In water, d-glucose exists as an equilibrium mixture of three different structures, an open chain structure (present in trace amounts) and two chair conformational structures, one present in a ~64% amount and the other in a 36% amount. draw each of the structures in question and comment on why there is a greater amount of one cyclic structure present over the other. also explain why there is so little of the open chain structure present in the mixture. (i) (12 mark in relation to the three structures drawn in (i) above, explain the (5 mark (ii) phenonomen "mutarotation of d-glucose". in your answer it is necessary to quote appropriate specific rotation values. (8 mar in relation to the two cyclic structures you have drawn, explain (iii) the terms diastereomers; anomers; heterocycles; chiral centres reducing sugars. q6. answer all parts.
