What is Fischer projections and Haworth projections of carbohydrates?
The 3D arrangement of atoms in carbohydrates is depicted using Fischer and Haworth projections, respectively. They are also employed to contrast various carbs.
Fischer projection: The carbohydrate is seen in a Fischer projection as an open chain structure rather than a cyclical one. The main chain of carbon atoms in the carbohydrate molecule is joined vertically, while the horizontal bonds between hydrogen atoms and hydroxyl groups.
Haworth projection: In contrast to a Fischer projection, a Haworth projection depicts the carbohydrate in its cyclical form. This is especially helpful for sugars with rings in their molecules.
