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 ...
Allulose, also known by its systematic name D-ribo-2-hexulose as well as by the name D-psicose, is a monosaccharide and a ketohexose. [ 2 ] [ 11 ] It is a C3 epimer of fructose . [ 2 ] Fructose can be converted to allulose by the enzymes D -tagatose 3-epimerase ( EC 5.1.3.31 ) and/or D -psicose 3-epimerase ( EC 5.1.3.30 ), which has allowed for ...
Haworth Projection of β-D-glucopyranose Hermann Emil Fischer won the Nobel Prize in Chemistry (1902) for his work in determining the structure of the D - aldohexoses . [ 1 ] However, the linear, free-aldehyde structures that Fischer proposed represent a very minor percentage of the forms that hexose sugars adopt in solution.

Haworth projection of the chitin molecule. A close-up of the wing of a leafhopper; the wing is composed of chitin. A cicada emerges from its nymphal exoskeleton; the shed exoskeleton is mostly modified chitin but the wings and much of the adult body are still unsclerotized chitin at this stage

Altrose is an aldohexose sugar. D-Altrose is an unnatural monosaccharide.It is soluble in water and practically insoluble in methanol.However, L-altrose has been isolated from strains of the bacterium Butyrivibrio fibrisolvens.
