Threose is a four-carbon monosaccharide or carbohydrate with molecular formula C4H8O4. It has a terminal aldehyde group rather than a ketone in its linear chain and so is considered part of the aldose family of monosaccharides. The threose name can be used to refer to both the D- and L-stereoisomers and more generally to the racemic mixture (D/L- equal parts D- and L-) as well as to the more generic threose structure (absolute stereochemistry unspecified).
