NB The SNFG depiction of this compound by GlyTouCan depicts N-acetylmuramic acid groups instead of the 2-acetamido-3-O-[(R)-lactoyl]-beta-D-glucopyranosyl groups shown in both the SID (submitted by GlyTouCan) and CID entries in PubChem. It is not clear which compound is intended. It is an amino tetrasaccharide and a member of acetamides."}]
