Cholestane: Measurement & Research

Cholestane is a saturated tetracyclic steroid biosynthetically derived from triterpenoids. This 27-carbon biomarker is produced by diagenesis of cholesterol and is one of the most abundant biomarkers in the rock record. Presence of cholestane, its derivatives and related chemical compounds in environmental samples is commonly interpreted as an indicator…
