vitamin d3 usage and synthesis
vitamin d vitamin d is steroid derivatives. it is the general term for the compounds that have similar structures and have the effect of normal skeletal growth and maintenance. at present, there are at least more than ten kinds of sterols that have vitamin d activity. but there are only two important matters, which are known as pro-vitamin d. one is ergosterol that exists in vegetable oil or yeast, which can generate vitamin d2 when irradiated by sunlight or ultraviolet radiation. it is also known as cholecalciferol or ergocalciferol. another is 7-dehydrochlesterol that exists in the skin. it will become vitamin d3 after irradiated by the light. it is also called cholecalciferol. d2 and d3 have similar structures. they are b ring derivatives of precursors of the sterol. the difference is that the side chain of vitamin d2 has a methyl group and one double bond.
vitamin d2 and d3 are all colorless crystals. the melting point of d2 and d3 respectively are 115~118℃ and 84~85℃. they are insoluble in water, and soluble in ethanol and other organic solvents. their solubility in vegetable oil are small. crystalline vitamin d should be stored in dark to light and oxygen at low temperature. vitamin d3 is more stable than d2. it is not easy to be oxidized. vitamin d has heat stability in the near neutral solution. it will be rapidly destroyed in the acidic solution, and the rate of destruction depends on strength and temperature of the acid. however, it is stable in alkaline solution. it can tolerate alkali treatment even under high temperature conditions.
in the industrial synthesis products, vitamin d3 is more. vitamin d3 is sensitive to light and can be damaged by minerals and oxidation. but vitamin d3 has good stability after esterification and coated by gelatin, sugar and starch. the activity of vitamin d3 is also represented by international units (iu). the amount of iu crystals vitamin d3 is 0.025μg. the active ingredient content of the industrial synthesis of vitamin d3 additive is more of 500,000 iu/g or 200 000 iu/g. for vitamin additives products, there are also additives that contain vitamin a and vitamin d3. the activity is usually 1g additive containing 500,000 iu of vitamin a and 100,000 iu of vitamin d3. the two has no antagonistic effect. and their production and use are very convenient. vitamin d can increase the absorption and metabolism of calcium and phosphorus, prevent swine rickets, and promote the development of teeth and bones. vitamin d dosage of pig feed is 125~200iu/kg. the amount for piglets is higher than growing pig. the amount of boar and growing pig are similar.
