Also known as hopanes, hopanoids
alt=|thumb|377x377px|Some representative hopanoids: A. Diploptene, also called 22(29)-hopene B. Diplopterol, also called hopan-22-ol, the hydrated cyclomer of diploptene C. Bacteriohopanetetrol (BHT), a common extended hopanoid D. Hopane, the diagenetic product of A and B that results from reducing conditions during deposition and persists in the rock record. The diagenetic product of C would be an extended C35 hopane.Hopanoids are a diverse subclass of triterpenoids with the same hydrocarbon skeleton as the compound hopane. This group of pentacyclic molecules therefore refers to simple hopene
