Question

Quizplus · Accepted Answer

The skin is able to convert modified epidermal cholesterol to a vitamin D precursor important to calcium metabolism. This vitamin D precursor is then transported to the liver and kidneys where it is modified to the active form of vitamin D, which plays a crucial role in calcium homeostasis.
