Erythrose is a monosaccharide from the group of tetroses . Because of the terminal aldehyde group, erythrosis belongs to the aldoses . There are two stereoisomers , D -Erythrosis and L -Erythrosis . The IUPAC name of the D form is (2 R , 3 R ) -2,3,4-trihydroxybutanal. L- erythrosis [synonym: (2 S , 3 S ) -2,3,4-trihydroxybutanal] is of little importance. The Threose is a diastereomer to erythrose.

Erythrose was first isolated from rhubarb in 1849 by the French pharmacist Louis Feux Joseph Garot (1798–1869) and was so named because of its red color in the presence of alkalis (from ancient Greek ἐρυθρός, "red").

The stereochemical configuration of erythrosis gives its name to the descriptor erythro - which is used as a semi-systematic addition to the name to identify molecules with similar configurations. When "erythrosis" is mentioned in this text or in the scientific literature without any additional name ( prefix ), it means D -Erythrosis.

Reactions

Erythrose reacts slowly with hydrochloric acid to form lactic acid . In carbohydrate metabolism is erythrose 4-phosphate is an important intermediate.
