What is the bone crystal name in mineralized bone?

Explanation:
In mineralized bone the stiffness comes from a calcium phosphate crystal that sits within the organic collagen matrix. This mineral is hydroxyapatite, a crystal of calcium phosphate that belongs to the apatite family. So the bone’s crystal phase is calcium phosphate (apatite). In bone, sometimes carbonate can substitute into the hydroxyapatite lattice, giving carbonate-substituted apatite, but the fundamental mineral is calcium phosphate. Calcium carbonate and calcium sulfate aren’t the primary bone minerals, which is why calcium phosphate (apatite) is the correct choice.
