Table 1. Summary of measured binding enthalpy values for chartreusin at different temperatures and calculated heat capacity change (ΔCp).
ΔHb(kcal/mol)a | ΔCp (cal/mol K)b | ||||
---|---|---|---|---|---|
20°C | 25°C | 30°C | 35°C | ||
Chartreusin | –7.1 ± 0.2 | –9.8 ± 0.7 | –11.4 ± 0.5 | –13.0 ± 0.3 | –391 ± 37 |
aValues are the mean ± SD of three independent titrations at each temperature, with 15–25 chartreusin injections per experiment.
bHeat capacity change calculated from the slope δ(ΔH)/δT obtained by linear least squares fit (r = 0.991).
