Key Chemical Elements in Bone Composition: Calcium, Phosphorus, Magnesium & More

The major chemical elements in bones are:

- Calcium: Calcium makes up about 39% of the weight of bone. It is essential for the formation of hydroxyapatite, the mineral that gives bones their strength and rigidity.

- Phosphorus: Phosphorus makes up about 18.5% of the weight of bone. It is also essential for the formation of hydroxyapatite.

- Magnesium: Magnesium makes up about 1.5% of the weight of bone. It is important for bone strength and flexibility.

- Sodium: Sodium makes up about 0.5% of the weight of bone. It helps to regulate the balance of fluids in bones.

- Potassium: Potassium makes up about 0.4% of the weight of bone. It is important for bone growth and repair.

- Zinc: Zinc makes up about 0.3% of the weight of bone. It is important for bone mineralization and growth.

- Copper: Copper makes up about 0.01% of the weight of bone. It is important for bone formation and repair.

- Iron: Iron makes up about 0.005% of the weight of bone. It is important for bone growth and repair.

- Fluorine: Fluorine makes up about 0.001% of the weight of bone. It helps to protect bones against cavities.
