Sorbitol Dehydrogenase, Sheep (EC 1.1.1.14), is an enzyme involved in carbohydrate metabolism that converts sorbitol, the sugar alcohol form of glucose, into fructose. In conjunction with aldose reductase, Sorbitol Dehydrogenase enables the body to use glucose to produce fructose without ATP consumption. This enzyme uses NAD+ as a cofactor, with zinc ions also participating in the catalytic process.
