cyclizing pyran

Carbohydrate Derivative Compounds

Fructose Ketohexose, is Cyclized by reaction between carbon 1 and 4, this form is derived from furan, furan is the form (Figure 3). Glucose but also the D-glucofuranose is not stable and is rapidly becoming D-glucopyranose. The dare is cyclizing furan form (furanose) are:

  • The ribose giving ribofuranose.
  • The 2-deoxyribose 2-giving desoxyribofuranose.
  • Fructose giving fructofuranose.
  • Generally, it is Ketohexose.

The dare is cyclizing pyran form (Pyranose) are:

  • Glucose giving glucopyranose.
  • Galactose giving galactopyranose.
  • Generally, it is Aldohexose.
