Detailed explanation-1: -Bone is made mostly of collagen, a protein that is woven into a flexible framework. Bone also contains calcium phosphate and calcium carbonate, minerals that add strength and harden the framework.

Detailed explanation-2: -These observations suggest that the synthesis of bone mineral involves hydrolysis of an initial acidic calcium phosphate precipitate to octacalcium phosphate, which is then converted to octacalcium phosphate carbonate (OCPC) by virtue of the replacement of PO4 identical to (HPO4=) by CO3=.

Detailed explanation-3: -Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it’s needed by other parts of the body.

Detailed explanation-4: -The mineral component of bone and other biological calcifications is primarily a carbonate substituted calcium apatite.

Detailed explanation-5: -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. Bone is a dynamic tissue that is constantly undergoing osteoclastic bone resorption and osteoblastic bone formation.
