What is CAS 434-16-2 7-Dehydrocholesterol Powder? 
  

 

Product Name:	7-Dehydrocholesterol

MF:	C27H44O
MW:	384.64
EINECS:	207-100-5

7-Dehydrocholesterol is a natural active ingredient found in the skin.  In the epithelial cells of the intestinal wall, cholesterol is oxidised to 7-Dehydrocholesterol, which is then transported to the skin.  Exposure to UV radiation converts 7-Dehydrocholesterol into an activated form of the vitamin precursor (cholecalciferol).  The reaction mechanism is that the conjugated diene group of 7-Dehydrocholesterol absorbs UV radiation in the wavelength range of 250-310 nm, leading to the opening of the B-ring of the steroid nucleus and the formation of pro-vitamin D, which is then isomerised in a non-enzymatic reaction to form cholecalciferol, also known as vitamin D3.
