7-dehydrocholesterol

Examples of 7-dehydrocholesterol in the following topics:

• Metabolic Functions

  • One of the metabolic functions of the skin is the production of vitamin D3 when ultraviolet light reacts with 7-dehydrocholesterol.
  • Vitamin D3 is made in the skin when the 7-dehydrocholesterol reacts with ultraviolet light of UVB type at wavelengths between 280 and 315 nm, with peak synthesis occurring between 295 and 297 nm.
