1. ergosterolnoun

   The steroid precursor of vitamin D2. It is found in cell membranes of fungi, and is their functional equivalent of cholesterol. It is also found in the membranes of some protists.

1. Ergosterol

   Ergosterol (ergosta-5,7,22-trien-3β-ol) is a sterol found in cell membranes of fungi and protozoa, serving many of the same functions that cholesterol serves in animal cells. Because many fungi and protozoa cannot survive without ergosterol, the enzymes that synthesize it have become important targets for drug discovery. In human nutrition, ergosterol is a provitamin form of vitamin D2; exposure to ultraviolet (UV) light causes a chemical reaction that produces vitamin D2.

1. ergosterol

   Ergosterol is a sterol found in cell membranes of fungi and protozoa, serving many of the same functions that cholesterol serves in animal cells. It is used in the biosynthesis of vitamin D2 and is a target of antifungal drugs. Ergosterol is a key component in the cell membranes of fungi and yeast, contributing to their fluidity and permeability.

1. Ergosterol

   Ergosterol is a sterol found in fungi, and named for ergot, a common name for the members of the fungal genus Claviceps from which ergosterol was first isolated. Ergosterol does not occur in plant or animal cells. It is a component of yeast and fungal cell membranes, serving the same function cholesterol serves in animal cells. Ergosterol is occasionally reported analytically to occur in grasses such as rye and alfalfa, and in plant flowers such as hops. However, such detection is usually assumed to be detection of fungal growth upon the plant, as fungi form an integral part of the grass decay system. This ergosterol assay technique may thus be used to assay grass, grain, and feed systems for fungal content. Since ergosterol is the provitamin of vitamin D2, the ultraviolet radiation of fungus-bearing grass materials can result in vitamin D2 production, but this is production of a form of vitamin D from fungus ergosterol and is not true vitamin D production by the plant itself from UV light, a process that cannot happen.

1. Ergosterol

   A steroid of interest both because its biosynthesis in FUNGI is a target of ANTIFUNGAL AGENTS, notably AZOLES, and because when it is present in SKIN of animals, ULTRAVIOLET RAYS break a bond to result in ERGOCALCIFEROL.
