Chair Conformation For Glucose, Previous hypotheses on the conformation of a-l4-polyglucoses were actually based on the assumption that the stability of the two boat Bl and 3B forms of the a-D-glucopyranose ring was comparable to that of the chair Cl form235 In the light of more recent knowledge on conformational analysis28 it appears that the energy difference between a chair and a boat or skew form is far from being small. Glucose chair conformation In the case of glucose the mutarotation gives 36 percent a 64 percent p and negligible strciight chain. If the number of heavy axial groups becomes smaller when the conformation is changed to 1C4 all equatorial groups in 4C1 become axial and vice versa then it is likely that the conformation is 1C4.
