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 hopenes, hopanols and hopanes, but also to extensively functionalized derivatives such as bacteriohopanepolyols (BHPs) … See more About 10% of sequenced bacterial genomes have a putative shc gene encoding a squalene-hopene cyclase and can presumably make hopanoids, which have been shown to play diverse roles in the See more Hopanoids have been estimated to be the most abundant natural products on Earth, remaining in the organic fraction of all sediments, … See more Squalene synthesis Since hopanoids are a C30 terpenoid, biosynthesis begins with isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAP), which are combined to form longer chain isoprenoids.

WebEach of Hopanoid molecule consists of four six-carbon rings and one five-carbon ring at one end. Hopanoid lipids connect their rings by sharing one carbon-carbon single bond between the two neighbouring ring structures and forms flat, hydrophobic, and stable chemical structures. This strengthen the bacterial cell wall and hence it is the ...
