Illustration of the isomers of butane-1,2,3,4-tetrol using the 2D Fisher projection (top), structural formula (middle) and 3D structure (bottom) for meso-erythritol (A), D-threitol [(2R,3R)-butane-1,2,3,4-tetrol] (B) and L-threitol [(2S,3S)-butane-1,2,3,4-tetrol] (C). The 3D structure is based on the crystal structures of meso-erythritol (MERYOL03), D-threitol (PAGDEG) and L-threitol (LEDPUF).
