摘要

The secondary structures of Ovalbumin at different pH values have been studied by Fourier transform infrared spectroscopy (FT-IR). Changes in the amide bands in FT-IR spectra of proteins are generally attributed to alterations in protein second structure. FT-IR spectroscopy is routinely used to classify the status or alteration of protein according to secondary structure. In this study, the spectra of ovalbumin at different pH values were analyzed. The second derivative analysis of FT-IR spectra permits direct quantitative analysis of the secondary structural components of proteins by curve fitting method.
