Mode of Action:
Calcium exists in bone primarily in form of hydroxyapatite. Hydroxyapatite comprises approximate 40% weight of bone. The skeleton has an obvious structural requirement of calcium. The skeleton also serves as a reservoir of calcium.
It is Hydroxyapatite is chemically similar to the mineral component of bones and hard tissues in mammals.
- The ability to integrate in bone structures and support bone in-growth, without breaking down or dissolving.
- Hydroxyapatite is a thermally unstable compound, decomposing at temperature from about 800-1200°C.
Metabolism:
Calcium is absorbed from small intestine. Further it undergoes various metabolic processes.
Role:
- Calcium plays an important role in building stronger, denser bones early in life and keeping bones strong and healthy later in life.
- Approximately 99 percent of the body's calcium is stored in the bones and teeth. The rest of the calcium in the body has other important uses, such as some exocytosis, especially neurotransmitter release, and muscle contraction. In the electrical conduction system of the heart, calcium replaces sodium as the mineral that depolarizes the cell, proliferating the action potential.
