WebFischer 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 ambiguous and easily confused with other types of drawing. WebFischer Projections are abbreviated structural forms that allow one to convey valuable stereochemical information to a chemist (or biochemist) without them having to draw a more detailed 3D structural representation of the molecule.

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). diagram of a sprayerWebOrganic Chemistry Newman Projections When atoms in organic molecules connect via single bonds, you can have a free rotation around those single bonds.
