In liver, cholecalciferol is hydroxylated to 25-hydroxyvitamin D3 [25(OH)D3], which is the major circulating form of vitamin D. Production of 1, 25(OH)2D3 is effected by the enzyme 25(OH)D-1α-hydroxylase and is tightly regulated by serum phosphorus, parathyroid hormone (PTH) levels and a number of other factors 10.

Compared to UVC, UVB has a lower energy. Heat Exhaustion Dehydration with prolonged sun or heat exposure can cause heat exhaustion. The lighter a child's natural skin color, the less melanin it has to absorb UV rays and protect itself.
Vitamin D has an important role in regulating cell growth.
