## Abstract The circular dichroism of Acβ(Ala)~__x__~βOMe and HβLysβ(Lys)~__x__~βOH with __x__ = 1, 2, 3, and 4 has been measured in aqueous solutions. The oligomers with __x__ = 4 show similar circular dichroism spectra in water when the lysyl amino groups are protonated, and they respond in simil

The interaction of methyl orange with poly(L-lysine) was studied kinetically by the stopped-flow technique with CD detection, as well as by static CD titration experiments. In the static experiments, the differences observed in the polymer-to-dye ratio dependences of the CD spectra and absorption sp
## Abstract The positive circular dichroism band observed near 228 nm with poly(Lβproline) responds in a similar fashion to HCl and CaCl~2~. The spectra in the HCl solutions are compatible with a simple binding equation and a p__K__ near β2 for the dissociation of a proton from a protonated peptide
## Abstract Pexiganan (GlyβIleβGlyβLysβPheβLeuβLysβLysβAlaβLysβLysβPheβGlyβLysβAlaβPheβValβLysβIleβLeuβLysβLys), a 22 amino acid peptide, is an analogue of the magainin family of antimicrobial peptides present in the skin of the African clawed frog. Conformational analysis of pexiganan was carried
