n-acetyl-beta-d-galactosaminyl-(1->4)-n-acetyl-d-glucosaminyl group
An <em>N</em>-acetyl-<small>D</small>-glucosaminyl group having an <em>N</em>-acetyl-β-<small>D</small>-galactosaminyl residue attached at the 4-position; obtained formally by removal of the hydroxy function from the hemiacetal function of <em>N</em>-acetyl-β-<small>D</small>-galactosaminyl-(1→4)-<em>N</em>-acetyl-<small>D</small>-glucosamine.
