Active vitamin D works by entering cells and attaching to a protein called the vitamin D receptor, located in the nucleus of cells, where the genetic material is located. This combination of calcitriol and its receptor stimulates the cell to make proteins that regulate the way the body works.
Vitamin D: An Overview. Vitamin D is a fat-soluble vitamin that is metabolized by the body by either sun (ultraviolet light) exposure or dietary intake. There are 2 molecules that make up vitamin D: ergocalciferol (D2) and cholecalciferol (D3). Ultraviolet B (UVB) radiation is absorbed by the skin and converts 7-dehydtocholesterol to vitamin D3. Vitamin D3 then goes into the capillary bed, where it binds to vitamin D binding protein (DBP).
