Figure 02: Chemical Structure of Mannitol
Mannitol is an isomer of sorbitol. These two sugar alcohols differ from each other according to the orientation of the hydroxyl group that is attached to the second carbon atom of the sugar molecule.
We can obtain mannitol via the reduction of mannose sugar. However, the industrial-scale synthesis of mannitol is via the hydrogenation of fructose. Moreover, some organisms produce mannitol as a source of energy, e.g. bacteria, fungi, algae, lichens, etc. In addition, we can directly extract mannitol from its natural sources such as seaweed.
