(+)-Vitamin D2

Description:
(+)-Vitamin D2, also known as ergocalciferol, is a fat-soluble vitamin that plays a crucial role in calcium and phosphorus metabolism in the body. It is synthesized by the ultraviolet irradiation of ergosterol, a compound found in yeast and fungi. This vitamin is essential for maintaining bone health and supporting immune function. Chemically, it is characterized by its steroid structure, which includes a secosteroid configuration due to the breaking of one of its rings. Ergocalciferol is typically found in dietary supplements and fortified foods, and it can also be produced endogenously when skin is exposed to sunlight. Its biological activity is similar to that of Vitamin D3, although it is less potent. In terms of solubility, it is soluble in organic solvents but not in water, which influences its absorption and metabolism in the body. Deficiency in Vitamin D2 can lead to various health issues, including rickets in children and osteomalacia in adults. Overall, (+)-Vitamin D2 is vital for overall health, particularly in maintaining skeletal integrity.
