Q. 13.7
Question
What are the functional groups and number of carbons in a ketopentose?
Step-by-Step Solution
Verified Answer
A ketopentose contains a ketone group and a carbon atom.
1Step 1: Introduction
- Ketoses are monosaccharides with a ketone institution connected to every molecule.
- If the carbonyl institution is close to the stop of the chain, ketoses can isomerize into aldoses.
- Fructose and ribulose are examples of ketoses.
2Step 2: Ketopentose
- The 2-position of a pentose has a single ketone group.
- A five-carbon monosaccharide with an aldehyde group at position 1 (aldopentose) or a ketone group at position 2 (ketopentose) (ketopentose).
3Step 3: Determine the functional group and number of carbon in ketopentose
Keto refers to a ketone group, while pentose refers to a five-carbon chain.
