WebIn a standard Haworth projection of the cyclohexane structures of hexoses, D-carbohydrates have the terminal carbon (typically -CH2OH) pointing up. Examples of D and L carbohydrates The Fischer projections of D and L glyceraldehyde shown above illustrate the relationship between D and L and the stereochemistry of the penultimate carbon. WebIn a Fischer projection, if the substituent off the anomeric centre is on the same side as the oxygen of the configurational (D- or L-) carbon, then it is the α--anomer. If it is directed in the opposite direction it is the β-anomer. Example 1. Fischer projections and Haworth conformational projections of L-arabinose. Example 2.
