In chemistry, the Fischer projection, devised by Emil Fischer in 1891, is a two-dimensional representation of a three-dimensional organic molecule by projection. Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry .
1 = Fischer projection with C-1 at the top of the anomeric centre. C-5 is the anomeric reference atom. 2, 3 = Haworth projections. 4 = Mills projection.
Hermann Emil Louis Fischer FRS FRSE FCS (German pronunciation: [ˈeːmiːl ˈfɪʃɐ] ⓘ; 9 October 1852 – 15 July 1919) was a German chemist and 1902 recipient of the Nobel Prize in Chemistry. He discovered the Fischer esterification. He also developed the Fischer projection, a symbolic way of drawing asymmetric carbon atoms. He also ...
In chemistry, a Haworth projection is a common way of writing a structural formula to represent the cyclic structure of monosaccharides with a simple three-dimensional perspective. Haworth projection approximate the shapes of the actual molecules better for furanoses —which are in reality nearly planar—than for pyranoses that exist in ...
The Fischer projection is a systematic way of drawing the skeletal formula of an acyclic monosaccharide so that the handedness of each chiral carbon is well specified. Each stereoisomer of a simple open-chain monosaccharide can be identified by the positions (right or left) in the Fischer diagram of the chiral hydroxyls (the hydroxyls attached ...

Two important hexoses, in the Fischer projection. In chemistry , a hexose is a monosaccharide (simple sugar) with six carbon atoms. [ 1 ] [ 2 ] The chemical formula for all hexoses is C 6 H 12 O 6 , and their molecular weight is 180.156 g/mol. [ 3 ]
