hydroxyapatiten.

/hʌɪˌdrɒksɪˈapətʌɪt/

Etymology: < hydroxy- comb. form + apatite n.

Calcium phosphate hydroxide, ideally [Ca₃(PO₄)₂]₃.Ca(OH)₂, which occurs as a rare mineral of the apatite group (in which hydroxyl replaces all or most of the fluorine of the commoner fluorapatite), and which is the principal inorganic constituent of tooth enamel and bone.

1912 Bull. U.S. Geol. Surv. No. 509. 100 The three formulas developed are repeated here... To the list are added those of apatite, both the fluorapatite and the hypothetical hydroxyapatite... Hydroxyapatite, 9CaO.3P₂O₅.CaO.H₂O.

1917 Jrnl. Chem. Soc. 111 638 The mineral constituents of bone consist in the main of hydroxyapatite, (Ca₃P₂O₈)₃Ca(OH)₂, mixed with a certain amount of calcium carbonate.

1962 W. A. Deer et al. Rock-forming Minerals V. 333 The hydroxyapatite..in talc schist and the fluor-hydroxyapatite in chlorite schist, both from a serpentinite near Holly Springs, Georgia, are considered to be metamorphic in origin.

1964 A. White et al. Princ. Biochem. (ed. 3) xli. 781 It seems likely that in bone, divalent cations other than Ca⁺⁺ can replace Ca⁺⁺ in the hydroxyapatite crystal lattice, whereas anions other than phosphate and hydroxyl may be adsorbed on the vast areas of surface offered by the minute crystals.

1971 Physics Bull. July 411/1 The enamel of a tooth is composed of hydroxyapatite crystals in prismatic form.
