Detailed explanation-1: -Among micronutrients, calcium (Ca) and inorganic (i) phosphate (P) are the two main constituents of hydroxyapatite, the bone mineral that strengthens the mechanical resistance of the organic matrix. Bone contains about 99% and 80% of the body’s entire supply of Ca and P, respectively.

Detailed explanation-2: -The main function of phosphorus is in the formation of bones and teeth. It plays an important role in how the body uses carbohydrates and fats. It is also needed for the body to make protein for the growth, maintenance, and repair of cells and tissues.

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 skeleton serves two major functions at the same time: A structural function – Strong bones support and protect our body and allow us to move about on dry land. A reservoir function – Bones contain large amounts of calcium and phosphorus and thus provide a reserve supply for these minerals.

Detailed explanation-5: -The release of calcium and phosphorus ions regulates the activation of osteoblasts and osteoclasts to facilitate bone regeneration. The control of surface properties and porosity of calcium phosphate affects cell/protein adhesion and growth and regulates bone mineral formation.
