Discuss the haworth and fischer projection structure of glucose and fructose.
Fischer projection of glucose and fructose
Fischer projection shows the sugars in their open-chain form, where the carbon atoms of the molecules are connected vertically by solid lines, while the C-H and C-O bonds are drawn horizontally. In this case, stereochemical information is conveyed by a simple rule of thumb; vertical bond point into the plane of the page, while horizontal bonds pointing out of the page.
Haworth projections on the other hand are used to depict the sugar molecules in their cyclic forms.
