Enzymatic Synthesis of Novel Disaccharides Using Disaccharide Phos phorylases.
Journal of Bioscience and Bioengineering, 2000A method for the synthesis of novel disaccharides was developed. It involved the following two steps. The first step consisted of two continuous reactions: the conversion of maltose to beta-D-glucose-1-phosphate and D-glucose by the phosphorolytic activity of maltose phosphorylase and the specific consumption of only D-glucose by incubation with ...

Disaccharide Digestion and Maldigestion
Scandinavian Journal of Gastroenterology, 1996All food carbohydrates are hydrolysed to monosaccharides before transport across the microvillus membrane. The digestion of disaccharides and some oligosaccharides is undertaken by a number of small intestinal brush border enzymes: sucrase-isomaltase, lactase phlorizinhydrolase, maltase-glycoamylase and trehalase. The distribution of the enzymes in the

Hydroxymethyl Rotamer Populations in Disaccharides.
ChemInform, 2003Sixteen methyl glucopyranosyl glucopyranoside disaccharides (methyl beta-d-Glcp(p-Br-Bz)-(1-->x)-beta/alpha-d-Glcp) containing beta-glycosidic linkages (1-->2, 1-->3, 1-->4, and 1-->6) were synthesized and analyzed by means of CD and NMR spectroscopy in three different solvents.

Synthesis of the Polyketomycin Disaccharide (I).
ChemInform, 2003Abstract The disaccharide portion of the anthracycline antibiotic polyketomycin consists of the trideoxy sugar d -amicetose attached to the methyl-branched sugar l -axenose. The polyketomycin disaccharide was synthesized from methyl 2,3,6-trideoxy-α- d - erythro -hexopyranoside (methyl α- d -amicetoside) and phenyl 3,4-di- O -benzyl-2,6-dideoxy-3 ...
