and K represents the residue of a ketose sugar, together with a process for producing N-glycosides of aldose and ketose sugars containing from 5 to 7 carbon atoms in the sugar moiety by reacting in an inert solvent an N-glycoside forming base with a 3-O-acyl ketose, 2-O-acyl aldose ...

I2-Catalyzed Oxidative Condensation of Aldoses with Diamines: Synthesis of Aldo-Naphthimidazoles for Carbohydrate Analysis A novel method for the conversion of unprotected and unmodified aldoses to aldo-imidazoles has been developed. Using iodine as a catalyst in acetic acid so... C Lin,WT Hung...
To date, only one kind of dihydroxyacetone phosphate (DHAP)-dependent aldolases has been discovered and applied to synthesize branched-chain sugars directly using DHAP and dihydroxyacetone (DHA) as substrate. However, the unstable and high-cost properties of DHAP limit large-scale application. ...
摘要: PURPOSE: To obtain an isomerized glucose syrup, etc., by safely and efficiently isomerizing a compound having aldose structure with a specific organic germanium compound into a compound having ketose structure without necessitating particular apparatuses and complicate operations....
preparation of innovative branched-chain sugars due to the direct and rapid creation of molecular complexity in benign environments [7]. DHAP-dependent aldolases exhibit a strict specificity for the donor DHAP [20]. However, compound DHAP is unstable [21] and currently very expensive. These ...
Since sorbitol in humans is derived from reduction of glucose by aldose reductase (AR), inhibitors of AR have been developed for clinical use to prevent sorbitol accumulation and minimise diabetic complications. Until recently, only indirect evidence pointed to the ability of polyols to protect ...
