1927 Goodyear & Haworth in Jrnl. Chem. Soc. 3141 On the basis of the conclusions now reached, the formula (A) must be accepted as a general representation of a normal sugar, which might be described as a pyranose.
1953 J. S. Fruton & S. Simmonds Gen. Biochem. xvii. 380 The open-chain form [of fructose]..is in equilibrium with the corresponding pyranose and furanose forms; in solutions of the free sugar, the pyranose form predominates.
1974 J. B. Finean et al. Membranes & Cellular Functions ii. 30 The minimal structural requirements for a molecule to be recognized by the sugar transport system in mammalian intestine are met by 6 carbon pyranose sugars bearing a hydroxyl on carbon 2.
2005 M. K. Campbell & S. O. Farrell Biochem. (ed. 5) xvi. 439 The six-membered rings of pyranoses actually exist in solution in the chair conformation.
