Sterane (cyclopentanoperhydrophenanthrenes) compounds are a class of tetracyclic compounds derived from steroids or sterols via diagenetic and catagenetic degradation and hydrogenation. Steranes have an androstane skeleton with a side chain at carbon C-17. The sterane structure constitutes the core of all sterols. Steranes are sometimes used as biomarkers for the presence of eukary… WebPeople named Cyclopentanoperhydro Phenanthrene Find your friends on Facebook Log in or sign up for Facebook to connect with friends, family and people you know.
