n acetyl d glucosamine

N-Acetyl-D-Glucosamine (NAG) 是葡萄糖的单糖衍生物。

UDP-N-acetyl-D-Glucosamine is a natural nucleotide sugar that is used by glycosyltransferases to transfer N-acetyl-D-glucosamine residues to substrates.1It is an important component of antibiotic biosynthesis pathways in fungi and lipopolysaccharide production in bacteria.2,3 1.Roseman, S.Reflections on glycobiologyJ.

N-acetyl-α-d-glucosamine 1-phosphate disodium (GlcNAc-1-P) 为异位糖磷酸盐，关键中间体于N-糖蛋白生物合成。该化合物同时作为细菌细胞壁组分磷胆酸和鼠胺的代谢前体。

N-Acetyl-α-D-glucosamine是一种使用于生物化学研究的试剂。

N-Acetyl-D-glucosamine 6-sulfate (sodium) 是一种用于糖生物学研究的生化试剂。糖生物学涉及糖的结构、合成、生物学和进化，包括碳水化合物化学、聚糖形成和降解酶学、蛋白质-聚糖识别及其在生物系统中的作用。这一领域与基础研究、生物医学和生物技术密切相关。

Chitosan (MW 150000) (Deacetylated chitin) 是衍生自几丁质的聚阳离子线性多糖。它无毒，具有低致敏性，生物相容性和可生物降解性。它还具有抗肿瘤，抗细菌，抗真菌和抗氧化活性。

Hyaluronic acid (hyaluronan) 由玉米发酵得到，是由二糖的重复单元组成的生物聚合物，应用领域广泛。

NAGKi is an inhibitor of N-acetylmannosamine kinase (NAMK) and N-acetylglucosamine kinase (NAGK).

N,N'-Diacetylchitobiose, a dimer of β(1,4) linked N-acetyl-D glucosamine, is derived from the hydrolysis of chitin. This compound serves as an alternative carbon source for E. coli.

AB05831, also known as 2-Acetamido-1,2-dideoxynojirimycin, is a highly potent and specific inhibitor of beta-hexosaminidase. N-Acetyl-3-hexosaminidase (HEX) is a member of lysosomal hydrolases, which catalyzes hydrolysis of terminal, non-reducing N-acetyl-|3-D-glucosamine (GlcNAc) andN-acetyl-(3-D-galactosamine (GalNAc) residues in glycoproteins, gan-gliosides, and glycosaminoglycans (GAGs). HEX, released by chondrocytes into the extracellular compartment, promotes cartilage matrix degradation. Osteoarthritis patients have increased HEX activity in synovial fluid.
