Fischer Projection
A Fischer Projection is a two-dimensional representation of a three-dimensional organic molecule, primarily used for depicting carbohydrates and amino acids. In this projection, the molecule is drawn with vertical and horizontal lines, where vertical lines represent bonds that extend away from the viewer, and horizontal lines represent bonds that come toward the viewer. This format helps visualize the stereochemistry of the molecule, particularly the arrangement of substituents around chiral centers.
The Fischer Projection is named after the German chemist Emil Fischer, who developed this method in the late 19th century. It is particularly useful for illustrating the configuration of sugars, such as glucose and fructose, and amino acids, allowing chemists to easily identify their stereoisomers and understand their chemical behavior.
