Official methods of analysis. Analysis of sugars was written by Anonymous. And the article was included in Bollettino dei Chimici dell’Unione Italiana dei Laboratori Provinciali, Parte Scientifica in 1979.Category: tetrahydropyran This article mentions the following:
Official Italian methods of anal. for the determination of loss of weight on drying, dry matter, reducing sugars, ash, and optical rotation are given for table sugar [57-50-1], glucose syrup, glucose monohydrate [14431-43-7], anhydrous glucose [50-99-7], and other sugars for human consumption. The total dry weight is determined refractometrically, and the reducing sugars by the Knight and Allen, Luff and Schoorl, and Lane and Eynon methods. Ash is determined by calcination at 525° in the presence of dilute H2SO4. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7Category: tetrahydropyran).
(2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7) belongs to tetrahydropyran derivatives. Dihydropyrans and tetrahydropyrans are examples of cyclic ethers widespread in nature. There is large number of marine macrolide natural products that contain tetrahydropyran and tetrahydrofuran ring together. For instance, goniodomin A (actin targeting polyether), prorocentrolide (toxin halistatins), and percentotoxineCategory: tetrahydropyran
