Acetylglucosamine

Fig. 2. Generalized structure of N-linked oligosaccharide of the pituitary glycoprotein hormones. SO = sulfate, GIcNAc = N — acetylglucosamine, GalNAc = N — acetylgalactosamine, Man = mannose, Fuc = fucose, SA = sialic (neuraminic) acid.

IV-Acetylglucosamine and IV-Acetylmuraniic acid Sugar derivatives in the peptidoglycan layer of bacterial cell walls. 

Once formed, an acyl CoA is a substrate for further nucleophilic acyl substitution reactions. For example, iV-acetylglucosamine, a component of cartilage and other connective tissues, is synthesized by an aminolysis reaction between... 

Disorders caused by mislocalization of lysosomal proteins (e.g., mutations in the N-acetylglucosamine 1-phosphotransferase leading to inclusion cell disease). 

Peculiar characteristics of chitins and chitosans are hemostatic action, anti-inflammatory effect, biodegradability, biocompatibihty, besides antimicrobial activity, retention of growth factors, release of glucosamine and M-acetylglucosamine monomers and oligomers, and stimulation of cellular activities [11,12,295-297]. 

GalNAc, Gal, GlcNAc, Hex and HexNAc are the abbreviations used when discussing sequences of monosaccharides and represent A-acetylgalactosamine, galactose, A-acetylglucosamine, hexose, i.e. a monosaccharide with six carbon atoms, and A-acetylhexosamine, respectively.
