Table 22. Steroids
Details of the very specific steroid nomenclature must be taken from the original rule
codex (Pure Appl. Chern. 1989,61, 1783; see also I.c. 9 on page 5). Here only the fundamental compound types and the most elementary rules can be considered.

The following scheme displays the (exceptional) numbering conventions that hold also
for the fully unsaturated (mancude) basic skeleton, namely, 15H-cyclopenta[a]phenanthrene.
