WebNachdem du also die Fischer-Projektion eines Moleküls erstellt hast, ist es vergleichsweise einfach, daraus die Haworth-Projektion zu entwickeln. Wichtigster Schritt dafür ist der Ringschluss. Oftmals ist im ersten Moment nicht ersichtlich, wo sich der Ring bildet. Bei der zuständigen Reaktion handelt es sich jedoch um eine Halbacetal-Bildung. WebC Because carbohydrates can have cyclic hemiacetal structures, the next problem is how to change from the Fischer projection to the cyclic Haworth projection. This projection is a view in which the ring is drawn as planar. The rings may be 5- or 6-membered, for furanose or pyranose, on which the substituents either point above or below the ...
