A
glycosaminoglycan formed by alternating residues of
d-glucosamine and either muramic acid {2-amino-3-
O-[(
S)-1-carboxyethyl]-2-deoxy-
d-glucose} or
l-talosaminuronic acid (2-amino-2-deoxy-
l-taluronic acid), which are usually
N-acetylated or
N-glycoloylated. The carboxyl group of the muramic acid is commonly substituted by
a peptide containing residues of both
l- and
d-amino acids, whereas that of
l-talosaminuronic acid is substituted by a peptide consisting of
l-amino acids only.
