WebMay 8, 2024 · Figure 1: Cyclization of D-Glucose. D-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 α- D-glucopyranose (c) is produced. In β -D-glucopyranose, the OH group on the anomeric carbon points up. WebAug 6, 2016 · For D-erythose, carbon 4, (the last carbon), connects to the O which connects to Carbon 1. However, for D-glucose, carbon 5 (the 2nd last carbon) attaches to the O …

Having walked through the process the long way, let’s try to come up with a shortcut for this process. Compare the Fischer projection of D-glucose to the final Haworth: 1. C2–OH is on the right side of the Fischer and ends up on the bottomof the Haworth. 2. C3–OH is on theleft side of the Fischer and ends … See more Here’s a relatively common problem in the realm of sugar chemistry: “Convert this (sugar) from the Fischer projection to a cyclic pyranose form as a Haworth projection.” (the … See more In our example the C5-OH was on the right side of the Fischer, which made it (by definition) a D-sugar. We saw that C6 (the CH2OH) ended up on the top of the Haworth, so we can make a generalization: 1. for … See more Now try a more challenging one.
