Concept explainers
a)
Interpretation:
Fischer projection of D-sugars are to be drawn.
Concept introduction:
Fischer Projections are typically used for depicting monosaccharides and amino acids. They are helpful with depicting monosaccharides, because they have so many stereocenters, and the different monosaccharides are all pretty similar, they are just different about the orientation of the stereocenters. The Fischer Projection allows us to quickly see the orientation of each monosaccharide.
