Bone mineral composition predominantly consists of hydroxyapatite, a crystalline structure made up of calcium phosphate. This mineral is essential for providing bone strength and rigidity. Additionally, bones contain smaller amounts of other minerals, including calcium carbonate, magnesium, and fluoride. These minerals work collectively to support the framework of the skeletal system, ensuring that bones can withstand stress and pressure while maintaining their integrity. Collagen, a structural protein, also plays a crucial role in providing elasticity and flexibility to bones, complementing the hard mineral components. This unique composition helps bones perform their functions effectively in protecting organs, supporting body weight, and facilitating movement.
