Fischer projection is a  2-D (two-dimensional) representation of 3-D (three-dimensional) organic molecules on a flat surface (for example, on a leaf of paper). This notation system was devised by the German chemist Hermann Emil Fischer, who also determined the structures of huge amount of sugar molecules. Using Fischer projection method, chemical bonds of particular 3-D molecule are written only vertically and horizontally. Bonds which are written horizontally on the flat surface signify bonds which are in front of the flat surface in terms of three dimensions. On the contrary, bonds drawn vertically indicate bonds pointed beyond the flat surface considering three dimensions[1].
