Illustrated Glossary of Organic Chemistry

Fischer projection: A method of representing molecular structure, often for an acyclic carbohydrate. The meeting of two perpendicular lines indicates a stereocenter. Vertical lines at the stereocenter indicate groups that are pointing away from the viewer, as if on a dashed wedge. Horizontal lines indicate groups that are pointing towards the viewer, as if on a solid wedge. If the molecule represented by the Fischer projection is a carbohydrate, the projection is frequently drawn so the the carbonyl is as close to the top of the drawing as possible.
