(a)
Interpretation: A skeletal structure of the anabolic steroid
Concept introduction: Steroids, a group of tetracyclic lipids composed of one five-membered ring and three six-membered rings. These rings are lettered by A, B, C, and D. Most of the steroids contain two angular methyl groups. These methyl groups are numbered as
(b)
Interpretation: The addition of all wedges and dashed wedges for all stereogenic centers to steroid
