Vitamin D research, conceptual image. Vitamin D (molecular structure shown on cover of book) refers to a group of vitamins. The ones most important in the human diet are vitamins D2 (ergocalciferol) and D3 (cholecalciferol). The molecular structure shown here is for vitamin D2 (ergocalciferol). Vitamin D plays a key role in calcium metabolism. Deficiencies in vitamin D in children can cause a condition known as rickets. | |
