Phosphorus is one of the mineral elements, indeed a major mineral required by the body for its proper metabolism. The term metabolism used here is in a loose sense. Actually, phosphorus level in the body is checked alongside with that of calcium. This is done by the hormone secreted by the parathyroid gland, the parathyroid hormone (PTH). This hormone is supported by the prohormone, provitamin D3, which is actually produced by the direct rays of the UV light at about 298nm on a substrate know as 7-dehydrocholesterol found on the skin.
The regulation of phosphorus alongside with calcium in the body is important in bone formation and mineralisation as well as in teeth formation. The amount of these minerals in different parts of the body like the bone marrow and the plasma must be controlled effectively to avoid disease states.
