What Mineral Makes Compact Bone Strong and Hard?

Compact bone is a type of bone tissue that is strong and hard due to the presence of minerals. The main mineral responsible for making compact bone strong and hard is calcium phosphate, which is composed of calcium, phosphorus, and oxygen atoms. Calcium phosphate makes up about 70% of the total mineral content in compact bone.

How Does Calcium Phosphate Make Compact Bone Strong and Hard?

Calcium phosphate gives compact bone its strength and hardness by forming a crystalline structure known as hydroxyapatite. This crystalline structure binds together collagen fibers, which are the main structural component of compact bone. The combination of collagen fibers and hydroxyapatite gives compact bone its strength and hardness.

In addition to calcium phosphate, other minerals such as magnesium, sodium, potassium, zinc, iron, and manganese are also found in compact bone. These minerals help to regulate the body’s metabolism and provide essential nutrients for healthy bones.
