    Study Notes

    Optical Stereoisomers of Sugars

    • D-sugars are a type of optical stereoisomer, characterized by the OH group attached to the chiral carbon being on the right side.
    • L-sugars are also a type of optical stereoisomer, characterized by the OH group attached to the chiral carbon being on the left side.
    • The D and L forms of sugars are differentiated based on the orientation of the OH group attached to the chiral carbon.
