Structure and Nomenclature of Steroids

  • Alexander KasalEmail author


A formula of a steroid compound is easily recognized by its four-membered hydrocarbon core (Fig. 1.1a). My little grand daughter called it “a little cottage”, more advanced beginners may recall the term “cyclopentenoperhydrophenanthrene”. All the thousands of natural and synthetic steroids are derivatives of that core. Ring A is the cyclohexane ring on the left; it is attached to another six-membered ring B. The C ring follows, the D ring is a cyclopentane system.
