Determination of xylitol, on Kieselgur G in 0.01 M phosphate buffer, pH 5.0, a recommended procedure involves the development in butanol-acetone-buffer (4:5:1). Xylitol can then be analyzed qualitatively or semiquantitatively by spraying with ethanol-H.SO.-anisaldehyde (9:0.5:0.5).Intuitive 发表于 2025-3-27 03:56:51

Determination of xylitol,he third is based on titrimetry. Most methods serve the determination of other polyols as well. So, for example, sugar alcohols have been chemically determined by iodometric titration and by gas liquid chromatography after acetylation with acetic anhydride in pyridine .

Occurrence and significance of polyols,sugar alcohols and improved assay methods, it is now realized that xylitol is a ubiquitous carbohydrate. The present literature on the occurrence of xylitol in nature will most likely increase rapidly during the forthcoming years. Xylitol and certain other polyols are of vital importance to the life多产鱼 发表于 2025-3-27 23:42:34
Xylitol in dietetics and medicine, normal metabolite in mammals. This idea was supported by the discovery of a very active enzyme system for the reduction of L-xylulose to xylitol . It was also found that D-xylulose 5-phosphate, rather than Dribulose 5-phosphate, is the ketopentose substrate of transketolase in the 6phosphoglucINCUR 发表于 2025-3-28 02:56:28
