Proposed hydrogen bond network for LSTc and LSTa rmsdexp min conformers. The hydrogen bond network at the nonreducing end of each glycan is strongly affected by the different linkage between Neu5Ac and Gal1 [α(2→3) for LSTa and α(2→6) for LSTc]. The acceptor and donor atoms lie within 2.6 Å of each other, and the X–H···Y (X is the donor and Y the acceptor) angle was greater than 110°, tending toward 180°. Predicted hydrogen bonds for both LSTa and LSTc appear in Table 6 of the Supporting Information.
