a CD spectra of peptide variant coacervates. b FTIR spectra of GY23 peptide variant coacervates. c, d Deconvolution of the Amide I peak of GY23-9F/A (c) and GY23 (d) coacervates used to semi-quantitatively evaluate the relative ratios of secondary structures. All peptides formed coacervates at the test conditions.
