N-아세틸-D-글루코사민

개요N-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.

용도N-acetyl-D-Glucosamine (GlcNAc) is a monosaccharide derivative of glucose. It is released by the action of O-GlcNAcase, in mammalian systems from proteins that have been post-translationally modified with O-GlcNAc.D-GlcNAc enhances the proliferation and collagen expression of fibroblasts, reduces hyperpigmentation and is therefore considered a valuable ingredient in cosmetics for improving skin wrinkles and color.Important substrate for the production of sialic acids.Used in multiple other applications in drug development and food supplement, based on a newly described bio-wave model.

일반 설명N-Acetyl-D-glucosamine (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.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
