Usage And Synthesis
Overview

Sterols are essential structural and regulatory components of eukaryotic cell membranes. Mammals, plants and fungi produce similar sterols, which differ in the number and location of double bonds and methyl side chains. Ergosterol (ergosta-5, 7, 22-trien-3β-ol) 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 is the end product of the sterol biosynthetic pathway and is the major sterol in yeasts. Like cholesterol in mammalian cells, it is responsible for membrane fluidity and permeability[6]. Ergosterol is a very important component of yeast and other fungal cell membranes, playing many important roles as that cholesterol plays in animal cells.[1] Its specificity in higher fungi is thought to be related to the climatic instabilities (highly varying humidity and moisture conditions) encountered by these organisms in their typical ecological niches (plant and animal surfaces, soil). Thus, despite the added energy requirements of ergosterol synthesis (if compared to cholesterol), ergosterol is thought to have evolved as a nearly ubiquitous, evolutionarily advantageous fungal alternative to cholesterol.
