Interpretation Introduction

Interpretation:

The name of the given Haworth projection of a compound should be determined.

Concept introduction:

• Haworth projection is used to represent sugars in their cyclic forms.
• Name for a Haworth projection,
  • α-indicates the –OH group of anomeric carbon C1 and ${\text{-CH}}_{\text{2}}\text{OH}$ substituent on the C5 carbon is trans to each other.
  • D indicates the ${\text{-CH}}_{\text{2}}\text{OH}$ substituent on the C5 carbon is on up position.
  • The right side and left side –OH groups of chiral carbons in fisher projection are drawn as down side and upward side respectively.
