Identify the correct statement about glucose from following.
Identify the correct statement about glucose from following.
It is aldohexose.
It is nonreducing sugar.
It contains three chiral carbon atoms.
Its ring structure is hemiketal.
Solution
Explanation:
- Glucose is an aldohexose, meaning it is a six-carbon sugar with an aldehyde group.
- It is a reducing sugar, not nonreducing (since it can reduce other substances).
- It contains four chiral carbon atoms, not three.
- The ring structure of glucose is a hemiactal, not a hemiketal, because it forms from an aldehyde group, not a ketone.
