プレビタミンD3は、コレカルシフェロールビタミンD3)生成の中間体である。

紫外線、特に波長295~300nmのUVB光が皮膚の表皮層にある7-デヒドロコレステロールに作用することによって形成される。

The B ring of the steroid nucleus structure is broken open, making a secosteroid. This then undergoes spontaneous isomerization into cholecalciferol, the prohormone of the active form of vitamin D, calcitriol.

プレビタミンD3の合成は、日焼け止めによって効果的に阻害される。
