The positions of those four hydroxyls are exactly reversed in the Fischer diagram of l-glucose. d - and l-glucose are two of the 16 possible aldohexoses; the other 14 are allose, altrose, galactose, gulose, idose, mannose, and talose, each with two enantiomers, “ d-” and “ l-”.

D-glucose is the main energy source in most of the living organisms. However, L-Glucose is a low-calorie sweetener that is a good suggestion for diabetes patients. Summary – D vs L Glucose. The “D” and “L” letter indication in the names of D-glucose and L-glucose are useful to distinguish the structural differences in the glucose ...

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.

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 ...

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

L-(−)-Glucose is an enantiomer of the more common D-glucose. L-Glucose cannot be used by cells as an energy source because it cannot be phosphorylated by hexokinase. Application L-(-)-Glucose has been used in phospho-buffered saline (PBS) solution to induce metabolic responses in Saccharomyces cerevisiae.

This was a great research program in the 1980’s. The thought was that if they could produce the L glucose in large amounts it would be the answer the need for sugar that would not cause you to gain weight. The only problem was that it is very rare...

Thanks for the A2A! Below I’ve attached a quick figure to summarize the answer to your question. The top two are Fischer projections. Fischer projections have the aldehyde at the top and pointing upwards and to the left. You’ll note that the rest ...
