What is a primary mineral component in bones and teeth?

The primary mineral component in bones and teeth is hydroxyapatite, which is a calcium phosphate mineral with the chemical formula Ca5(PO4)3(OH). It forms the hard and rigid matrix of bones and teeth, providing them with strength and structure. Hydroxyapatite crystals are arranged in a specific way to give bones and teeth their unique properties. In addition to calcium and phosphate, hydroxyapatite also contains small amounts of other minerals, such as magnesium, sodium, and carbonate, which contribute to its overall composition and properties.
