10 Jun 2004TL;DR: In this article, an aldose having n-1 carbon atoms is produced from aldonic acid having n carbon atoms using hypochlorous acid or a hypochchlorite in a high yield at low cost with safety, by treating the reaction mixture with a compound having reactivity higher than that with the produced aldoses.
Abstract: An aldose having n-1 carbon atoms is produced from an aldonic acid having n carbon atoms using hypochlorous acid or a hypochlorite in a high yield at low cost with safety, by treating the reaction mixture with a compound having reactivity with the hypochlorous acid or hypochlorite higher than that with the produced aldose.

TL;DR: The extended periods required for theoretical periodate consumption coupled with the marked interference of both periodate and iodate in the conventional colorimetric method for glycolaldehyde determination have rendered this technique either equivocal or impractical.
Abstract: THE mechanism of action of periodate on sugar phosphates has not been fully established and there is some controversy regarding the origin of the products of periodate action1,2,3. The convenient identification by chemical techniques of sugars esterified to phosphates at their terminal carbon atom depends on their oxidation by periodate to yield glycolaldehyde phosphate which may be identified by colorimetric procedures4. The extended periods required for theoretical periodate consumption coupled with the marked interference of both periodate and iodate in the conventional colorimetric method for glycolaldehyde determination (Fig. 1) have rendered this technique either equivocal or impractical. Treatment of aldose or ketose phosphates with sodium borohydride yields the corresponding polyol phosphates which are readily cleaved by periodate with theoretical consumption of oxidant generally occurring within 30 minutes.

TL;DR: In this paper, a complex composed of nickel(II) and the optically active N,N′-diethylcyclohexane-1,2-diamine (chxn) showed ability to recognize the shape of molecules in terms of the configuration of the various OH groups in aldoses during the epimerization of D-glucose to D-mannose.

TL;DR: In this article, a therapeutic agent for diabetes containing ascorbic acid and an aldose reductase inhibitor as active ingredients was presented. But the active ingredients were not specified.
Abstract: PURPOSE: To obtain a therapeutic agent for diabetes comprising ascorbic acid or ascorbic acid and an aldose reductase inhibitor as active ingredients. CONSTITUTION: This therapeutic agent for diabetes contains ascorbic acid having hypermetabolism function of sorbitol as an intermediate metabolite of a polyol routine as an active ingredient. An aldose reductase inhibitor to form sorbitol as an intermediate metabolite of a polyol routine may be added. A polyol of a polyhydric sugaralcohol is formed by reduction of aldose saccharide, a sorbitol as a kind of a polyol promotes production in a high blood sugar state and causes diabetic complication. Ascorbic acid activates aldose reductase and sorbitol dehydrogenase, ascorbic acid and an aldose reductase inhibitor suppresses and inhibits production of sorbitol in the body and can prevent and diabetes and stop advance of stage.

TL;DR: In this article, a process for preparing a fructoside, especially fructsyl disaccharide, comprises reacting a fritosyl saccharide such as sucrose or raffinose with an alcohol or aldose in the presence of a Fructosyl-transferase, especially one derived from B. subtilis BCIB 11811, 11872 or 11873.
Abstract: A process for preparing a fructoside, especially a fructosyl disaccharide, comprises reacting a fructosyl saccharide such as sucrose or raffinose with an alcohol or aldose in the presence of a fructosyl-transferase, especially one derived from B. subtilis BCIB 11811, 11872 or 11873. In particular, aldose is a compound of the formulain which A represents a hydrogen atom or the group CH2X, where X represents a hydrogen atom or an alkoxy group, and the fructosyl disaccharide so formed is halogenated to provide a halosucrose or halogalactosucrose sweetener.
