Chemical compound
Calcium phosphate is a family of materials and minerals containing calcium ions (Ca2+) together with inorganic phosphate anions. They are used in a variety of applications, including as a component of bone and tooth enamel, in fertilizers, and in food as a leavening agent.
Chemical Composition[edit]
Calcium phosphate compounds are generally composed of calcium cations and phosphate anions. The most common forms include:
- Hydroxyapatite (Ca5(PO4)3(OH)), which is the main mineral component of bone and teeth.
- Tricalcium phosphate (Ca3(PO4)2), used in food and as a supplement.
- Dicalcium phosphate (CaHPO4), used in animal feed and toothpaste.
- Monocalcium phosphate (Ca(H2PO4)2), used in fertilizers and baking.
Biological Role[edit]
Calcium phosphate is a critical component of biological systems. It is the primary mineral found in bone and tooth enamel, providing structural integrity and strength. The mineralization process involves the deposition of calcium phosphate in the form of hydroxyapatite crystals.
Medical Applications[edit]
Calcium phosphate is used in various medical applications, particularly in orthopedics and dentistry. It is used as a bone graft material due to its biocompatibility and ability to promote bone growth. Calcium phosphate cements are also used in surgery to repair bone defects.
Industrial Uses[edit]
In industry, calcium phosphate is used in the production of fertilizers, where it provides essential nutrients for plant growth. It is also used in the food industry as a leavening agent and as a calcium supplement in various products.
Pathological Aspects[edit]
Calcium phosphate can form pathological deposits in the body, such as in kidney stones and arterial calcification. These deposits can lead to various health issues, including impaired kidney function and cardiovascular disease.
