Pick up the correct statements from the following.
(i) Glucose exists in two different crystalline forms, 
-D-glucose and β-D-glucose.
(ii) 
-D-glucose and β-D-glucose are enantiomers.
(iii) Cellulose is a straight chain polysaccharide made up of only β-glucose units.
(iv) Cyclic structure of 
-D-glucose and β-D-glucose is called pyranose structure.
Text Solution
Verified by ExpertsB
-D glucose and β-D-glucose are two cyclic hemiacetal forms of glucose which differ only in
configuration of hydroxyl group at anomeric carbon. Thus, 
-D-glucose and β-D glucose are anomers and not enantiomers.
Cellulose consists of 1, 4 - β-glycosidic linkages. Hence, , , and are correct while is not correct.
