Analysis of Protein Secondary Structure Using FTIR

Introduction

Techniques such as X-ray diffraction and NMR are often used for the structural analysis of proteins. Infrared spectrometry is also used for the analysis of items related to the secondary structure, such as the α helix and β sheet. Infrared spectrometry allows simple measurement regardless of the state of the sample (e.g., solid or liquid, crystalline or amorphous) and so it is used as a supplement to the above techniques. Information about the secondary structure of proteins that have infrared spectra is presented here.
