WebNov 1, 1993 · The secondary structure was characterized with Fourier-transform infrared spectroscopy (FTIR) and circular dichroism (CD), the surface hydrophobicity and charge with fluorescence-spectroscopy and ζ-potential, and the quaternary structure with membrane-osmometry, analytical ultracentrifugation (AUC) and mass spectrometry (MS). Webinfrared (FTIR) spectroscopy. FTIR spectroscopy is suitable to determine the relative amount of different secondary structure of proteins. This information can be obtained from the amide band I of protein in the IR spectrum, ranging from 1600 cm-1 to 1700 cm-1. Mathematical procedures such as band curve-fitting
WebThe β-sheet secondary structure of crystalline lens proteins has been linked to the amyloid formation. Amyloid β-sheets have a range from 1611 to 1630 cm −1 , whereas native β-sheet proteins produce amide I′ peak clustering between 1630 and 1643 cm −1 [ 28 ], which has been connected to the UV irradiation as a sign of degradation of ...
