Short description: Sugar containing three carbon atoms
D-Glyceraldehyde is an aldotriose because the carbonyl group is at the end of the chain
Dihydroxyacetone is a ketotriose because the carbonyl group is the center of the chain.
A triose is a monosaccharide, or simple sugar, containing three carbon atoms. There are only three possible trioses: the two enantiomers of glyceraldehyde, which are aldoses; and dihydroxyacetone, a ketose which is symmetrical and therefore has no enantiomers.[1]
Trioses are important in cellular respiration. During glycolysis, fructose-1,6-bisphosphate is broken down into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate. Lactic acid and pyruvic acid are later derived from these molecules.[2]
