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. A Haworth projection approximates the shapes of the actual molecules better for furanoses —which are in reality nearly planar—than for pyranoses that exist in ...
Sir Walter Norman Haworth FRS [1] (19 March 1883 [2] – 19 March 1950) was a British chemist best known for his groundbreaking work on ascorbic acid while working at the University of Birmingham. He received the 1937 Nobel Prize in Chemistry "for his investigations on carbohydrates and vitamin C".

When a glucopyranose molecule is drawn in the Haworth projection, the designation "α-" means that the hydroxyl group attached to C-1 and the −CH 2 OH group at C-5 lies on opposite sides of the ring's plane (a trans arrangement), while "β-" means that they are on the same side of the plane (a cis arrangement).
Different projections of α-D-glucopyranose. 1 = Fischer projection with C-1 at the top of the anomeric centre. C-5 is the anomeric reference atom. 2, 3 = Haworth projections.
The highest numbered chiral carbon (typically to the left of the oxygen in a Haworth projection) determines whether or not the structure has a d-configuration or L-configuration. In an l -configuration furanose, the substituent on the highest numbered chiral carbon is pointed downwards out of the plane, and in a D -configuration furanose, the ...
