Cholecalciferol (Alt. Spelling: Colecalciferol), also known as vitamin D3 helps proper bone growth by aiding with the absorption of calcium and phosphorus in humans. It has the molecular formula C27H44O, and weighs 384.6 g/mol. Vitamin D3 is odorless, colorless, solid, water-insoluble, and has a melting point of 83 Degrees C. Vitamin D3 is synthesized in the skin of omnivores and herbivores by UV rays from the sun, which is why it is called the “sunshine vitamin”. Carnivorous animals get vitamin D3 from their prey.
Many studies have shown that a large percentage of the world's population is deficient in vitamin D. Another name for vitamin deficiency is hypovitaminosis, and symptoms for hypovitaminosis D3 in humans include bone weakness and decreased bone density, which causes osteoporosis. Hypovitaminosis-D3 also causes chronic diseases such as cancer, diabetes, cardiovascular diseases, and auto-immune disorders. Having enough vitamin D3 is necessary for your health.
