Fischer Projections of L-Erythrose
All of the images below are for L-erythrose. Rotate the images so see how the
3-dimensional model correlates with the three Fischer projections beneath it.
The excercise demonstrates how all nine projections are for the same molecule.
All are correct. It is a matter of perspective which one is drawn. The convention
for sugars is to use the first projection on the left, with the aldehyde or ketone
on top and the CH2OH on the bottom. For typical organic molecules there is no
convention for which perspective is best.
Red = Oxygen, Grey = Carbon, White = Hydrogen
