Study Notes
Stereoisomers of Sugars
- D-sugars have the OH group attached to the chiral carbon on the right.
- L-sugars have the OH group attached to the chiral carbon on the left.
- The D and L forms of sugars are termed optical stereoisomers.

Description
Learn about the D and L forms of sugars, which are optical stereoisomers distinguished by the position of the OH group attached to the chiral carbon. In D-sugars, the OH group is on the right, while in L-sugars, it is on the left.
