The definition of Cholecalciferol



 Vitamin D (Cholecalciferol) is a kind of fat-soluble vitamins, also be regarded as a kind of role in calcium, phosphorus metabolic hormones precursor, it has close relationship with the sun, so also called the "sunshine vitamin".
Vitamin D is a fat-soluble vitamin, also be regarded as a kind of role in calcium, phosphorus metabolic hormones precursor, it has close relationship with the sun, so also called the "sunshine vitamin". Vitamin D is group A, B, C, D ring structure is the same, but different side chains of the floorboard of the compounds, the structure of A, B, C, D ring ring from steroid e hydrogen on phenanthrene ring structure, known at least ten kinds of vitamin D, but the most important is the vitamin D2 (lysergic ossification alcohol) and vitamin D3 (bravery ergocalciferol).
Vitamin D2 is the ergosterol produced in ultraviolet irradiation plant, less exist in nature. Vitamin D3 is the most senior animal epidermis and the dermis contains some 7 - dehydrogenation cholesterol by ultraviolet irradiation (265 ~ 228 nm wavelength) transformation. Vitamin D3 is vitamin D in an active form of biological metabolic rate is highest. In the vitamin D mentioned in the article mainly refers to the vitamin D3. Vitamin D3 (bravery calciferol) is mainly by the body's own synthesis, the skin of the human body contains a cholesterol, after the sun, becomes the vitamin D3. So, if a child can fully accept the sun, its synthesis of vitamin D3, basically can satisfy. In addition, vitamin D3 also can come from animal food, such as liver, especially by the seafood kind fish liver extract cod liver oil. Vitamin D3 in addition to exist in a small animal food, mainly in the skin 7 - dehydrogenation cholesterol are formed after ultraviolet irradiation, and 7 - dehydrogenation bile alcohol is generated by cholesterol change, so people call it the sun vitamin.
