Drawing Fischer Projections
Drawing Fischer Projections - 67k views 8 years ago. Before getting to drawing its fischer projection, lets number the carbons in any order (no iupac rules needed). A fischer projection or fischer projection formula is a convention used to depict a stereoformula in two dimension without destroying the stereochemical information, i.e., absolute configuration, at chiral. Web how to draw fischer projections. Web sugars can be drawn in the straight chain form as either fisher projections or perspective structural formulas. Look closely at the structure and figure out which chain is the longest. By following specific rules for drawing these projections, one can depict complex carbohydrates such as glucose and fructose in a way that conveys their structural information. In a fischer projection drawing, the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines. The horizontal bonds are seen as wedges and the vertical bonds are seen as dashed lines as shown below in the example below for glyceraldehyde. The two horizontal bonds are directed toward the viewer (forward of the stereogenic carbon). Remember, numbering carbons will always be helpful no matter what you need to do with an organic structure. How do we assign r/s when the priority #4 group is in the front?
