Glucosamine containing

The synthesis of some mannose- and glucosamine-containing glycoproteins consequently decreases. ... 

The results presented here show that the glycosphingolipids of chicken pectoral muscle differ from those of human skeletal and cardiac muscles. In addition, we are presenting the structures of two glucosamine-containing gangliosides which were characterized by enzymatic hydrolysis and methylation studies.

The metabolic disorder in Morquio-Ullrich s disease differs from that in Hurler s syndrome since substantial quantities of keratan sulfate have been identified (P2) in the urine of patients with this disease. The identification of the mucopolysaccharide was based on chemical, chromatographic, and infrared spectral data. In view of this rigorous characterization, it seems likely that the glucosamine-containing mucopolysaccharide reported by other workers (M6) in the urine of cases of this disease is also keratan sulfate.

Glucosamine-containing polymers, which are formed from precursors such as uridine 5 -diphospho-Af-acetyl-D-glucosamine (UDP-GlcNAc), play key roles in cellular metabolism and intercellular signaling. 

Chondroitin sulfates B and C, a small amount of a glucosamine-containing sulfated mucopolysaccharide, and hyaluronic acid were found in human umbilical cord (Danishefsky and Bella, 1966). Characterization of the chondroitin sulfate B was based on characteristic bands at 928, 860, and 840 cm" chondroitin sulfate C was identified by bands at 825 and 1000 cm". ...

The D-glucosamine-containing sialyl glycopeptide 0-a-D-NeupNAc- ( 2- 6) -0-/3-D-Galp- (l- 4) -o- -D-GlcpNAc- (l->4) -L-Asp has been made by successive specific glycosylations from the glucosaminyl amino acid. A more complex but related compound (6)... 

Several other variants of basic ganglioside structures have been reported. Glucosamine-containing gangliosides have been detected since the very early studies (reviewed by Martensson, 1969). The structures of four of these gangliosides have been elucidated recently (Li et al., 1973 Wiegandt, 1973, 1974).
