Fischer projection

Jump to: navigation, search

The Fischer projection is a two-dimensional representation of a linear monosaccharide showing the stereochemistry. The figure below shows - from left to right - (a) a wedge-and-dashes representation of glucose in a relaxed conformation, (b) glucose in a conformation where the carbon chain is in an all-syn conformation, (c) with the carbon chain on the vertical axis and (d) the Fischer projection. This insightful series of images is from https://commons.wikimedia.org/wiki/File:Fischer_projection_-_projection_of_D-glucose.png

The 3D image shows glucose in the all-syn conformation. You can rationalize the Fischer projection by centering on each carbon atom, keeping carbon 1 (the aldehyde function) on top and the carbon chain curved backwards. The coordinates of glucose are from https://sites.science.oregonstate.edu/~gablek/CH334/Chapter5/fischer.htm.
