Error in Figures
In the original publication [1], there were mistakes in the α-L-Araf unit of Figures 2I, 3A,D and 6I as published. According to the Haworth projection rules for pentose aldofuranose, the D/L configuration is determined by the orientation of the C-4 substituent (up for D, down for L), and the α/β anomeric configuration is defined by the relative orientation of the anomeric C-1 hydroxyl group to the C-4 substituent (same orientation for β, opposite for α). The corrected Figure 2, Figure 3 and Figure 6 appear below.
