Key Differences
Mannose is a type of monosaccharide, or simple sugar, that plays a vital role in human metabolism, particularly in the glycosylation of certain proteins. On the other hand, mannitol is a sugar alcohol derived from mannose, commonly used as a sweetener in foods and as a medication.
Mannose is naturally occurring in many fruits and vegetables and is important for the health of the urinary tract. Whereas, mannitol, due to its ability to retain moisture and increase sweetness without impacting blood sugar levels significantly, is used in diabetic food products.
Mannose can be metabolized by the body and has been studied for its potential to aid in the management of diabetes. Conversely, mannitol is not metabolized in the same way and is often used in medical settings as a diuretic and to reduce high intracranial pressure.
In dietary supplements, mannose is often marketed for its purported benefits to immune system health. Mannitol, on the other hand, is utilized in pharmaceutical formulations to improve the stability and absorption of drugs.
Mannose is crucial for the biosynthesis of glycoproteins and glycolipids in human cells, which are important for cell communication and molecular stability. Mannitol, due to its properties, is also used as an excipient in chewable tablets and as a carrier in inhalation products.

Mannose
Mannose is a sugar monomer of the aldohexose series of carbohydrates. It is a C-2 epimer of glucose.
Mannitol
Mannitol is a type of sugar alcohol used as a sweetener and medication. It is used as a low calorie sweetener as it is poorly absorbed by the intestines.
Mannose
A monosaccharide, C6H12O6, obtained from mannan or by the oxidation of mannitol.
Mannitol
A white, crystalline, water-soluble, slightly sweet alcohol, C6H8(OH)6, found in plants, algae, and fungi. It is used in medicine, especially for its diuretic properties, and in foods as a sweetener and texturizer.
Mannose
(organic chemistry) A monosaccharide aldohexose found in manna and other legumes.
Mannitol
(organic compound) A polyhydroxy alcohol, an isomer of sorbitol, used as an artificial sweetener.
Mannitol
A white crystalline hexose (HO.CH2.(CHOH)4.CH2.OH) of a sweet taste obtained from a so-called manna, the dried sap of the flowering ash (Fraxinus ornus); - called also mannite, and hydroxy hexane. Cf. Dulcite. It is used in pharmacy as excipient and diluent for solids and liquids. It is also used as a food additive for anti-caking properties, or as a sweetener, and, illegally, to "cut" (dilute) illegal drugs such as cocaine or heroin.
