Vitamin D3, also known as cholecalciferol, is a type of vitamin D. The 7-dehydrocholesterol produced after cholesterol dehydrogenation can be irradiated by ultraviolet light to form cholecalciferol. Therefore, the vitamin D of cholecalciferol is originally 7-dehydrocholesterol.
Vitamin D3 is a fat-soluble vitamin known as the "sunshine vitamin" because most people can use ultraviolet rays and cholesterol in their skin to synthesize their own vitamin D when their skin is moderately exposed to sunlight. It is mainly synthesized by the human body itself. The skin of the human body contains a type of cholesterol that, after being exposed to sunlight, becomes vitamin D3.
1. Improve the absorption of calcium and phosphorus by the body, and achieve saturation of plasma calcium and phosphorus levels;
2. Promote growth and bone calcification, promote tooth health;
3. Increase phosphorus absorption through the intestinal wall and increase phosphorus reabsorption through the renal tubules;
4. Maintain normal levels of citrate in the blood;
5. Prevents amino acid loss through the kidneys.
Vitamin D3 naturally exists in liver, milk, and egg yolks. The industrial production method is to extract 7-dehydrocholesterol from vegetable oil or yeast, which cannot be absorbed by the human body, and then dissolve it in chloroform or cyclohexane. Then, it is converted into vitamin D3 by ultraviolet irradiation in a quartz glass flask.
