- The precursor molecule is carried by the blood to the liver where it is enzymatically converted.
- The enzymatically converted molecule is carried by the blood to the kidneys where it is converted again to the active form of vitamin D.
- Vitamin D stimulates the small intestine to absorb calcium and phosphate for many body functions.
