Organic Chemistry: Stereochemistry: Fischer Projections

WebFischer projections were originally developed by German chemist Emil Fischer for work on carbohydrate (sugar) chemistry. It's a way to quickly draw multiple sugars and compare them since it's easy to spot the asymmetric carbons on a Fischer projection. WebFischer projections are written as vertical and horizontal lines. The carbon backbone is the vertical line, and the other substituents are horizontal. We assume that the horizontal bonds are coming out towards you (↓). This convention makes it easier to draw and to assign configuration to the chiral centers (this structure is S). ...
