Triose 

A triose is a monosaccharide containing three carbon atoms. There are only two trioses, an aldotriose (glyceraldehyde) and a ketotriose (dihydroxyacetone). Trioses are important in respiration. Namely, lactic acid and pyruvic acid are derived from aldotriose and ketotriose, respectively.

The D-aldotriose is D-Glyceraldehyde

The ketotriose is dihydroxyacetone:
