A -Acetylgalactosamine

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. [Pg.234]

Griggs and coworkers studied hydrolysis with 3 M hydrochloric acid for 3 h at 100° of canine submaxillary mucin (CSM) and CSM mixed with a standard sugar mixture. Sugar recoveries were 76.0% for fucose, 76.6% for mannose, 84.3% for galactose, 82.5% for A -acetylglucosamine, and 87.7% for A -acetylgalactosamine. [Pg.261]

Sasaki and coworkers have examined reversible metal coordination as a mechanism for DCL generation in the presence of lectin biomolecules [49,50]. The use of metal ions in reversible processes is canonical to supramolecular chemistry, and has been explicitly demonstrated for doublelevel orthogonal DCLs by Lehn and Eliseev [51]. Sasaki s system is designed around octahedral Fe(II) bipyridine complexes. The bipyridine-modified A-acetylgalactosamine (bipy-GalNAc) (78) was found to trimer-ize in the presence of Fe(II) to afford a 3 1 mixture of the fac (79) and mer (80) diastereoisomers, each as a racemic mixture (A+A) (Scheme 2.12). [Pg.74]

This enzyme [EC 3.1.6.12] acts on 4-sulfate groups of the A-acetylgalactosamine 4-sulfate moieties in chondroitin sulfate and dermatan sulfate. [Pg.9]

The methodology of Gao and Sharpless <1988JA7538> is equally applicable to glycosamines the cyclic sulfate of methyl a-D-iV-acetylgalactosamine 67 was prepared from methyl a-D-A -acetylgalactosamine 254 (Equation 26) <2003AGE5209>. [Pg.892]

Diseases that result from specific enzyme deficiencies are as follows (1) GM, gangliosidosis (2) GM2 gangliosidosis (Tay-Sachs disease) (3) sialidosis (4) Fabry disease (5) Gaucher disease (6) Niemann-Pick disease (7) Krabbe disease (8) metachromatic leukodystrophy (9) Farber disease. Cer, Ceramide Glc, glucose Gal, galactose GalNAc, A -acetylgalactosamine NANA, N-acetyfiieuraminic acid. Figure 16-5. The pathway of sphingolipid catabolism.

Tay-Sachs disease, the lipid storage disease that afflicts 1 in 900 children of Ashkenazic Jewish parents, results in the accumulation of the ganglioside ceramidc-/3-glucose-/3-galactose-A-acetylgalactosamine /V-acetylneuramic acid in the brain. Why does this occur ... [Pg.397]
