Scans in the ‘near-UV’ range, i.e. 250–300 nm, give information about tertiary structure. WebMar 29, 2024 · In addition, the circular dichroism results show that the β-sheet content of U-LG, S-LG–LUT and U-LG–LUT increased, and the decrease in the H 0 value is significantly correlated with the increase in protein β-sheet content, a result that is consistent with the secondary structure change of protein .
