the liver and the kidney
The kidneys convert vitamin D to its active form, which is known as calcitriol. This active form of vitamin D plays a key role in regulating calcium levels in the body, promoting bone health and supporting other important bodily functions.
Calcitriol
Vitamin D is the important vitamin that is formed in the skin when it is exposed to sunlight. UVB rays from the sun convert a cholesterol derivative in the skin into vitamin D3, which is then converted into its active form in the liver and kidneys.
No, the liver does not synthesize vitamin D. The liver's role in vitamin D metabolism is to hydroxylate vitamin D to form calcidiol (25-hydroxyvitamin D3), which is then further metabolized in the kidneys to its active form, calcitriol.
The kidneys play a crucial role in the metabolism of vitamin D. They convert inactive vitamin D, obtained from food or sunlight, into its active form, calcitriol (1,25-dihydroxyvitamin D). This active form is essential for calcium and phosphate regulation in the body, promoting their absorption in the intestines and maintaining bone health. Additionally, the kidneys help regulate the levels of vitamin D in the blood to ensure optimal physiological function.

Calcitriol
The active form of vitamin D is called calcitriol. It is produced in the kidneys from its precursor, calcidiol, which is formed in the liver. Calcitriol plays a crucial role in regulating calcium and phosphorus levels in the body.
the active form of Vitamin D in the form of 1,25-dihydrocholecaciferol is released from the kidney.written by robal lacoul, hope it would provide some help
The answer is vitamin D. In presence of ultraviolet rays cholesterol is converted to vitamin D in the skin. One hydrogen atom is attached to it in liver and second in kidney to form active form of vitamin D.
The precursor to vitamin D is a prohormone called 7-dehydrocholesterol, which is present in the skin. When exposed to UV rays from sunlight, this precursor is converted into vitamin D3, which then undergoes further processing in the liver and kidneys to become the active form of vitamin D.
To produce vitamin D in a usable form, the skin, liver, and kidneys must work together. When the skin is exposed to sunlight, it synthesizes vitamin D3. This precursor then travels to the liver, where it is converted to calcidiol, and subsequently to the kidneys, which transform it into calcitriol, the active form of vitamin D that the body can utilize.
