Ergosterol (ergosta-5,7,22-trien-3Î²-ol) is a sterol found in cell membranes of fungi and protozoa, serving many of the same functions that cholesterol serves in animal cells.ecause ergosterol is present in cell membranes of fungi, yet absent in those of animals, it is a useful target for antifungal drugs.
