D-Galactitol is one of the toxic compounds produced by the disease galactosemia. Accumulation of high levels of D-galactitol causes the formation of cataracts. A Fischer projection for D-galactitol is shown at right:

(a) Draw a three-dimensional structure for D-galactitol.

(b) Draw the mirror image of D-galactitol and write its Fischer projection formula.

(c) What is the stereochemical relationship between D-galactitol and its mirror image?
