Here the … WebFischer Projections and the D/L Notation: The first system for doing this was developed by Fischer and Rosanoff around 1900. Fischer first developed a method for drawing carbohydrates in two-dimensions, and a convention with respect to orientation, so as to indicate their three dimensional structures, so-called Fischer projections (see below).

WebFischer knew: - (+)-glucose is an aldohexose. - Therefore, there are 4 stereocenters and 24 = 16 stereoisomers (8 D-sugars and 8 L-sugars) - At this time could not determine the actual configuration (D or L) of sugars - Fischer arbitrarily assigned D-glyceraldehyde the following structure. - In 1951 Fischer was shown to have guessed correctly. WebFor glyceraldehyde, the d-form is an (R)-enantiomer while the l form is an (S)-enantiomer. Monosaccharides with a larger number of carbons may have more asymmetric carbons but they can be conventionally derived from glyceraldehyde (or dihydroxyacetone) by including more units in the carbon chain between the CH O group and the lowest unit ...
