrate (3:2) (3 magnesium atoms per 2 citrate molecules), also called trimagnesium dicitrate, trimagnesium citrate, or the ambiguous name magnesium citrate.The substance may come as anhydrous or hydrated salt with varying properties.
The structures of solid magnesium citrates have been characterized by X-ray crystallography.In the 1:1 salt, only one carboxylate of citrate is deprotonated. It has the formula Mg(H 2 C 6 H 5 O 7) 2 The other form of magnesium citrate has the formula Mg(HC 6 H 5 O 7)(H 2 O) 2, consisting of the citrate dianion (both carboxylic acids are deprotonated). [1]
