Question

Harworth and fischer production structure of glucose

Answer 1

Explanation:

The Fischer projection was devised by German chemist Emil Fischer in 1891, who was the winner of the Nobel Prize in Chemistry in 1902. In a Fischer projection the carbohydrate is shown in its open chain form, rather than a cyclical one. Carbon atoms in the main chain of the carbohydrate molecule are connected vertically, whilst hydrogen atoms and hydroxyl groups are bonded horizontally. The horizontal lines illustrate the bonds which come out of the page, whereas the vertical lines show bonds that are in the page. Carbon atoms may or may not be shown in a Fischer projection.

Answer 2

Answer:

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