Cholecalciferol (English: Cholecalciferol, also known as vitamin D3 or cholecalciferol) is a kind of vitamin D. 7-dehydrocholesterol produced by dehydrogenation of cholesterol can form cholecalciferol by ultraviolet irradiation, so that is It is said that the vitamin D of cholecalciferol is 7-dehydrocholesterol. Cholecalciferol is hydrolyzed in the liver to form 25-hydroxycholecalciferol, which is then hydroxylated to 1,25-dihydroxycholecalciferol in the kidney. This substance is 50% more active than cholecalciferol. It has been proven to be a truly active form of vitamin D in the body. And 1,25-dihydroxycholecalciferol is a hormone secreted by the kidney, so in fact cholecalciferol is also a prohormone.
1. Dissolve 7-dehydrocholesterol in ethanol, open the ring with ultraviolet light, concentrate the reaction solution, freeze and filter, and condense the filtrate to dryness under reduced pressure to obtain a crude vitamin D3 solution. It is refined to obtain vitamin D3.
2. Extract 7-dehydrocholesterol that the human body cannot absorb from vegetable oil or yeast, dissolve it in chloroform or cyclohexane, and convert it into vitamin D3 by ultraviolet irradiation.
3. Dissolve 7-dehydrocholesterol in ethanol, open the ring with ultraviolet light, concentrate the reaction solution, freeze and filter, and condense the filtrate to dryness under reduced pressure to obtain crude vitamin D3, and then refine.
The vitamin D3 vitamin medicine mainly promotes the absorption and deposition of calcium and phosphorus in the intestine, and is used for treating rickets and osteomalacia.
