Detailed explanation-1: -The inorganic component is primarily crystalline hydroxyapatite: [Ca3(PO4)2]3Ca(OH)2.
Detailed explanation-2: -So the correct answer is ‘Calcium phosphate’.
Detailed explanation-3: -Inorganic Components:-They are mineral salts, mainly Hydroxyapatite (a cristallized form of tricalcium phosphate), some calcium carbonate, and small amount of magnesium hydroxide, fluoride and sulfate.
Detailed explanation-4: -By volume, bone comprises of 36% inorganic, 36% organic and 28% water. The inorganic/mineral component comprises of calcium and phosphate in the form of needle-like or thin plates of hydroxyapatite crystals [Ca10(PO4)6(OH)2]. These are conjugated to a small proportion of magnesium carbonate, sodium and potassium ions.
