-
mannitol oxidase plays an active role in the utilization of dietary mannitol

D-mannitol + O2
mannose + H2O2
-
because of high mannitol content of many plants, the herbivorous diet of terrestrial snails, and the association of mannitol oxidase with their digestive tract, the snail enzyme may represent a unique nutritional adaption of these and possibly other herbivorous molluscs
