Table 1.
Peptide | ΔH°, kcal/mol | ΔS°, cal/mol·K | ΔCp°, cal/mol·K |
---|---|---|---|
WK | −2.6 (0.1) | −6.2 (0.2) | −180 (30) |
WKMe3L | −0.1 (0.1) | +4.5 (0.3) | −240 (40) |
WtBuNle | +2.0 (0.4) | +12.9 (1.4) | −330 (50) |
Parameters were determined from the temperature dependence of the Gly chemical shift from 0°C to 80°C. Errors (in parentheses) are determined from the fit. The error for ΔCp° values is estimated at 15%.
