WebApr 8, 2024 · A Fischer projection is not an accurate representation of the actual 3D configuration of a chemical molecule. It is an altered version of the molecule, ideally … 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 … 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 … See more Now try a more challenging one. Starting with the structure of L-galactose, draw the Haworth as a β-pyranose. See more Mannose is a hexose where the configuration at C2 is flipped relative to glucose. Using the shortcuts above, try converting it to a Haworth as an α-pyranose. (answer at … See more
