Gln143 bears the most electronegative charge, and calculations suggest less covalent electrons for the Oε1–Cε1bond compared to that of Nε2–Cε1, with bond orders of 1.33 and 1.52, respectively (Supplementary Table1). The presence of an SSHB is supported as well since the deprotonated ...
The spectral processing was performed with ProNMR (Softpulse Software, Guelph, Ontario, Canada) using zero filling to 4 K datapoints, 1 Hz line broadening applied in the time domain, Fourier transformation, and zero-order phase and baseline correction. Areas under the peaks, including the AA re...
In the NMR spectra of 31 P of H- Ca5(PO4)3OH and Li-Ca5(PO4)3OH, there is only one single chemical shift peak, 3.353 ppm and 3.323 ppm, respectively. This indicates that P exists in the form of Q0, i.e., free PO43-, in H-Ca5(PO4)3OH and Li-Ca5(PO4)3OH. The ...
Students did not perform the NMR analyses themselves but had the opportunity to use 1H NMR data collected for their synthesized compounds to interpret the success of their syntheses. Table 2 provides a summary of various aspects of the online and in-person courses. Figure 2: Lab flow interphase...
Test-retest reliability measures for all the metabolites are given in the eTable in the Supplement. Other Metabolites At baseline, patients showed higher Glx levels in the associative striatum compared with controls (t40 = 2.03, P = .048). After 4 weeks of antipsychotic treatment, ...

After irradiation, an apparent narrow NMR line at 4.1 ppm (H3) as well as a smaller peak at 2.4 ppm appear. It is a clear evidence that the narrow line of H3 after irradiation arises from the implanted protons, superimposing the broad one of H0 before irradiation. It is seen from ...
In intact transhydrogenase, the N terminus of dIII is directly connected to dII through the polypeptide chain, but the segment that emerges from the membrane-spanning component is disordered in the X-ray structure (residues 837–858) and according to NMR data [37]. It comprises mostly small...
Thus, the dis- tribution of molecular weight for the polymers used here is not considered to cause the double peak. As seen in Figure 2, the aCH resonance did not show the double peak in the transition 432 Polymer J., Vol. 8, No. 5, 1976 NMR of Copoly(r-Bzl-Glu, r-Me-Glu) ...
