Core oligosaccharide

{
  "id": "MLC-T-CHM-002579",
  "term": "Core oligosaccharide",
  "field": "Chemistry",
  "definition": "The portion of a lipopolysaccharide (LPS) molecule in the outer membrane of Gram-negative bacteria that covalently links the lipid A moiety to the O-antigen polysaccharide chain. This structural component is composed of a short chain of sugar residues, including characteristic sugars like heptose and 2-keto-3-deoxyoctulosonic acid (Kdo). The structure of the core oligosaccharide is generally conserved within a bacterial genus, unlike the highly variable O-antigen.",
