The ATR-FTIR absorption bands of amide carbonyl vibration of DMPC:DMPG lipid alone and in the presence of TMD, FP and their complex. The higher-frequency band is assigned to the non-hydrogen bonded lipid owing to dehydration, while the lower-frequency band is assigned to hydrated hydrogen bonded lipid. It is seen that the percentage of dehydrated bands increases as the two peptides form a complex and FP has a higher dehydration level than TMD.
