Structural Characterization and Antioxidative Activity of Low-Molecular-Weights Beta-1,3-Glucan from the Residue of Extracted Ganoderma lucidum Fruiting Bodies

Figure 3

The 1D NMR DOSY experiment of LMG. Based on the equation, the calculated molecular weight of LMG is 3979 Da. The signal of anomeric protons merged in the HOD at 4.8 ppm and the signal, at log𝐷=−9.0, is H₂O with molecular weight=18.
