  Abstract:  The average secondary structure content of proteins is often evaluated by FTIR spectroscopy. This study is focused on discussing the assessment of the secondary structure of lyophilized bovine serum albumin, fibrinogen and collagen proteins using amide I FTIR band analysis. The comparison of the obtained results with other data reported in the literature warns on the limited reliability of the quantitative information about protein secondary structure extracted from the analysis of the infrared spectra.

Keywords: FTIR, protein secondary structure
