Fischer projection of d-glucose
WebWe have already talked about Fischer projection formulas for representing the cyclic forms of D-glucose. However, Haworth thought that these structures were awkward. He developed the hexagonal representations which resembled the heterocyclic pyran containing five carbon and one oxygen in the ring. WebThe Fischer projection of D-glucose is given in Figure 6.4. 2. Glucose is a D sugar because the OH group on the fifth carbon atom (the chiral center farthest from the carbonyl group) is on the right. In fact, all the OH groups except …

WebD-Glucose can be represented with a Fischer projection (a) or three dimensionally (b). By reacting the OH group on the fifth carbon atom with the aldehyde group, the cyclic monosaccharide (c) is produced.
