Is ergosterol

Ergosterol is a sterol compound found in the cell membranes of fungi and some protozoa, functioning similarly to cholesterol in animal cells. It plays a crucial role in maintaining membrane integrity and fluidity. Ergosterol is also significant in medicine, as it is a target for antifungal drugs, such as azoles, which inhibit its synthesis. Additionally, when exposed to ultraviolet light, ergosterol can be converted into vitamin D2.
