The reaction chemistry of these three, though not identical, is very similar (hence their positions in a single column of the Table). A biologist would pretty much give Kris_R's answer, but I'm looking for something more systematic and chemistry-based that would explain how a receptor could signal strongly on sulfur or selenium but not oxygen. | |
