Vitamin D3 Structure
Uses 1. Vitamin D3 can maintain normal metabolism of calcium and phosphorus, promote the body's absorption of calcium and phosphorus. When it is lacked, children are easy to get rickets. Regulations in China provides it can be used to strengthening margarine. The dosage is 125~156μg/kg. The dosage in fortified dairy products is 63~125μg/kg. The dosage in strengthening infant food is 50~100μg/kg. And the dosage in strengthening milk and milk drink is 10~40μg/kg. The largest dosage in the strengthening solid drinks and ice cream is 10~20μg/kg.
2. Vitamin D3 can maintain normal metabolism of calcium and phosphorus and promote the body's absorption of calcium and phosphorus. The utilization of 1. vitamin D2 and D3 for pigs are the same, but the utilization of vitamin D2 for poultry is only 1/40-1/30 of vitamin D3. When lack of Vitamin D3, eggshell will become thin, the rate of laying will decrease, and rickets will appear. The amount can be 1000-1500IU/kg.
3. Vitamin D is a fat-soluble vitamin. There are a dozen compounds that are known to have the effect of vitamin D. Vitamin D2 and vitamin D3 have the important practical significance in no lines steroid derivative. D3 is given priority to with in the world, "International Standards" of vitamin D is pure crystalline D3. The main function of vitamin D are metabolism of calcium, phosphorus. It is difficult to promote the absorption of calcium and phosphorus and the calcification of bone. When the body is lack of vitamin D, the ability to absorb calcium and phosphorus will decrease, and the content of calcium and phosphorus in the blood will reduce. Then calcium and phosphorus cannot be deposited in bone tissue, even bone salt will dissolve and hinder the bone calcification. Children lack of vitamin D will get rickets. Adult lack of vitamin D will get osteomalacia. Japanese like to produce and use D2. In a variety of demand, the amount of pharmaceutical is 30%, feed additives is 65%, and food additives is 5%. According to the "food fortifier use of health standards (1993)" issued by Ministry of Health, D2 and D3, as nutritional supplements, can be used for liquid milk, margarine, dairy products and baby food.
4. Vitamin medicines. It mainly can promote intestinal absorption and deposition of calcium and phosphorus for the treatment of rickets and osteomalacia.
5. It is mainly used in food, health products and other related products.
Production method 1. 7-dehydrocholesterol is dissolved in ethanol, and then treated with ultraviolet light to open the ring. The reaction mixture is concentrated, frozen and filtered. The filtrate is concentrated under reduced pressure nitrogen to dryness to give a crude liquid vitamin D3. Then it is refined to get vitamin D3.
2. Vitamin D3 naturally exists in the liver, egg yolk and milk. The production method in the industry starts from vegetable oil or yeast to extract 7-dehydrocholesterol that is not absorbed by the human body. Then it is dissolved in chloroform or cyclohexane. And then it converts to vitamin D3 by the ultraviolet radiation in the quartz glass flask.

Chemical Properties Crystalline
Usage vitamin D3
Usage carnitine replenisher in peripheral arterial disease
Usage The vitamin that mediates intestinal calcium absorbtion, bone calcium metabolism and probably, muscle activity. Occurs in and is isolated from fish liver oils. Vitamin D acts through a receptor that i s a member of the ligand-dependent transcription factor superfamily. Modulates the proliferation and differentiation of both normal and cancer cells. Has antiproliferative and antimetastatic effects o n breast, colon, and prostate cancer cells. Activated vitamin D receptors in intestine and bone maintain calcium absorbance and homeostasis.
Usage selective phosphodiesterase-4 inhibitor (PDE-4 inhibitor) under investigation for treating respiratory diseases involving chronic inflammation such as asthma or COPD (smoker's lung)
