Ontrol (red and blue lines) lignosulfonates have been really similar (Added file 1: Figure S4), and the exact same was observed within the 2D-NMR spectra (Extra file 1: Figure S5 cf, ad, respectively). The above final results indicate that the phenolic lignin moiety: (i) promoted lignosulfonate modification below steady-state circumstances; and (ii) was also accountable for the (smaller) modification of native lignin by the W164S variant.S zJim ez et al.

PC Biotin-PEG3-NHS ester Autophagy signals correspond to 13C1H correlations at the various positions of lignin nativeoxidizedsulfonated syringyl (red signals) and guaiacyl (green signals) units, sulfonatednonsulfonated side chains in O4 (blue signals), phenylcoumaran (cyan signals), and resinol (purple signals) substructures, and methoxyls (orange signal) (gray, unassigned signals). Very same volume of sample (40 mg ahead of enzymatic remedy) and DMSOd6 (0.75 mL) were applied for all of the spectra, which have been regular ized towards the identical intensity of your DMSO signal (not shown) for comparison.
