WebQ: Complete the following table by providing the Fischer and Haworth Projections of the given sugars.… A: Fischer projection is a three-dimensional representation of sugar molecules in an open-chain form.… WebHaworth projection is different from the Newman in that it shows the bond between the front and back carbons. So, it is not looking directly through the bond, but rather at a slightly tilted angle: After this, we can now project the Haworth into bond-line and place the groups according to their arrangement:

How do I decide … WebApr 8, 2024 · Both Fischer projection and Haworth projections are standard methods of illustrating the stereochemistry of carbohydrates. However, a Haworth projection differs from a Fischer projection as the former is used to represent carbohydrates in their cyclical form. In contrast, the latter is used to depict sugars in their long-chain form.
