FT-IR Analysis of pH and Xylitol Driven Conformational Changes of Ovalbumin–Amide VI Band Study
November 21st 2024This study uses Fourier transform infrared (FT-IR) spectroscopy to analyze how the globular protein ovalbumin's secondary structures transition under varying pH conditions in the presence of the cosolvent xylitol, highlighting the role of noncovalent interactions in these conformational changes.
