WebConverting Fischer Projections into Haworth Projections. 1. Identify the hydroxyl group which is cyclizing onto the carbonyl group. This hydroxy will become the ring oxygen in the hemiacetal or hemiketal form of the carbohydrate. For D-glucose, it is the C5 hydroxyl in the pyranose form; for D-ribose, it is the C4-hydroxyl for the furanose form. 2.

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 … See more Now try a more challenging one. Starting with the structure of L-galactose, draw the Haworth as a β-pyranose.

WebApr 27, 2015 · To convert the Haworth projection to a Fischer projection, you mentally cleave the C-O bond and orient the new chain with C-1 at the top. If the CH2OH group is on the top in the Haworth structure, the OH group on C-5 is on the right. If the CH2OH group is on the bottom in the Haworth structure (an L sugar), the OH group on C-5 is on the left.
