Ergostane Explained

Ergostane is a tetracyclic triterpene, also known as 24S-methylcholestane. The compound itself has no known uses; however various functionalized analogues are produced by plants and animals. The most important of these are the heavily derivatised withanolides.[1] [2] However simpler forms do exist, such as the sterane campestane (24R-methylcholestane). Along with cholestane and stigmastane, this sterane is used as a biomarker for early eukaryotes.[3]
