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.
