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. WebJan 23, 2024 · Introduction. The Fischer Projection consists of both horizontal and vertical lines, where the horizontal lines represent the atoms that are pointed toward the viewer while the vertical line represents atoms that are pointed away from the viewer. The point of intersection between the horizontal and vertical lines represents the central carbon.

WebWhile Fischer projections are used for sugars in their open-chain form, Haworth projections are often used to depict sugars in their cyclic forms. The betadiastereomer of the cyclic form of glucose is shown below in three different depictions, with the Haworth projection in the middle.

WebNachdem du also die Fischer-Projektion eines Moleküls erstellt hast, ist es vergleichsweise einfach, daraus die Haworth-Projektion zu entwickeln. Wichtigster Schritt dafür ist der Ringschluss. Oftmals ist im ersten Moment nicht ersichtlich, wo sich der Ring bildet. Bei der zuständigen Reaktion handelt es sich jedoch um eine Halbacetal-Bildung.
