WebFischer Projections and the D/L Notation: The first system for doing this was developed by Fischer and Rosanoff around 1900. Fischer first developed a method for drawing carbohydrates in two-dimensions, and a convention with respect to orientation, so as to indicate their three dimensional structures, so-called Fischer projections (see below).

WebConverting Fischer Projections into Haworth Projections. 1. Identify the hydroxyl group which is cyclizing onto the carbonyl group. This hydroxy will become the ring oxygen in the hemiacetal or hemiketal form of the carbohydrate. For D-glucose, it is the C5 hydroxyl in the pyranose form; for D-ribose, it is the C4-hydroxyl for the furanose form. 2. WebFischer Projections provide aid in visualizing chirality as well as where substituents are oriented within space which is why their application can be useful to many. Chirality from …
