Heat maps of percent yields (applicable to aqueous environments at thermodynamic equilibrium spanning 0°C–100°C) relative to the starting limiting reagent, for (A) nucleobases, (B) ribose, and (C) C₂–C₁₂ fatty acids in our fiducial models. Columns correspond to varying NH₃ concentrations (relative to total water content), and rows list the individual molecules in each class. Cell shading follows a common viridis color scale, ranging from 0% (purple) to >70% (yellow) yield.
