WebNote that Fischer projections of carbohydrates are typically drawn with the longest chain oriented vertically and with the more highly oxidised C (the carbonyl group) at the top. Here we see the Fischer projections of the simplest carbohydrate, glyceraldehyde in its (S)-(-)- and (R)-(+)- forms: S-(-)-glyceraldehyde ... WebR and S configuration on Newman projections To determine the R and S configuration of a chiral carbon in Newman projections, we need to look through the bond such that the lowest priority group is pointing back. But first, one question – why would anyone need to determine R and S on a Newman projection, right?
