Calcitriol is a steroid hormone and active form of vitamin D. It regulates the level of calcium and phosphorus in the body. Calcitriol is used to treat hyperparathyroidism, metabolic bone disease in people with chronic kidney failure, calcium deficiency, and hypothyroidism. Vitamin D3, or cholecalciferol is produced in the skin keratinocytes when light energy is absorbed by 7-dehydrocholesterol (cholesterol derivative). Calcitriol is absorbed by the gut in presence of estrogen.
Vitamin D, is metabolized within the body to the hormonally active form 1,25-dihydroxycholecalciferol. In the liver, cholecalciferol is hydroxylated to 25-hydroxycholecalciferol by the enzyme 25-hydroxylase. In the kidneys, 25-hydroxycholecalciferol is acted upon by 1-alpha-hydroxylase, to form the biologically active form 1,25-dihydroxycholecalciferol (Calcitriol).
Rickets is a skin disease caused by low levels of phosphorus in children. It causes growth retardation, muscle weakness, skeletal deformities, hypocalcemia, tetany, and seizures. Low levels of vitamin D lead to lower phosphorus levels in children.
Right options are as follows:
Calcitrol regulates calcium uptake by the digestive system and both calcium and phosphorus metabolism in the cell.
Calcium and phosphorous are important to bone development and mineralization
When keratinocytes cells are exposed to sunlight, the ultraviolet (UV) rays assist them in producing vitamin D from a precursor molecule.
Only a small amount of UV radiation is needed.
Most milk today is fortified with vitamin D, which helps prevent rickets which is characterized by soft and deformed bones.
Vitamin D leaves the skin and enters the liver and kidneys where it is converted to a hormone called calcitriol.
Skin produces Vitamin D.
