Identify the following compound:
β - D - (-) - Fructofuranose
β - D - (+) - Glucopyranose
α - D - (-) - Fructofuranose
α - D - (+) - Glucopyranose
The given carbohydrate is α - D - (-) - Fructofuranose. This is because the -OH group is present on the right hand side.
How many hydroxyl groups present in α−D(−) fructofuranose ?
