Structural Information
- Structure Type: Fat-soluble vitamin, belonging to steroid derivatives.
- Structural Features: Possesses a seco-steroid skeleton with three conjugated double bonds. It has multiple chiral carbon atoms and strong lipophilicity, presenting unique physiological activity.
Physical & Chemical Properties
- Appearance: White crystalline powder
- Odor: Odorless
- Melting Point: 84 - 88 °C
- Specific Rotation: +105° ~ +112° (c=2, ethanol)
- Solubility: Soluble in ethanol, methanol, chloroform, ether and vegetable oil; practically insoluble in water
- Stability: Sensitive to light, heat and air. Easy to be oxidized and decomposed under long-term exposure to strong light, high temperature or oxygen. Keep sealed and protected from light strictly.
Synthesis & Applications
Synthesis Method
Industrial production is mainly obtained by ultraviolet irradiation of 7-dehydrocholesterol. After photochemical reaction, purification, crystallization and refining processes, high-purity vitamin D3 finished product is prepared. It can also be extracted from animal liver, fish liver oil and other natural sources.
Main Applications
- Pharmaceutical industry: Essential raw material for vitamin preparations, used for preventing and treating rickets, osteomalacia and osteoporosis.
- Health care products: Common additive in nutritional supplements, functioning to promote calcium and phosphorus absorption, maintain bone health and regulate immune function.
- Food industry: Applied as nutritional fortifier in dairy products, beverages, infant food and other foods.
- Feed industry: Widely added into animal feed to improve livestock and poultry growth and bone development.
Safety & Storage Instructions
- Hazard Classification: Low toxicity, excessive intake may cause metabolic disorders
