http://www.chem.ucla.edu/~harding/IGOC/R/ribose.html Web10. Haworth projection: Fischer representations are not as useful to visualize the ring form of CHOs. We use the Haworth projection to visualize the ring form, as a planar ring with OH groups above and below the ring. Does not represent true shape of rings, they are puckered. For pyranose rings, the two conformations are the chair and the boat.
WebJan 23, 2024 · Haworth projections don't reflect the real shape of the ring. For example, in a six-membered ring, the atoms in the ring adopt a zig-zag, up-and-down pattern in order to optimize bond angles. The chair drawing shows that relationship, but in a Haworth projection, the ring is drawn as though it were flat. ...
