• 説明

  N-Acetyl-D-Glucosamine is the N-acetyl derivative of glucosamine.Chemically it is an amide between glucosamine and acetic acid. A single N-acetlyglucosamine moiety linked to serine or threonine residues on nuclear and cytoplasmic proteins -O-GlcNAc, is an ubiquitous post-translational protein modification. O-GlcNAc modified proteins are involved in sensing the nutrient status of the surrounding cellular environment and adjusting the activity of cellular proteins accordingly. O-GlcNAc regulates cellular responses to hormones such as insulin, initiates a protective response to stress, modulates a cell's capacity to grow and divide, and regulates gene transcription. In humans, it exists in skin, cartilage and blood vessel as a component of hyaluronic acid, and bone tissue, cornea and aorta as a component of keratan sulfate.
  N-Acetyl-D-glucosamine (D-GlcNAc) is a derivitized glucose monomer found in polymers of bacterial cell walls, chitin, hyaluronic acids and various glycans. It is also synthesized in the glycosylation pathway as uridine diphosphate (UDP-GlcNAc), which can then be released following degradation of glycosylated proteins.D-GlcNAc is used to identify, differentiate and characterize N-acetyl-β-D-hexoaminidase(s). It is also used in the treatment of osteoarthritis and inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease. Further, it is used as a substrate in sialic acid production, cosmetics and in drug development research.

• 使用

  N-Acetyl-D-glucosamine is used in the identification and characterization of N-acetyl-beta-D-hexoaminidase. It is also used in the treatment of osteoarthritis and inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease. Further, it is used as a substrate in sialic acid production, cosmetics and in drug development research.

• 定義

  ChEBI: N-acetyl-D-glucosamine is the D isomer of N-acetylglucosamine. It has a role as a bacterial metabolite. It is a N-acetylglucosamine and a N-acetyl-D-hexosamine.

• 一般的な説明

  N-Acetylglucosamine (GlcNAc) is a monosaccharide, derived from glucose and undergoes linear polymerization by (1,4)-β-linkages to form the polymer chitin. It is also a component of heterogenous polysaccharides, such as murein and hyaluronic acid. N-acetylglucosamine exhibits anti-inflammatory properties and is considered as a potential drug in the treatment of osteoarthritis. Its antiarthritic mode of mechanism involves the suppression of IL-1β (Interleuken-1β)-induced NO (nitric oxide), cyclooxygenase-2 (COX-2), and IL-6 production by inhibition of expression of iNOS (inducible nitric oxide synthase) protein and mRNA.
