Calcium citrate is the calcium salt of citric acid. It is commonly used as a food additive , usually as a preservative, but sometimes for flavor. In this sense, it is similar to sodium citrate. Calcium citrate is also found in some dietary calcium supplements (e.g. Citracal or Caltrate). Calcium makes up 24.1% of calcium citrate (anhydrous) and ...
It is the calcium salt of citric acid and malic acid with variable composition. Calcium citrate malate's bioavailability stems from its water-solubility and its method of dissolution. When dissolved, it releases calcium ions and a calcium citrate complex. Calcium citrate malate is similar to calcium malate and other calcium salts.
Magnesium citrate: C 12 H 10 Mg 3 O 14 [11] Citrus based beverages like lemon juice and orange juice may raise urine citrate, but much of the citrate is citric acid; without a cation like sodium, potassium or magnesium these beverages will have less effect on urine chemistry and therefore not aid in prevention of kidney stones as alkali citrate ...
6 Mg(OH) 2 + 6 Cl 2 → 5 MgCl 2 + Mg(ClO 3) 2 + 6 H 2 O. Magnesium perchlorate is a white powder that is easily soluble in water, which can be obtained by the reaction of magnesium oxide and perchloric acid. The hexahydrate crystallizes from the solution, and then it is dried with phosphorus pentoxide in a vacuum at 200~250 °C to obtain the ...
Ptolemy's theorem states that the sum of the products of the lengths of opposite sides is equal to the product of the lengths of the diagonals. When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin(α + β) = sin α cos β + cos α sin β.
Caltrate [1] is a brand name calcium supplement sold by Haleon.. The brand was originally owned by Pfizer (formerly Wyeth) and GSK and in Japan by Hisamitsu Pharmaceutical.. The Caltrate brand is supplied in many different formulas; calcium carbonate (NOT calcium citrate) is the common ingredient serving as the calcium supplement source. [2]

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]
