The molecule is an amino trisaccharide that is alpha-L-fucosyl-(1->4)-N-acetyl-beta-D-glucosamine in which the hydroxy group at position 3 of the N-acetyl-beta-D-glucosamine moiety has been converted to the corresponding alpha-L-arabinopyranosyl derivative. It is an amino trisaccharide and a member of acetamides. It derives from an alpha-L-fucosyl-(1->4)-N-acetyl-beta-D-glucosamine and an alpha-L-arabinopyranose.
N-[(2R,3R,4R,5S,6R)-2-hydroxy-6-(hydroxymethyl)-5-[(2S,3S,4R,5S,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy-4-[(2S,3R,4S,5S)-3,4,5-trihydroxyoxan-2-yl]oxyoxan-3-yl]acetamide
