Notes:
main provitamin in skin that is converted by sunlight to cholecalciferol (vitamin d3). 7-Dehydrocholesterol is a zoosterol (a sterol produced by animals rather than plants). It is a provitamin-D. The presence of this compound in skin enables humans to manufacture vitamin D3 from ultra-violet rays in the sun light, via an intermediate isomer provitamin D3. It is also found in breast milk.
