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.

D-N-Acetylgalactosamine (N-Acetyl-D-galactosamine) is an important constituent of brain heteropolysaccharides (glycoproteins).

N-Acetyl-D-galactosamine-6-phosphate (disodium) is a galactosamine phosphate involved in galactose metabolism and the phosphotransferase system (PTS), which can be hydrolyzed by NagA.

N-Acetyl-D-Galactosamine-[13C6] (Standard) is a reference standard of N-Acetyl-D-Galactosamine-[13C6] intended for quantitative analysis, quality control, and related biochemical research applications.

1β-Methylseleno-N-acetyl-D-galactosamine (MeSebGalNac) is a nucleoside metabolite.

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.

GalNac-L96 triethylamine salt is a trivalent N-acetylgalactosamine (GalNAc) ligand for the asialoglycoprotein receptor (ASGPR).

GalNAc-L96 is a triantennary N-acetylgalactosamine (GalNAc) ligand for asialoglycoprotein receptors (ASGPR) that lacks sialic acid.

UDP-GalNAc disodium is a key sugar nucleotide and serves as the catalytic substrate of EpsC115 (a truncated mutant protein of extracellular polymeric substance (EPS) with amino acids 1–115 at the N-terminus). It is a universal glycosyl donor for various N-acetylgalactosaminyltransferases, mediating the transfer of GalNAc groups from nucleotide sugars to carbohydrate or polypeptide receptors and providing essential glycosyl precursors for various glycosylation modification reactions. At present, UDP-GalNAc disodium has been widely applied in mechanism research of colorectal cancer, breast cancer and other tumors.

DNJNAc, also known as 2-Acetamido-1,2-dideoxynojirimycin, is a highly potent and specific inhibitor of β-hexosaminidase (HEX). HEX enzymes catalyze the hydrolysis of terminal non-reducing N-acetyl-β-D-glucosamine (GlcNAc) and N-acetyl-β-D-galactosamine (GalNAc) residues from glycoconjugates such as glycoproteins, gangliosides, and glycosaminoglycans. HEX secreted by chondrocytes into the extracellular space contributes to cartilage matrix degradation, and HEX activity is elevated in the synovial fluid of osteoarthritis patients.

1,3-β-Galactosyl-N-acetylhexosaminephosphorylase (EC 2.4.1.211) catalyzes the reaction that uses β-D-pyranogalactosyl-(1→3)-N-acetyl-D-galactosamine as its substrate to produce N-acetyl-D-galactosamine.

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.
