We can find sorbitol as a naturally occurring compound; e.g. in apple, pears, peaches, etc. We mostly obtain sorbitol from potato starch. Some organisms produce mannitol as a source of energy, e.g. bacteria, fungi, algae, lichens, etc.
Below infographic tabulates the differences between sorbitol and mannitol.
Summary – Sorbitol vs Mannitol
Sorbitol and mannitol are structural isomers. The key difference between sorbitol and mannitol is that the hydroxyl group at the second carbon atom of sorbitol Fischer projection is coming out of the plane, whereas in mannitol, the hydroxyl group at the second carbon atom of mannitol is going behind the plane in its Fischer projection.
