WebApr 8, 2024 · Definition. Fischer projection is defined as the method of presenting three-dimensional organic molecules in two-dimensional structures on a two-dimensional plane such as a paper. Horizons and vertical lines are used to represent the bonds and the intersection of a horizontal and a vertical line represents the central carbon atom. Chirality is an asymmetric quality that is relevant in many fields of science. The word chirality comes from the Greek (kheir), which means “hand,” a common chiral item.
