The term Vitamin D collectively refers to a group of structurally similar chemicals and their metabolites, which includes alfacalcidol (1α-hydroxycholecalciferol), calcitriol (1,25- dihydroxycholecalciferol), cholecalciferol· (Vitamin D 3 ), dihydrotachysterol (DHT) and ergocalciferol (Vitamin D 2 ). These agents have antirachitic properties. In human beings there is no practical difference between the biologic activity of cholecalciferol (vitamin D 3 ) and ergocalciferol (vitamin D 2 ). One microgram (µg) of either compound is equivalent to 40 IU of vitamin D activity. Vitamin D is essential for the absorption and utilization of (calcium and phosphate and aids in the mobilization of bone calcium and maintenance of serum calcium concentrations. In humans, cholecalciferol (vitamin D 3 ) is synthesized in the skin, from7-dehydrocholesterol, on exposure to ultraviolet radiation. Cholecalciferol is also present in fish, liver oils, Ergocalciferol (vitamin D 2 ) is produced by ultraviolet irradiation of provitamin D sterol (ergosterol). Ergosterol is not synthesized in humans but is consumed in the diet from yeasts and plants. Cholecalciferol and ergocalciferol are hydroxylated in the liver by the enzyme vitamin D-25- hydroxylase to form 25-hydroxycholecalciferol (calcifediol) and 25-hydroxyergocalciferol respective اقرأ الوثيقة كاملة
