Answer 2

Vitamin D is produced in the body when exposed to sunlight. The precursor of vitamin D is present in the body in the form of cholesterol, 7- dehydrocholesterol. When body is exposed to sunlight, UV radiations are received by the skin. These radiations convert the precursor cholesterol into vitamin D3 in the skin. this vitamin is carried to the liver where it is converted into active form, the Vitamin D.
