D-Threose

Description:

D-Threose is a four-carbon aldose sugar, classified as a monosaccharide. It is an isomer of D-erythrose and is characterized by its specific stereochemistry, which includes two hydroxyl groups (-OH) attached to the second and third carbon atoms in its linear form. D-Threose exists in both an open-chain and cyclic form, with the cyclic form typically being a furanose. This sugar is soluble in water and exhibits sweet taste properties, similar to other sugars. D-Threose plays a role in various biochemical pathways and can be involved in the synthesis of nucleotides and other important biomolecules. It is less common than other sugars and is primarily of interest in research and biochemical applications. The CAS number 95-43-2 uniquely identifies D-Threose in chemical databases, facilitating its study and use in various scientific contexts. Its structural formula and properties make it a subject of interest in carbohydrate chemistry and biochemistry.
