Now, the problem with the problem drawing aromatosaccharides in the following manner is the fact that the stereo chemistry is not actually seen, because all these bonds seem to lie along the same plane. But we know that sugar molecules are three dimensional molecules. They have stereo chemistry. And to describe the stereo chemistry of sugar molecules correctly, the most common mechanism we use are the fissure projections. So fissure projections are commonly used to describe the stereo chemistry, the three dimensional arrangement of the atoms and the bonds within the sugar molecule. And to see what the fissure projection actually looks like, let's take a look at the following molecules.
