Which of the following is the chief mineral of bone?
Correct Answer: Hydroxyapatite
Description: The inorganic or mineral component is mainly crystalline hydroxyapatite--Ca10(PO4)6(OH)2--along with sodium, magnesium, carbonate, and fluoride; approximately 99% of the body's calcium is contained in bone. Hydroxyapatite confers on bone the strength and resilience required by its physiologic roles. Type I collagen is the major protein, comprising 90-95% of the organic material.
