Table 1.

Thermodynamic parameters for WKMe3 and WtbutylNle at 298 K (19)

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%.
