摘要：

Use of peptides and proteins in many different applications requires a more detailed structural characterization of these in different environments. Information on structural properties of peptides and proteins in various solvents are also given by Fourier transform infrared (FT-IR) spectroscopy. Here, we investigate the amide I, II, and Ill bands of peptides using both FT-IR spectra and their second derivatives. This paper reveals a large body of information obtained by FT-IR technique that can be used to understand the structure and stability of some peptides and proteins in different environments. Circular dichroism (CD) spectroscopy support data obtained within FT-IR experiments.
