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 ...

English: Haworth projection of chitin — a polymer consisting of N-acetyl-D-glucosamine monomers. Bent bonds follow the recommendations given in IUPAC Recommendations on Graphical Representation Standards for Chemical Structure Diagrams, 2008. Created with ChemDoodle 7.0.2 and Adobe Illustrator CC 2015.
Equal-area projections, especially the Albers Equal-Area Conic, and equidistant projections which have correct scale along many lines appear in the National Atlas. Other projections, such as the Miller Cylindrical and the Van der Grinten, are chosen occasionally for convenience, sometimes making use of existing base maps prepared by others.

English: Haworth projection of hyaluronan — a polymer consisting of D-glucuronic acid and N-acetyl-D-glucosamine linked via alternating β-(1→4) and β-(1→3) glycosidic bonds. Created with ChemDoodle 8.1.0 and Adobe Illustrator CC 2015.
In honour of the compound's antiscorbutic properties, Haworth and Szent-Györgyi now proposed the new name of "a-scorbic acid" for the molecule, with L-ascorbic acid as its formal chemical name. During World War II, he was a member of the MAUD Committee which oversaw research on the British atomic bomb project. [2]
