Description
7-Dehydrocholesterol is a zoosterol that functions in the serum as a cholesterol precursor, and is converted to vitamin D3 in the skin, therefore functioning as provitamin-D3. The presence of this compound in human skin enables humans to manufacturevitamin D3 from ultraviolet rays in the sun light, via an intermediate isomer pre-vitamin D3. It is also found in the milk of several mammalian species.[1] In insects it is a precursor for the hormone ecdysone, required for reaching adulthood.[2] It was discovered by Nobel-laureate organic chemist Adolf Windaus.
