FAQ

Frequently Asked Questions

Yes, they are different names for the same chemical compound (C6H14O6). 'Mannitol' is the standard modern term.

It can be extracted naturally from manna (sap of certain trees), algae, mushrooms, and some fruits. It is also produced industrially.

Its main uses are as a sweetener in sugar-free foods, a diuretic in medicine to reduce brain swelling, and an osmotic agent in industrial processes.

It's a highly specialized technical term. The synonym 'mannitol' is preferred in modern scientific and medical English, making 'mannite' sound dated.
