Pigman Chem. Carbohydrates ii. 52 The basic types of the furanoses are the pentoses. 1957E. V. Miller Chem. Plants i. 6 Glucose and other hexoses may exist in the form of a pyranose ring or a furanose ring, the former being the more stable form. 1963E. Percival in Florkin & Stotz Comprehensive Biochem. V. i. 24 Furanose forms of unsubstituted sugars have never been isolated although in solution they are considered to exist in equilibrium with the open-chain and pyranose ring forms. |
