Periodate Oxidation of Methylcellulose: Characterization and Properties of Oxidized Derivatives

In this paper, the behavior of oxidized methylcelluloses is compared with that of the initial methylcellulose, an amphiphilic cellulose derivative. Methylcelluloses are important for many applications in the cosmetic and food industries. The mechanism of thermo-gelation of methylcellulose is briefly explained as well as the method of oxidation of polysaccharides. Then, our experiments involve t...

THE OXIDATION OF HEXOSAMINES : d-GLUCOSAMINE AND d-GLUCOSAMINIC ACID

Metabolism of D-glucosamine and N-acetyl-D-glucosamine in the intact rat.

It has been demonstrated that n-glucosamine and N-acetyln-glucosamine are metabolized in animal tissues to n-fructose via phosphorylated intermediates (14). It has also been shown that n-glucose is converted to n-glucosamine and incorporated into glycoproteins and mucopolysaccharides (Pll), probably through formation of uridine diphosphate derivatives as intermediates (4). Little work has been ...

Periodate oxidation and macromolecular compaction of hyaluronan*

Partial periodate oxidation of hyaluronan (HA) leads to ring opening of the 4-linked D-glucuronate (GlcA) residues, providing a particularly flexible element within otherwise semi-flexible chains. This leads to compaction of the chains as demonstrated by a pronounced decrease in the intrinsic persistence length, which was determined on the basis of the molecular weight dependence of radius of g...
