^aThe peptides (150 µM) were dissolved in 10 mM PBS (pH 7.4), 50% TFE, or 30 mM SDS.

^bThe mean residue molar ellipticities [θ]₂₂₂ (degree•cm²•dmol⁻¹) at wavelength 222 nm were measured at 25°C.

^cThe helical content (%) of a peptide relative to the molar ellipticity value of peptide T9F in 50% TFE.
