Threose is a monosaccharide selected from the group of tetroses. There are two stereoisomers, D- threose, L- threose, and. The IUPAC name of the D-form is (2S, 3R) -2,3,4 - Trihydroxybutanal. L- Threose [ Synonym: (2R, 3S) -2,3,4 - Trihydroxybutanal ] has little meaning. The erythrose is a diastereomer of Threose.

The stereochemical configuration of the Threose is eponymous for the threo- descriptor, which is used as a semi- systematic name suffix to identify similarly configured molecules.

Reactions

In the oxidation of threose, for example with nitric acid, tartaric acid occurs. During the reduction, for example with sodium borohydride, produced threitol.
