The molecule is a glycosyl alditol derivative that is N-acetyl-D-galactosaminitol in which the hydroxy group at position 3 has been converted into the corresponding 2-acetamido-2-deoxy-alpha-D-galactopyranosyl derivative. It derives from a N-acetyl-D-galactosaminitol and a N-acetyl-alpha-D-galactosamine.
N-[(2S,3R,4R,5R,6R)-2-[(2S,3R,4S,5R)-2-acetamido-1,4,5,6-tetrahydroxyhexan-3-yl]oxy-4,5-dihydroxy-6-(hydroxymethyl)oxan-3-yl]acetamide
