n-acetyl-d-galactosamine

N-Acetyl-D-galactosamine (GalNAc) is a terminal essential amino sugar derived from galactose and forms the antigens of blood group A in humans.

β-D-Galactosyl-(1→3)-N-acetyl-D-galactosamine is a biochemical reagent used in glycoscience research. Glycoscience studies the structures, synthesis, biology, and evolution of sugars, encompassing carbohydrate chemistry, glycan formation and degradation enzymology, protein-glycan interactions, and the roles of glycans in biological systems. This field is closely connected to basic research, biomedicine, and biotechnology.

N-Acetyl-D-galactosamine-4-O-sulfate sodium salt is a biochemical reagent that can be used as a biomaterial for life science related research and as a sulfonylation reagent for organic synthesis and drug discovery.

O-Methyl-N-acetyl-2-deoxy-α-D-galactosamine (O-Methyl-N-acetyl-2-deoxy-a-D-galactosamine) is a biochemical reagent utilized in glycoscience research. This field explores the structure, synthesis, biology, and evolution of sugars, encompassing carbohydrate chemistry, glycan formation and degradation enzymology, and protein-glycan recognition, with significant connections to basic research, biomedicine, and biotechnology.

UDP-GalNAc (UDP-N-acetyl-D-galactosamine) disodium, a sugar nucleotide, serves as a substrate for EpsC115, an exopolymeric substances (EPS) N-terminal deletion mutant lacking residues 1-115. Additionally, UDP-GalNAc acts as the donor substrate for numerous N-acetylgalactosaminyltransferases, which transfer GalNAc from the nucleotide sugar to various saccharide or peptide acceptors [1].
