Description

7-Dehydrocholesterol (7-DHC), also known as provitamin D3 or 5,7-cholestadien-3-b-ol, belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 7-dehydrocholesterol is also classified as a sterol. 7-Dehydrocholesterol is known as a zoosterol, meaning that it is a sterol isolated from animals (to distinguish those sterols isolated from plants which are called phytosterols). 7-DHC functions in the serum as a cholesterol precursor and is photochemically converted to vitamin D3 in the skin. Therefore 7-DHC functions as provitamin-D3. The presence of 7-DHC in human skin enables humans and other mammals to manufacture vitamin D3 (cholecalciferol) from ultraviolet rays in the sun light, via an intermediate isomer pre-vitamin D3. 7-DHC absorbs UV light most effectively at wavelengths between 290 and 320 nm and, thus, the production of vitamin D3 will occur primarily at those wavelengths (PMID: 9625080 ). The two most important factors that govern the generation of pre-vitamin D3 are the quantity (intensity) and quality (appropriate wavelength) of the UVB irradiation reaching the 7-dehydrocholesterol deep in the stratum basale and stratum spinosum (PMID: 9625080 ). 7-DHC is also found in the milk of several mammalian species, including cows (PMID: 10999630 ; PMID: 225459 ). It was discovered by Nobel-laureate organic chemist Adolf Windaus. 7-DHC can be produced by animals and plants via different pathways (PMID: 23717318 ). It is not produced by fungi in significant amounts. 7-DHC is made by some algae and can also be produced by some bacteria.
