     The saccharides include such substances as dextrose and levulose, which are typical examples of the two classes into which these bodies are divisible, viz. the Aldoses and Ketoses.

Usage notes

This is not L-fructose, despite being named that way; it is D-fructose, due to the origins of stereochemistry and sugar research
