Description: Ergosterol is a sterol found in fungi, and named for ergot, the common name of members of the fungal genus Claviceps from which ergosterol was first isolated. Ergosterol does not occur in plant or animal cells; reports of its isolation from plants are generally ascribed to fungal contamination of the plant material from which steroids are being isolated. Ergosterol is a component of yeast and other fungal cell membranes, serving many of the same functions that cholesterol serves in animal cells. Ergosterol is provitamin form of vitamin D2; natural ultraviolet (UV) irradiation of ergosterol, isolated or in situ, results in vitamin D2 production that can contribute to satisfying human dietary vitamin D requirements.
