en.wikipedia.org/wiki/Fischer_projection

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.The use of Fischer projections in non-carbohydrates is discouraged, as such drawings are ...

L-Glucose: L-Glucose can rotate plane polarized light in anticlockwise direction. Fischer Projection. D-Glucose: The Fischer projection of D-Glucose has a –OH group on the left side of the main carbon chain whereas other –OH groups are on the right side.

Namely, when the molecule is drawn in the Fischer projection, the hydroxyls on C-2, C-4, and C-5 must be on the right side, while that on C-3 must be on the left side. The positions of those four hydroxyls are exactly reversed in the Fischer diagram of l-glucose.

The key difference between D and L glucose is that in D-glucose, three hydroxyl groups and one hydrogen group are in the right side whereas, in L-glucose, the three hydroxyl groups and one hydrogen group are in the left side.. The “D” and “L” letter indication in the names of D-glucose and L-glucose are used to distinguish the structural differences in the glucose molecule.

If your sugar was D, then the carbon #6 is going to be looking “up” (down for the L sugar) The “right” groups on carbons 2, 3, and 4 in the Fischer projection go onto the “bottom” positions in Haworth; The “left” groups on carbons 2, 3, and 4 in the Fischer projection go onto the “up” positions in Haworth

It is a 2D structure and is a linear structure. Figure 1: Fischer Projection for D and L Glucose This is a 3D representation of the molecule and it shows the cyclic structure of the molecule. The cycle is formed through the formation of a bridge through the oxygen atom of aldehyde group. Figure 2: The Haworth Projection of D and L Glucose.

The notations D and L are used to describe the configuration of carbohydrates and amino acids. In a Fischer projection of a monosaccharide, the carbonyl group is always placed on top ( in the case of aldoses) or as close to the top as possible ( in case of ketoses). The mirror image of a D-sugar is an L-sugar.

D-Glucose D-Fructose 1 1 2 Carbohydrates and amino acids are designated as D- or L- according to the stereochemistry of the highest numbered carbon in the Fischer projection. If the hydroxyl group (or amino group for amino acids) is pointing to the right in the Fischer Projection, the sugar (or amino acid) is designated as D. If the
