WebJan 23, 2024 · As part of his Nobel Prize-winning research on carbohydrates, the great German chemist Emil Fischer, devised a simple notation that is still widely used. In a Fischer projection drawing, the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines. 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 …
WebThe relationship between a Fischer projection and a Haworth projection is that the group on the right in a Fischer projection is down in the Haworth projection. The group on the left in a Fischer projection is up in a Haworth projection. For D-sugars, the terminal -CH 2 OH group is always up in Haworth projections, whereas for L-sugars the ...
