Ergosterol

Ergosterol is a sterol that is found predominantly in membranes of fungi. It is converted into vitamin D2 (Cay-11791) by ultraviolet light. Ergosterol and its biosynthetic pathway are significant targets for some fungicides.Formal Name: (3beta,22E)-ergosta-5,7,22-trien-3-ol. CAS Number: 57-87-4. Synonyms: Provitamin D2.
