The hormone’s on the wall

Molecular astrophysicist “Invader Xan” just posted a photo on Twitter showing a chemical structure painted on the wall at Schloss Ringberg. It looked like a steroid hormone to me and Invader, but were weren’t sure which. It didn’t take more than a minute or so for me to draw it on the emolecules site and do a quick search: 17-acetyl-10,13-dimethyl-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopent a[a]phenanthren-3-one, better known as progesterone or pregn-4-ene-3,20-dione a hormone involved in menstruation, pregnancy, embryogenesis in humans and other species.
