Circle the correct answers for the questions related to glucose:
Which is the most abundant isomer in water?
Which hydroxyl group on the acyclic structure is involved in the cyclization?
Homework Answers
explanation :
1) in water beta -D-glucose is more stablt so circled compound is beta D-glucose
2) total ring contain 5 atoms . so 4th carbon -OH is participating in cyclization
