The intensities of the 1H-peaks properly indicate the proportion of these protons within a molecule, and therefore they are extremely useful to estimate the atoms and the percentage of each enantiomeric form (percentages in Figure 1). Actually, just after mass spectrometry (MS) techniques, ...
Full size image Subsequently, the 1H NMR spectra of the HA-MAL and its cysteine conjugation product (HA-CYS) were analyzed. In addition to the peaks corresponding to the HA-DVS (explained earlier), the NMR spectrum of HA-MAL (Fig. 3B) manifests the appearance of 1H peaks associated with...
Full size image However, almost all residues had chemical shift changes that were linear with concentration and could be fitted to give mL, for all three osmolytes. The results are shown in Fig. 8 (summarized in the form of histograms), which also compares the distributions to those seen for...
I have set up your presentation as a full podcast episode and as a video recording, without the podcast. It totally works! Yay. Via the podcast your presentation begins around 13:02 minutes into this week’s episode. I learned so much about a area of study I didn’t even knew existed...

Multiplet test The multiplet position and multiplicity of the peaks in the spectrum are compared to those determined from a standard material. If the two match, then the sample passes the peaks comparison test. The peak positions and multiplicity are shown in the boxes on the spectrum. Peak A...
