Thermodynamic Parameters for Folding of Triple-Helical Collagen-Related Peptides

peptide Tma ΔH (kcal/mol)b –TΔS (kcal/mol)b ΔG (kcal/mol)b
(hypProGly)15 25 −29.9 20.5 −9.4
(mopProGly)15 47 −24.7 13.1 −11.6
(ProProGly)15 65 −32.8 19.0 −13.8
a

Values (±1 °C) were determined in triplicate by CD spectroscopy.

b

Values were estimated by DSC and reported here at 46 °C. The largest source of error (±5%) was in the determination of [peptide].
