Vitamin D2, chemically known as Ergocalciferol, is a ring-opening steroid formed by the breaking of chemical bonds of steroids in response to photochemical action, in particular by ultraviolet light and ergosterols. Ergocalciferol can also be used as a dietary supplement to supplement vitamin D, as can ergocalciferol and cholecalciferol (vitamin D3), which is produced by skin exposure to ULTRAVIOLET light.
