Testosterone Molecular Structure - Chemical Formula and 3D Configuration #1530888 (License: Personal Use)

This skeletal formula depicts testosterone, an androgenic steroid hormone with the IUPAC name (8R,9S,10R,13S,14S,17R)-17-hydroxy-10,13-dimethyl-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthren-3-one. The structure features a cyclopentanoperhydrophenanthrene core, a conjugated enone at ring A (C3=O, C4=C5), a C19 methyl group at C10, and a C13 methyl group, with stereochemical wedges indicating β-orientation of H at C8, C9, C10, C13, C14, and C17. The CH₂ at C10 indicates the exocyclic methylene (C19) typical of androgens.

Used in educational, medical, and scientific contexts-such as biology textbooks, endocrinology resources, pharmaceutical documentation, or research papers-to illustrate the chemical basis of male sex hormones and anabolic steroids. Matches user intent for understanding hormone structure, biosynthesis, or drug design.
