WebQuestion: 1. draw the haworth perspective formulas for disaccharides containing two glucose molecules in an (alpha 1 -> 4 ) linkage, in an ( beta 1->4) linkage and a (alpha 1->6)linkage 2. draw fischer projection and haworth perspective representations of the following molecules. use the L or D form for fisher and alpha or beta form for haworth a. WebNov 9, 2016 · In a Haworth projection, the hexagonic shape of the ring already implies the direction of two bonds. The two bonds on the ring are always ‘bent ring-inwards’ when viewed from the outside. Thus, the two perpendicular bonds (typically vertical) must ‘point away’ from the ring: in a forward direction for the front carbons of a ring and in ...
