(2R,3S,4R,5S)-2-methyloltetrahydropyran-3,4,5-triol - Reference Information
| Introduction | 1,5-anhydride-D-sorbitol, also called 1,5-anhydrous glucitol, is a reduction type in which one hydroxyl group is removed at the C- 1 position of glucopyranose. It is present in human cerebrospinal fluid, serum and plasma, and decreases in blood concentration during diabetes mellitus (DM). |
| biological activity | 1, 5-Anhydroborbitol is a reliable indicator for evaluating short-term blood glucose control. |
| use | intermediate of Tween -80 (polysorbate -80). |
| production method | this product is prepared by distillation of sorbitol under reduced pressure and intramolecular cyclition. |
