Vitamin D is a fat-soluble vitamin and is also regarded as a hormone precursor that acts on calcium and phosphorus metabolism. It is closely related to sunlight, so it is also called "sunshine vitamin". Vitamin D is a general term for a family of complexes with the same ring structure of A, B, C, and D, but different side chains. The structure of the A, B, C, and D rings is derived from the cyclopentahydrophenanthrene ring structure of steroids. There are at least 10 known types of vitamin D, but the most important are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol)
