Fischer projection vs haworth projection
WebJun 3, 2024 · In fact the Haworth projection pre-dates (1929) the chair depiction of cyclohexane (1943) and represented a vast improvement from the most common depiction of cyclic sugars at that time: the bloodyawful cyclic Fischer projection: The Haworth projection didn’t go away with the advent of the cyclohexane chair, however. Here’s why. WebApr 27, 2015 · The groups below the plane of the ring are on the right hand side of a Fischer projection. 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.
