'''Sorbitol''', also known as '''glucitol''', is a ] the body metabolises slowly. It is obtained by ] of ] taking the ] group to an additional ] group hence the name ''sugar alcohol''.

Sorbitol is an ] often used in diet ]s (including diet drinks). It is called a nutritive sweetener because it provides 2.6 ]s (11 ]s) per ] versus the 4 calories (17 kJ) of ] and ]. Sorbitol also occurs naturally in many ]s.

Sorbitol is produced naturally by the body, yet sorbitol is poorly ] by the body. Too much sorbitol in ]s can cause damage.

] ] and ] may be related to excess sorbitol in the cells of the ]s and ]s. The source of this sorbitol in diabetics is excess ], which goes through the ]. Ingesting large amounts of sorbitol can lead to some abdominal pain, gas, and mild to severe ]. Sorbitol can also aggravate ] and ].

Sorbitol is often used in modern ] as a ] and ]. Some transparent ]s can only be made with sorbitol as it has a ] sufficiently high for transparent formulations. It is also used as a ] in some ]s.

Sorbitol is used as a ] additive (mixed with ] and sodium poly]s) in the manufacture of ], a highly ], uncooked ] paste most commonly produced from ] (or walleye) ] (Theragra chalcogramma).

Sorbitol is identified as a potential key chemical intermediate <ref>''Production of Liquid Hydrocarbons from Biomass '' Jürgen O. Metzger ] Volume 45, Issue 5 , Pages 696 - 698 '''2005''' </ref> from ] resources. Complete reduction of sorbitol opens the way to ]s such as ] which can be used as a ]. Sorbitol itself provides much of the hydrogen required for the transformation.

The above ] is ] and 1.5 ] of sorbitol generates 1 mole of hexane. When hydrogen is co-fed no ] production takes place. The advantage of hexane as a biofuel over well established other biofuels such as ] is that hexane easily separates from water. In fact, the energy required to distill ethanol from water in the bio-ethanol production process eliminates much of the energy advantages.
