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. WebJul 25, 2015 · Recall that the Newman Projection is a method of analyzing a molecule that has pre rotation between two sp3 carbons. So that you have for example carbon 2 in a molecule, here but carbon 3 is hiding behind carbon 2. For this specific molecule both carbons 2 and carbons 3 are chiral. So if we convert it to a Fischer Projection we're …
