Peptides exhibit an α-helical secondary structure. a Circular dichroism spectra of peptides aqap5, AQAp5 (d) and AQAp5 adopt a helical secondary structure in the presence of low molecular weight heparin as evidenced by the change in mean residue ellipticity at 222 nm. b The heparin-mediated change in ellipticity at 222 nm yielded midpoints of 0.33, 0.15, and 0.19 mg for peptides aqap5, AQAp5 (d) and AQAp5, respectively
