A sweet crystalline compound that exists in solution as the monomeric dihydroxy aldehyde HOCH₂CHOHCHO in dextrorotatory, levorotatory, and racemic forms but in the anhydrous state only as the crystalline dimer C₆H₁₂O₆, that is formed as an intermediate in carbohydrate metabolism by the breakdown of sugars, that yields glycerol on reduction, and that may be regarded as a triose and the simplest aldose capable of existing in both D- and L-stereoisomeric forms, which serve as reference standards for differentiating the stereoisomeric forms of all other sugars and also of other stereoisomeric compounds.  8, fiche 2, Anglais, - glyceraldehyde
