Definition
ChEBI: N-acetyl-D-galactosamine is the D-enantiomer of N-acetylgalactosamine. It has a role as a human metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a N-acetyl-D-hexosamine and a N-acetylgalactosamine.
Enzyme inhibitor
This acetylated aminosugar (FW = 221.21 g/mol), also known as 2acetamido-2-deoxy-D-galactopyranose and abbreviated D-GalpNAc and NAGA, is a component of many glycoproteins, chondroitin, and bloodgroup substances. N-Acetyl-D-galactosamine will also inhibit the binding of ligands to many lectins. Target(s): b-N-acetylhexosaminidase; a-N-acetylgalactosaminidase; discoidins I and II, or Dictyostelium discoideum agglutinins; Bauhinia purpurea agglutinin; lima bean (Phaseolus lunatus) lectin; Wistaria floribunda phytomitogen; horse gram (Dolichos biflorus) lectin; Sophora japonica hemagglutinin; soybean (Glycine max) agglutinin; snail (Helix pomatia) hemagglutinin; a-galactosidase B; b-N-acetylglucosaminidase; b-N-acetylgalactosaminidase; galactose oxidase, also alternative substrate; keratan sulfotransferase, weakly inhibited; aralin; rRNA N-glycosylase; peptidoglycan b-N-acetylmuramidase; polypeptide N acetylgalactosaminyltransferase.
