D Cholecalciferol Vitamin D3

 

D cholecalciferol vitamin D3 is a fat-soluble vitamin and is also regarded as a hormone precursor that acts on calcium and phosphorus metabolism. It is closely related to sunlight, so it is also called "sunshine vitamin".

 

Vitamin D is a general term for a family of complexes with the same A, B, C, and D ring structures but different side chains. There are at least 10 known types of vitamin D, but the most important are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).

 

Vitamin D3, also known as cholecalciferol, is a kind of vitamin D. The 7-dehydrocholesterol generated after dehydrogenation of cholesterol can form cholecalciferol after being irradiated by ultraviolet light, so that means the original vitamin D of cholecalciferol is 7 -Dehydrocholesterol.
