Question

Quizplus · Accepted Answer

Glyceraldehyde is the reference compound for naming D and L isomers of sugars. This is because it is the simplest carbohydrate with a chiral center, and its two stereoisomers are designated as D-glyceraldehyde and L-glyceraldehyde. Other sugars are classified as D or L based on their similarity to the D or L configuration of glyceraldehyde.
