| mannite | 1. <chemistry> A white crystalline substance of a sweet taste obtained from a so-called manna, the dried sap of the flowering ash (Fraxinus ornus); called also mannitol, and hydroxy hexane. Cf. Dulcite. (MI11) HO.CH2.(CHOH)4.CH2.OH = D-mannitol; manna sugar; cordycepic acid; Diosmol; Mannicol; Mannidex; Osmiktrol; Osmosal. Used in pharmacy as excipient and diluent for solids and liquids. Used as a food additive for anti-caking properties, or as a sweetener. Also used to "cut" (dilute) illegal drugs such as cocaine or heroin. ("excipient" use) 2. <botany> A sweet white efflorescence from dried fronds of kelp, especially from those of the Laminaria saccharina, or devil's apron. Origin: Cf. F. Mannite.

| mannitol - mannose 1-oxidoreductase | <enzyme> Isolated from celeriae root tips; catalyses the nad-dependent oxidation of mannitol to mannose not to fructose; strongly inhibited by NADH and sensitive to alterations of nad-NADH ratio. Do not confuse with mannitol dehydrogenase (EC 1.1.1.67) which is a 2-oxidoreductase which converts mannitol to fructose Registry number: EC 1.1.1.- Synonym: mannitol 1-dehydrogenase (26 Jun 1999) |

| mannitol hexanitrate | An explosive compound formed by the nitration of mannitol; when diluted with carbohydrate substances (one part of mannitol hexanitrate to nine or more parts of carbohydrate) it is not explosive, and is used as a vasodilator and hypotensive agent; it is slower in action than nitroglycerin. Synonym: nitromannitol. (05 Mar 2000) |
