Figure 4.

NMR spectra (600 MHz, D₂O, 300 K) for the minor component from the purified peak 6. A. Key region of the HSQC experiment. The minor product signals are marked with a red dot and show the existence of [α‐Glc‐(1→2)‐β‐Fru] and [α‐Glc‐(1→x)‐Fru/Glc] type residues for G1 and G2. B. Superimposition of partial HSQC (red), HMBC (blue) and HSQC‐TOCSY (black) spectra, for the ¹³C region of 80 ppm, demonstrating the G2‐G1 connectivity in a non‐ambiguous manner. C. The key NOE that evidences the spatial proximity of the G1‐H1/F‐H1 pair.
