Figure 8.
Thermal unfolding of pH-destabilized 30-mer 6 in 5 mM sodium citrate, 5 mM sodium phosphate buffer, pH 4.1, containing 0.1 M NaCl. CD spectra were taken at a concentration of 23 μM. Temperature from bottom to top at 203 nm: 5, 15, 25, 35, 55, and 75°C. (Inset) DSC scan at a peptoid concentration of 460 μM. Cp in kcal/mol⋅K, scan rate was 1°C/min. ΔHcal = 1.1 kcal/mol per residue.
