    Infobox references

    Cholestane is a saturated 27-carbon tetracyclic triterpene. Cholestane, along with ergostane and stigmastane are used as biomarkers for early eukaryotic life[2]. High abundance of cholestane relative to the others has been interpreted as the presence of rhodophytes[3].

    Derivatives of cholestane

    Derivatives are classified in two families:

    Some steroids, such as cholesterol, are both a sterol and a cholestene.
