Vitamin D3. Computer model of a molecule of vitamin D3 (cholecalciferol). Atoms are represented as spheres and are colour-coded: carbon (yellow),hydrogen (white) and oxygen (pink). This is the form of vitamin D produced in the human body by the action of sunlight on skin. Vitamin D is fat- soluble and also found in foods such as oily fish,milk liver and egg yolk. Vitamin D is necessary for the absorption of calcium and phosphorous in the gut. Deficiencies in vitamin D lead to rickets (improper bone formation) in children,and osteomalacia (bone softening) and osteoporosis (brittle bone disease) in adults | |
