Kalciumfoszfát

Kalciumfoszfát, also known as calcium phosphate, refers to a group of chemical compounds containing calcium cations and phosphate anions. The most common form encountered in everyday life and biology is hydroxyapatite, which is the primary mineral component of bone and teeth. It has the chemical formula Ca5(PO4)3(OH). Other forms include dicalcium phosphate (CaHPO4) and tricalcium phosphate (Ca3(PO4)2).

In nature, calcium phosphates are abundant. They are found in rocks, soil, and are essential for living organisms. In the human body, calcium and phosphate ions play crucial roles in bone and tooth structure, muscle contraction, nerve function, and blood clotting. Dietary intake of calcium and phosphate is vital for maintaining these physiological processes. Common food sources rich in calcium include dairy products, leafy green vegetables, and fortified foods, while phosphate is found in meat, fish, nuts, and dairy.

Industrially, calcium phosphates have various applications. They are used as food additives, serving as anticaking agents, leavening agents, and nutritional supplements. In medicine, they are employed in bone grafts and dental materials due to their biocompatibility and ability to integrate with bone tissue. They also find use in fertilizers and as abrasives in toothpastes. The specific properties and uses of calcium phosphate depend on its exact chemical form and crystalline structure.
