Description and Uses

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.
