Solvent quality and solvent polarity in polypeptides
Physical Chemistry Chemical Physics, 2023 Synthetic polymers assume a compact/extended conformation in a poor/good solvent. Proteins, formed by both hydrophobic and polar moieties fold in water but not in apolar solvents. This difference can be rationalized and quantified by calculating the solvation free energy.
