The answer to this question would be: vitamin D

The UV is needed by the skin to make previtamin D3. Previtamin D3 or cholecalciferol made from the skin will be changed in the liver into 25- hydroxyvitamin D3 and then sent to the kidney to be changed into 1,25- dihydroxyvitamin D3. The last change in the kidney will active the vitamin D. Vitamin D has a role in the calcium absorption which was will strengthen the bone tissue.

UV rays are released by the sun and required by the body to make pre-vitamin and synthesize the vitamin D in the body.

Further Explanation:

Vitamin D is a kind of vitamin that is activated in the presence of sunlight. Phytoplankton and zooplankton are present in the ocean and make vitamin D when they are exposed to the sunlight. The synthesis of vitamin D is started when exposed to ultraviolet lights. The precursor of vitamin D is 7-dehydrocholesterol, which is mainly a rigid and four-ringed structure. The precursor of vitamin D is present in the lipid structure of the plasma membrane. When the UV light is interacting with the pre-vitamin D structure, then the rings mainly open and become very less rigid. The main steps in the synthesis of vitamin D are:

• In the presence of UV radiation precursor of vitamin D is activated and synthesize cholecalciferol

• Cholecalciferol is changed into the calcidiol in the liver

• Then the calcidiol is changed into vitamin D in the kidney.

• Vitamin D mainly helps in absorption calcium and phosphorus. These minerals are essential for healthy bones.
