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.
