Explanation:
Detailed explanation-1: -Calcium is the major component of the bone, where it is present at more than 99% as calcium-phosphate complexes, and provides the skeleton strength and structure, making the bone a metabolic reservoir to maintain the intra-and extra-cellular calcium pool.
Detailed explanation-2: -Bone composition and structure The major minerals found in bone are calcium and phosphorus in the form of an insoluble salt called hydroxyapatite [chemical formula: (Ca)10(PO4)6(OH)2]. Hydroxyapatite crystals lie adjacent and bound to the organic protein matrix.
Detailed explanation-3: -In bone, calcium exists primarily in the form of hydroxyapatite (Ca10 (PO4)6 (OH)2), and bone mineral is almost 40 percent of the weight of bone.
