Drawing Haworth structures of sugars

Draw Haworth structures for the two possible isomers of D-altrose (Figure 1) and D-psicose (Figure 2).

Figure 1

Figure 1 The structure and stereochemical relationships of D-aldoses having three to six carbons. The configuration in each case is determined by the highest numbered asymmetric carbon.

Figure 2

Figure 2 The structure and stereochemical relationships of D-ketoses having three to six carbons. The configuration in each case is determined by the highest numbered asymmetric carbon.
