Choline peak
WebOct 15, 2024 · The peak in the 1595 cm −1 band is associated with an aromatic ring tension that is strongly correlated with the aromatic C-O tension state. The peaks in the range of 1506–1510 cm −1 are characteristic peaks for the lignin components due to the C=O and COO-unsymmetrical tension vibrations in the aromatic rings in the lignin structure. WebDec 17, 2024 · As choline peak was observed both in benign and malignant bone lesions. Therefore the absence of choline peak is a significant factor to differentiate benign from malignant bone lesions. The negative predictive value in our study was 96.2%. All cases of GCT ( n = 7) showed choline peak (Fig. 7 a–d).
