inorganic phosphorus
The most important inorganic phosphate is calcium phosphate, Ca3(PO4)2. It makes up the larger part of phosphate rock, a mineral that is abundantly distributed throughout the world. Ca(H2PO4)2, is a compound produced by treating rock phosphate with sulfuric acid or phosphoric acid, or a mixture of the two.
Hypophosphatemia may be described as low levels of inorganic phosphate in the blood. Phosphate, or phosphorous, is similar to calcium, and is found in your teeth and bones. You need vitamin D in order to absorb phosphate. The kidneys excrete (get rid of) phosphate from our bodies. The normal range for phosphorous is 2.5-4.5 mg/dL.
