Identification
Name:Mannitol
DescriptionMannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity. Chemically, mannitol is an alcohol and a sugar, or a polyol; it is similar to xylitol or sorbitol. However, mannitol has a tendency to lose a hydrogen ion in aqueous solutions, which causes the solution to become acidic. For this, it is not uncommon to add a substance to adjust its pH, such as sodium bicarbonate.; Mannitol is a non-permeating molecule i.e. it cannot cross biological membranes.; Mannitol is a sorbitol isomer.

Protein EIIB N(pi)-phospho-L-histidine/cysteine + sugar = protein EIIB + sugar phosphate.
General function:
Involved in sugar:hydrogen symporter activity
Specific function:
The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in mannitol transport
