Vitamin D3:
1 Physiological function. Improve the body's absorption of calcium and phosphorus, so that the plasma calcium and phosphorus levels can be saturated.
2. Promote growth and bone calcification, and promote dental health;
3. Increase the absorption of phosphorus through the intestinal wall and increase the reabsorption of phosphorus through the renal tubules;
4. Maintain the normal level of citrate in the blood;
5. Prevent the loss of amino acids through the kidneys.
Application:
1. Vitamin medicine, which mainly promotes the absorption and deposition of calcium and phosphorus in the intestinal tract, and is used for the treatment of rickets and osteomalacia.
2. Vitamin D3 can maintain the normal metabolism of calcium and phosphorus and promote the absorption of calcium and phosphorus. Children are prone to rickets when they are deficient in rickets.

solubility |
Practically insoluble in water, freely soluble in ethanol (96 per cent), soluble in trimethylpentane and in fatty oils. It is sensitive to air, heat and light. Solutions in solvents without an antioxidant are unstable and are to be used immediately. A reversible isomerisation to pre-cholecalciferol takes place in solution, depending on temperature and time. The activity is due to both compounds. |
