Reason: strain 56.1 kcal/mol
strain ΔE 56.1 kcal/mol 3 protein-contact clashes 3 intramolecular clashes 100% of hydrophobic surface is solvent-exposed (16/16 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
