Chapter 13: Q. 13.7 (page 435)

What are the functional groups and number of carbons in a ketopentose?

Short Answer

Expert verified

A ketopentose contains a ketone group and a 5carbon atom.

Step by step solution

01

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.
02

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).
03

Determine the functional group and number of carbon in ketopentose

Keto refers to a ketone group, while pentose refers to a five-carbon chain.
