Calcium sails

Various calcium sails and organic compounds lull into this category of dietary supplements and are frequently used in feeds and foods. Some of the more Important additives include calcium carbonate, calcium glycerophosphate, calcium phosphate (di- and monobasic), calcium pyrophosphate, calcium sulfate, and calcium pantothenate.

In ihe mammalian body, calcium is required to insure the integrity and permeability of cell membranes. 10 regulate nerve and muscle excitubiliiy. to help maintain normal muscular contraction, and to assure cardiac rhvthmicity. Calcium plays an essential role in several of ihe enzymatic steps involved in blood coagulation and also activates certain other enzyme-catalyzed reactions not involved in any of ihe foregoing processes. Calcium is ihe niosi important element of bone sail. Together with phosphate and carbonate, calcium confers on bone most of its mechanical and structural properties. 

The soils of humid regions are commonly low in calcium thus, ground limestone usually is applied tu add the clement, reduce the toxicity uf aluminum and manganese, and correct soil acidity. The soils of dry areas are frequently rich in calcium. There is little evidence to indicate a strung relationship between human nutrition and calcium excesses or deficiencies in the soil. Even wiih farm livestock, most calcium deficiencies are not related to levels of av ailable calcium in the sail. The reason for this anomaly is evident when one examines some of the controls over the movement of calcium in Ihe food chain. 

CARBIDES. A binary solid compound of carbon and another element. The most familiar carbides are those of calcium, tungsten, silicon, boron, and iron (cemcntitc) Two factors have an important bearing on the properties of carbides (1) the difference in electronegativity between carbon and the second elemenl. and (2) whether the second element is a transition metal. Saltlike carbides of alkali metals are obtained by reaction with acetylene. Those ohlained from silver, copper, and mercury sails are explosive. See also Carbon and Iron Metals, Alloys, and Steels.

Phosphorus. Eightv-tive percent of the phosphorus, the second most abundant element in the human body, is located in bones and teeth. Whereas there is constant exchange of calcium and phosphorus between bones and blood, there is very little turnover in teeth. The Ca P ratio In hones is constant at about 2 1. Every tissue and cell conlains phosphorus, generally as a sail nr ester of mono-, di-. or tribasic phosphoric acid, as phospholipids, or as phosphorylaled sugars. Phosphorus is involved in a large number and wide variety of metabolic functions. Examples arc carbohydrate metabolism, adenosine triphosphate (ATP) from fatty acid metabolism, and oxidative phosphorylation. 

Of the cations (counterions) associated with polar groups, sodium and potassium impart water solubility, whereas calcium, barium, and magnesium promote oil solubility. Ammonium and substituted ammonium ions provide both water and oil solubility. Tnethanolammonium is a commercially important example. Sails (anionic surfaclanls) of these ions are often used in emulsification. Higher ionic strength of the medium depresses surfactant solubility. To compensate for the loss of solubility, shorter hydrophobes are used for application in high ionic-strength media.
