Peak positions were calibrated with solvent residue peaks as internal standard. Electrospray mass spectrometry was performed on a PE-SCIEX API 3000 triple quadrupole mass spec- trometer. Infrared spectra were recorded as KBr plates on an Avatar 360 FTIR spectrometer. UV–visible spectra were recorded...
The Nio- CGLD's FTIR spectrum (Fig. 2B) shows two CGLD peak values at 2920.38 cm−1 and 1254.32 cm−1 and two noi- some peak levels at 1589.70 cm−1 and 1062.79 cm−1. The FTIR spectra of the CG-Nio-CGLD (Fig. 2B) indicate an increase at 3377....
IR spectra were obtained as KBr disks, as solids via a diffuse reflectance accessory using a KBr matrix, or between NaCl plates using a Perkin Elmer 1600 series FTIR. All reagents and solvents were general purpose grade, where necessary reactions requiring anhy- drous conditions were performed ...
Initial hydration steps in lipase studied by means of water sorption isotherms, FTIR spectroscopy and thermally stimulated depolarization currents The role of water in lipases, a class of proteins endowed with a large external hydrophobic surface, is not yet fully understood. To analyse the water-rel...
Figure 4.FTIR spectra of Maillard-derived CDs. 2.2. Radical Scavenging Ability Radical scavenging activity of CG-CDs was analyzed using DPPH assay (Figure 5). The result revealed that CG5and CG10exhibited high scavenging ability against a DPPH of 70% and 60%, respectively, at low concentration...
IR spectra were recorded at room temperature in transmission mode using a Bruker Vertex 70 FTIR spectrometer, which was continuously flushed with dried air to minimize water–vapor background, coupled to a Hyperion 3000 microscope equipped with (1) a usual nitrogen-cooled MCT-D316-025 (mercury ca...

Understanding and solving abnormal peak splitting in 3D HCCH-TOCSY and HCC(CO)NH-TOCSY The 3D HCCH-TOCSY and HCC(CO)NH-TOCSY experiments provide through bond connectivity and are used for side-chain chemical shift assignment by solution-state... Y Xia,T Yuwen,P Rossi - 《Journal of Biomolec...
The sample solution was dropped onto a KBr pellet to conduct the Fourier Transform Infra-Red (FTIR) measurement using IR Prestige-21 FTIR Spectrometer (Shimadzu, a spectra resolution of 1 cm−1). 1H NMR spectra was recorded by 500 MHz NMR Agilent DD2 Spectrometer (Agilent ...
1. . ATR-FTIR spectra of control and SCP mutant. Normalized Fourier transform-Infrared spectra from total cells of the SCP mutant and the control. The bands with a wave number between 900–1200 cm− 1 are attributed to carbohydrates, while the amide I and the amide II peaks (1700–1500...
