![Biopolymer Solvent scoring. (A) Relationship between the fraction of the biopolymer compatible range and the liquid range of solvents and the average fractional efficiency for conversion of folding free energy to sequence information, for 54 solvents at 1 atm. Large black circle: water. Green circles: hydrocarbons. Magenta circles: small substances from C, H, O, N and S. Grey circles: other solvents in Table 1. Black line: range for water calculated from the uncertainty in the dynamic transition temperature presented in Figure 3 (values range from 180 to 230K). The grey lines indicate constant values of the BSscore (Equation [9]). (B) Ranking of the solvents according to the BSscore. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2023/10/solvent.png?resize=1200%2C720&ssl=1)
