Interpretation Introduction

Interpretation:

The given compound should be identified whether it is a reducing sugar or not.

Concept introduction:

For the carbohydrates,

  • Anomeric position is carried by an OH group for Hemiacetals.
  • Anomeric position is carried by an alkoxy group for acetals.
  • Hemiacetal sugars are in equilibrium with their open chain form.
  • acetal sugars are not in equilibrium with their open chain form.
  • Open chain form of sugars can reduce certain oxidizing agents (Tollens’, Fehling’s and Benedict’s) are called reducing sugars.
