WebFischer/Haworth Diagrams. A It can be difficult at first to classify carbohydrates by their chirality centers. This is because there can be many chirality centers in the carbon backbone. This concept is simply an extension of stereoisomerism from Chapter 3. We now take a look at what this looks like for carbohydrate examples. WebIn chemistry, the Fischer projection, devised by Emil Fischer in 1891, is a two-dimensional representation of a three-dimensional organic molecule by projection. Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry.
