Definition of the noun Mannitol
What does Mannitol mean as a name of something?
noun - plural: mannitols
- [organic compound] a polyhydroxy alcohol, an isomer of sorbitol, used as an artificial sweetener
- synonym: E421 when used as a sweetener
- Mannitol is a white, crystalline solid that looks and tastes sweet like sucrose. It was originally isolated from the secretions of the flowering ash and called manna after its resemblance to the Biblical food. In plants it is used to induce osmotic stress. Mannitol has several industrial uses, but is mainly used to produce tablets of medicine. Its fetal safety is "C" in Briggs' Reference Guide to Fetal and Neonatal Risk. Mannitol is classified as a sugar alcohol; that is, it is derived from a sugar by reduction. Other sugar alcohols include xylitol and sorbitol. Mannitol and sorbitol are isomers, the only difference being the orientation of the hydroxyl group on carbon 2.
- also known as Cordycepate, Cordycepic acid, Diosmol, Hexahydroxyhexane, Hexanhexol, Hexitol, Invenex, Isotol, MAN, MTL, Manicol, Maniton s, Manna sugar, Mannazucker, Mannidex, Mannigen, Mannistol, Mannit, Mannit p, Mannite, Marine crystal, Mushroom sugar, Osmitrol, Osmofundin, Osmosal, Resectisol
- Mannitol: A naturally occurring alcohol found in fruits and vegetables and used as an osmotic diuretic. Mannitol is freely filtered by the glomerulus and poorly reabsorbed from the renal tubule, thereby causing an increase in osmolarity of the glomerular filtrate. An increase in osmolarity limits tubular reabsorption of water and inhibits the renal tubular reabsorption of sodium, chloride, and other solutes, thereby promoting diuresis. In addition, mannitol elevates blood plasma osmolarity, resulting in enhanced flow of water from tissues into interstitial fluid and plasma.

Mannitol is an osmoprotectant and also serves as a storage compound and a redox agent. Mannitol degradation produces, in its initial stage, NADH and its oxidation in mitochondria yields up to three molecules of ATP (Stoop et al., 1996).
