Calcium phosphate is the name given to a family of minerals containing calcium ions (Ca2+) together with orthophosphates (PO43-), metaphosphates or pyrophosphates (P2O74-) and occasionally hydrogen or hydroxide ions. Calcium dihydrogen phosphate (also called mono-calcium orthophosphate) Ca(H2PO42 is a chemical compound Dicalcium phosphate, also known as calcium monohydrogen phosphate is a Dibasic Calcium phosphate. ΔfH0liquid -9998 kJ / mol ΔfH0solid A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition a highly ordered atomic structure and specific Calcium (ˈkælsiəm is the Chemical element with the symbol Ca and Atomic number 20 An ion is an Atom or Molecule which has lost or gained one or more Valence electrons giving it a positive or negative electrical charge In Chemistry, the Anion, the Salts and the Esters of Pyrophosphoric acid are called pyrophosphates. Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 In Chemistry, hydroxide is the most common name for the diatomic Anion OH− consisting of Oxygen and Hydrogen Seventy percent of bone is made up of hydroxylapatite, a calcium phosphate mineral. Hydroxylapatite, also called hydroxyapatite, is a Mineral. It is a naturally occurring form of calcium Apatite with the formula Ca5(PO43(OH Tooth enamel is also largely calcium phosphate. Tooth enamel is the hardest and most highly mineralized substance of the body and with Dentin, Cementum, and dental pulp is one of the four major
Uses
For the production of phosphoric acid and fertilizers, for example in the Odda process. Phosphoric acid, also known as orthophosphoric acid or phosphoric(V acid, is a mineral (inorganic acid having the Chemical formula Fertilizers ( also spelt fertiliser are chemical compounds given to Plants to promote growth they are usually applied either through the soil for uptake by plant The nitrophosphate process (also known as the Odda process) was a method for the industrial production of Nitrogen Fertilizers invented by Erling Johnson Overuse of certain forms of calcium phosphate can lead to nutrient-containing surface runoff and subsequent adverse effects upon receiving waters such as algal blooms and eutrophication. A nutrient is food or chemicals that an organism needs to live and grow or a substance used in an organism's metabolism which must be taken in from its environment Surface runoff is a term used to describe when soil is infiltrated to full capacity and excess Water, from Rain, Snowmelt, or other sources flows An algal bloom is a rapid increase in the population of Algae in an aquatic system Eutrophication is an increase in chemical Nutrients -- typically compounds containing Nitrogen or Phosphorus -- in an Ecosystem, and may occur
Calcium phosphate is also a raising agent, with E number E341. E numbers are number codes for Food additives and are usually found on Food labels throughout the European Union. It is also used in cheese products.
It is also used as a nutritional supplement. There is some debate about the different bioavailabilities of the different calcium salts. In Pharmacology, bioavailability is used to describe the fraction of an administered Dose of unchanged drug that reaches the Systemic circulation, one of
It is used in a variety of dental products for remineralization. In Biogeochemistry, remineralisation refers to the transformation of Organic molecules to Inorganic forms typically mediated by biological activity
Another practical application of the compound is its use in gene transfection of cells. Transfection is the process of introducing nucleic acids into cells by non-viral methods. It is not too well understood, but the calcium phosphate precipitate and DNA form a complex that is thought to help the DNA enter the cell.
