Apatites in biological systems
TL;DR: The observations made in 1926 that tooth enamel, dentine and bone had x-ray diffraction patterns similar to those of mineral apatltes coupled with the chemically analyzed calcium and phosphate contents, led to the conclusion that the principal inorganic constituents of bone and tooth are basically calcium hydroxyapatite, idealized as CaI0(PO~)6(OH)2 (1,2).

Urinary calcium excretion in human beings.
TL;DR: The solubility of calcium monohydrogen phosphate appears to determine the precipitation of calcium phosphates from aqueous solutions; this salt then undergoes transformation to apatites, which are the principal cation in human beings.
