^aδ_H in ppm.

^bData for the linkage of α-mannose residues were described previously by Paramonov et al. (30).

^cData for the linkage of N/O-linked 3-OH fatty acids were described previously by Que-Gewirth et al. (32).

^dThe position of this methylene group refers to an O-acyloxy substituent at position 3 in some of the O/N-linked fatty acids.
