7-Dehydrocholesterol is a zoosterol that serves as a precursor to cholesterol in the serum and acts as a provitamin-D3 in the skin. Upon exposure to ultraviolet UV-B rays from sunlight, it is photochemically converted into vitamin D3 (cholecalciferol) via previtamin D3, enabling the body to manufacture this essential nutrient.
