Hi,

I would like to request the addition of the term 'peptidoglycan' to the ontology. More details about this polymer may be found here:

All the best,

Bernard

Peptidoglycan (CHEBI:8005) will be visible in the next ChEBI release. I put the definition from the IUPAC Gold Book:

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.
