Describe the term D- and L-configuration used for sugars with examples.
Solution:
The configuration of D/L-Glucose was proved by the scientist Emil Fischer. D and L are absolute configurations of glucose.
D configuration is assigned to the sugars, in which the hydroxy group at the second last carbon is towards the right in the Fischer projection. L stands for sugars, in which the hydroxy group at the second last carbon is towards the left in the Fisher projection.
Therefore, glucose is D(+)-Glucose.
