Cholecalciferol: Properties and Determination
2016Cholecalciferol (vitamin D) is the common form of vitamin D synthesized in animals, and the equivalent form in plants is ergocalciferol (vitamin D). Cholecalciferol is produced from provitamin D in human skin, on exposure to ultraviolet (UV) light. Due to avoidance of sunlight because of skin cancer concerns, vitamin D deficiency has become common in ...

The predominant source of vitamin D is the synthesis of cholecalciferol in the skin by the action of sunlight; however, due to the relative lack of sunlight, the intake of vitamin D from food is emphasized during winter, especially in the northern countries. Only a few foods (fish, eggs, wild mushrooms, meat, and milk) are natural sources of vitamin D.

Cholecalciferol (vitamin D) deficiency rickets remains an occasional problem in poultry. Diagnosis currently relies on analysis of feed and histopathological examination of bone. These experiments were designed to provide data that might allow diagnosis of cholecalciferol deficiency on the basis of plasma concentrations of 25-hydroxycholecalciferol, a ...
