Synthesis of chitin and chitosan stereoisomers by thermostable α-glucan phosphorylase-catalyzed enzymatic polymerization of α-D-glucosamine 1-phosphate.
The relationship between two aminopolysaccharide stereoisomers, namely α-(1→4)- and β-(1→4)-linked (N-acetyl)-D-glucosamine polymers, is of significant interest within the field of polysaccharide science, as they correspond to amino analogs of the representative abundant natural polysaccharides, viz. amylose and cellulose. While the latter glucosamine polymer is the basis of well-known natural ...
متن کاملCharacterization of dimers of hydroquinone glucosides produced by peroxidase-catalyzed polymerization.
4'-Hydroxyphenyl alpha-glucoside and 4'-hydroxyphenyl beta-glucoside were polymerized with horseradish peroxidase. The isolated dimers were found to have linkages at C3' of the hydroxyphenyl moieties and proved to be fluorescent. Low accumulation of oligomers was attributed to increasing electrochemical reactivity with polymerization degrees, which were expected from the levels of highest occup...

Enzymatic production of defined chitosan oligomers with a specific pattern of acetylation using a combination of chitin oligosaccharide deacetylases
Chitin and chitosan oligomers have diverse biological activities with potentially valuable applications in fields like medicine, cosmetics, or agriculture. These properties may depend not only on the degrees of polymerization and acetylation, but also on a specific pattern of acetylation (PA) that cannot be controlled when the oligomers are produced by chemical hydrolysis. To determine the infl...
