Application
May be used for washing spheroplasts and in isoelectric focusing to minimize endoosmotic flow in agarose gels. May be used to induce osmotic stress.
Sorbitol, a bacterial culture supplement, has been used for the preparation of selective plating media to culture Sorbitol-fermenting bacteria including strains of Escherichia coli and Yersinia enterocolitica. It has also been used as one of the ingredients to prepare Drosophila embryos for immunoelectron microscopy. It has also been used as an additive to glucuronoxylan as potential food packaging material.
Biochem/physiol Actions
D-Sorbitol is a sugar alcohol that is commonly used as a sugar substitute. It occurs naturally and is also produced synthetically from glucose. The food industry uses D-sorbitol as an additive in the form of a sweetener, humectant, emulsifier, thickener, or dietary supplement. D-Sorbitol has also been found in cosmetics, paper, and pharmaceuticals. Naturally, D-sorbitol occurs widely in plants via photosynthesis, ranging from algae to higher order fruits of the family Rosaceae.
Sorbitol is a slowly metabolized sugar alcohol produced by reduction of glucose. In the polyol pathway, sorbitol is further oxidized to fructose by sorbitol dehydrogenase. Sorbitol does not diffuse easily across the cell membranes and may cause osmotic damage to the cells. The metabolism of sorbitol is most important in the pathology of diabetes related vascular complications.

Free films based on glucuronoxylan isolated from aspen wood were prepared by casting from aqueous solutions and drying in a controlled environment. Addition of xylitol or sorbitol facilitated film formation and thus examination of the material properties of these films.

Diabetes-specific microvascular disease is a leading cause of blindness, renal failure and nerve damage, and diabetes-accelerated atherosclerosis leads to increased risk of myocardial infarction, stroke and limb amputation. Four main molecular mechanisms have been implicated in glucose-mediated vascular damage. All

A pathway from glucose via sorbitol bypasses the control points of hexokinase and phosphofructokinase in glucose metabolism. It also may produce glycerol, linking the bypass to lipid synthesis. Utilization of this bypass is favored by a plentiful supply of glucose--hence

A promising new compound class for treating human malaria is the imidazolopiperazines (IZP) class. IZP compounds KAF156 (Ganaplacide) and GNF179 are effective against Plasmodium symptomatic asexual blood-stage infections, and are able to prevent transmission and block infection in animal models.
