Figure 1: Secondary structure patterns for antimicrobial peptides. Circular Dichroism (CD) experiments were carried-out to analyse secondary profiles present in selected cationic antimicrobial peptides. Resulting patterns are expressed as mean residue ellipticity (θ), the units being degrees∙cm2∙dmol-1 according to the (θ) = θλ/(100lcn) function where θλ is the measured ellipticity, l the optical path length, c the peptide concentration, and n is the number of amino acid residues in the sequence.
