Oxidation maltose

One notices that the data from the oxidation of melezitose by per-iodic acid confirm the pyranose structure of the D-glucose unit in turanose, and therefore also in the case of maltose, in agreement with the original assignments for both of these disaccharides from methylation studies. [Pg.49]

The rate of oxidation of ethylene glycol was found268-269 to attain a broad maximum between pH 2.5 and 6. In a very complete study of the effect of pH on the periodate oxidation of carbohydrates, Neumiiller and Vasseur260 showed that the oxidation of maltose, melibiose, methyl a-D-... [Pg.30]

Lewis201 postulated maltosone as the first product in the oxidation of maltose by Fehling solution, but no osone was detected when maltose was treated with Fenton s reagent.23 Oxidation of maltosone with bromine water gave 2-oxo-maltobionic acid, isolated as its brucine salt.191... [Pg.90]

A liquid membrane bioreactor was developed as a means of encapsulation for a multi-enzyme system incorporating an oxidation and carbohydrate cleavage, demonstrated using a-glucosidase and glucose oxidase in the conversion of maltose to gluconic acid ... [Pg.53]

Oxidative, degradative reactions of maltose have been studied,136-138 and reviewed in this Series,139-142 and this subject will not, therefore, be discussed. The selective oxidation of primary52,143-146 and secondary66,147 hydroxyl groups in maltose has been investigated. The synthesis143 of maltouronic acid, 4-0-(a-D-glucopyranosyluronic... [Pg.246]

Microbial oxidation of maltose by Agrobacterium tumefaciens to give 4-0-(a -D-rtbo-hexosyl-3-ulose)-D-glucose (62) has been reported.147 Chemical oxidation of methyl, 2,6,2, 3, 4, 6 -hexa-0-acetyl-... [Pg.246]

Stodola, F. H. and Lockwood, L. B. 1947. The oxidation of lactose and maltose to bionic acids by pseudomonas. J. BioL Chem. 171, 213-221. [Pg.340]

Bromine oxidation of maltose followed by methylation and hydrolysis gives 2,3,4,6-tetra-O-methyl-D-glucopyranose and a tetramethyl-D-gluconic acid, which readily forms a -y-lactone. [Pg.932]

Some microorganisms effect the oxidation of oligosaccharides to glycosid-3-uloses this conversion has been reported for maltose, lactose, and their respective aldobionic acids. Conditions for the oxidation of sucrose by the action of Agrobacterium tumefaciens have been improved and optimized on a molar scale, so that 3-ketosucrose can be produced in 40% yield 449... [Pg.270]
