galactitol
Sign in to saveAlso known as D-galactitol, D-Dulcitol, Melampyrin, Melampyrit, Euonymit, (2R,3S,4R,5S)-hexane-1,2,3,4,5,6-hexol, L-galactitol, Ambap5938
Galactitol (dulcitol) is a sugar alcohol, the reduction product of galactose. It has a slightly sweet taste. In people with galactokinase deficiency, a form of galactosemia, excess dulcitol forms in the lens of the eye leading to cataracts.

Galactitol (dulcitol) is a sugar alcohol, the reduction product of galactose. It has a slightly sweet taste. In people with galactokinase deficiency, a form of galactosemia, excess dulcitol forms in the lens of the eye leading to cataracts.
Galactitol is produced from galactose in a reaction catalyzed by aldose reductase.
