Webwhich is similar to the structure of glucose chair con-formation (Figure 4(b)) with the exception of the C1 site. This result is in agreement with the report[31] that the restraint of the planar carbonyl group imposes a dis-torted half-chair conformation on … WebFormation. The pyranose ring is formed by the reaction of the hydroxyl group on carbon 5 (C-5) of a sugar with the aldehyde at carbon 1. This forms an intramolecular hemiacetal.If reaction is between the C-4 hydroxyl and the aldehyde, a furanose is formed instead. The pyranose form is thermodynamically more stable than the furanose form, which can be …
