WebA Fischer projection may not be rotated by 90 degrees. Such a rotation typically changes the configuration to the enantiomer. To find the enantiomer of a molecule drawn as a Fischer projection, simply … Two older prefixes still commonly used to distinguish diastereomers are threo and erythro. In the case of saccharides, when drawn in the Fischer projection the erythro isomer has two identical substituents on the same side and the threo isomer has them on opposite sides. When drawn as a zig-zag chain, the erythro isomer has two identical substituents on different sides of the plane (anti).

"WebA Fischer projection is a drawing of a 3D molecule as a flat structure. The chiral carbons are represented by crossed lines. In addition to carbohydrates, it is useful for other molecules that have two or more chiral carbons. Fischer projections are useful for differentiating between enantiomers, diastereomers, and meso compounds. " - Fischer projection diastereomers
