Application

N,N′,N′′-Triacetylchitotriose has been used:
  • as a competitive inhibitor of the enzymatic activity of lysozyme to treat Macrophages to inhibit the constitutively lysozyme production
  • to dock the catalytic cleft of Cel9A (endocellulases)
  • as an inhibitory sugar to access the specificity of labelling with gold complexed lectin

Biochem/physiol Actions

N,N′,N′′-Triacetylchitotriose is a chitin oligosaccharide, that promotes lysozyme inhibition. Chitin oligosaccharides are associated with many physiological functions. They are biodegradable and are useful in identifying chitin polysaccharides and associated glycoconjugates.
