Fischer and newman projections

WebThe Newman projection formula is the planar projection formula of the sawhorse formula. Newman projection is similar to the sawhorse projection but represents the spatial arrangements of all the groups on the two carbon atoms. Here, a molecule is viewed along the axis of a carbon-carbon bond. WebFischer projections are a way to represent three-dimensional molecules in two dimensions. By following specific rules for drawing these projections, one can depict complex carbohydrates such as glucose and fructose in a way that conveys their structural information. Created by Jay.
