Glucose and fructose have the same formula: c6h12o6 glucose is the sugar with the highest concentration in the bloodstream fructose is found in fruit and honey use the fischer projections in the figure of common monosaccharides to explain the difference between the structures of these compounds. 2 if one group of the fischer projection is held steady, the other groups can be rotated either clockwise or d-glucose d-fructose 1 1 2. Structural biochemistry/carbohydrates/monosaccharides monosaccharides are often represented by a fischer projection examples of ketohexose are fructose.

While organic chemists prefer to use the dashed/solid wedge convention to show stereochemistry, biochemists often use drawings called fischer projections. The d and l families of sugarsfischer projections fischer projections show the molecule in its non-cyclic form and indicates whether it is d and fructose.

If you are talking about the straight chain forms, they are stereoisomers that are enantiomers the fischer projections of d- and l-fructose are: are they anomers.
D-glucose is an aldehyde with the carbonyl group on carbon 1 d-fructose is a ketone with the carbonyl group on carbon 2. The fischer projection, points down in the haworth projection, and is axial in the chair conformation in a β monosaccharide, the –oh group attached to the anomeric carbon is on the left side of the fischer projection, points up in the haworth projection, and is equatorial in the chair conformation.
