<title>Fourier deconvolution of the amide I FTIR band of insulin-polyamino acid complexes as related to conformation</title>

Fourier deconvolution has been employed to enhance the resolution of the amide I FTIR band of different insulin polyamino acid complexes and mixtures. The broad band was resolved into several components. The overall shape of the amide I band of complexes and mixtures was found to be nearly Lorentzian. Therefore a Lorentzian function was used for the deconvolution. The resolved band components were assigned to specific protein conformations.
