'''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''. | |||
==Synthesis== | |||
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. | |||
<!-- linked from redirect ] --> | |||
Sorbitol may be synthesised via a glucose reduction reaction<ref>{{cite web|title=Reduction of Glucose|url=http://butane.chem.uiuc.edu/pshapley/GenChem2/B8/1.html|website=butane.chem.uiuc.edu|access-date=2017-10-03|archive-date=2017-09-25|archive-url=https://web.archive.org/web/20170925133922/http://butane.chem.uiuc.edu/pshapley/GenChem2/B8/1.html|url-status=dead}}</ref> in which the converted ] group is converted into a ] group. The reaction requires ] and is catalyzed by ]. Glucose reduction is the first step of the ] of ], and is implicated in multiple diabetic complications. | |||
<chem display="block">C6H12O6 + NADH + H+ -> C6H14O6 + NAD+</chem>The mechanism involves a ] residue in the active site of aldehyde reductase. The hydrogen atom on NADH is transferred to the electrophilic aldehyde carbon atom; electrons on the aldehyde carbon-oxygen double bond are transferred to the oxygen that abstracts the proton on tyrosine side chain to form the hydroxyl group. The role of aldehyde reductase tyrosine phenol group is to serve as a general acid to provide proton to the reduced aldehyde oxygen on glucose. | |||
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 ]. | |||
Glucose reduction is not the major ] pathway in a normal human body, where the ] is in the normal range. However, in diabetic patients whose blood glucose level is high, up to 1/3 of their glucose could go through the glucose reduction pathway. This will consume NADH and eventually leads to cell damage. | |||
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. | |||
==Uses== | |||
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). | |||
===Sweetener=== | |||
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. | |||
Sorbitol is a ], and when used in food it has the ] and ] 420. Sorbitol is about 60% as sweet as sucrose (table sugar).<ref>]</ref> | |||
Sorbitol is referred to as a nutritive sweetener because it provides some dietary energy. It is partly absorbed from the small intestine and metabolized in the body, and partly fermented in the large intestine. The fermentation produces ]s, ], ], and ], which are mostly absorbed and provide energy, but also ], ], and ] which do not provide energy. Even though the ] of sorbitol is higher than that of glucose (having two extra hydrogen atoms), the net energy contribution is between 2.5 and 3.4 ]s per ], versus the approximately 4 kilocalories (17 kilojoules) for carbohydrates.<ref>{{cite journal |last1=Tsuneyuki Oku and Sadako Nakamura |title=Digestion, absorption, fermentation, and metabolism of functional sugar substitutes and their available energy |journal=Pure Appl.

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. | |||

====Other medical applications==== | |||
"WASHINGTON - The Center for Science in the Public Interest today petitioned the Food and Drug Administration (FDA) to improve the existing warning label on processed foods that contain the sugar substitute sorbitol. Sorbitol is a sweet-tasting sugar alcohol used in many sugar-free or “dietetic” candies, cake mixes, syrups, and other foods, as well as in some medicines. It provides fewer calories than regular sugars, because it is poorly absorbed by the body. | |||
Sorbitol is used in bacterial culture media to distinguish the pathogenic ] from most other strains of '']'', because it is usually unable to ferment sorbitol, unlike 93% of known ''E. coli'' strains.<ref name=wells_1983_101>{{cite journal |vauthors=Wells JG, Davis BR, Wachsmuth IK, etal |title=Laboratory investigation of hemorrhagic colitis outbreaks associated with a rare Escherichia coli serotype|journal=Journal of Clinical Microbiology|volume=18|issue=3|pages=512–20| date=September 1983 |pmid=6355145|pmc=270845|doi=10.1128/JCM.18.3.512-520.1983|quote=The organism does not ferment sorbitol; whereas 93% of E. coli of human origin are sorbitol positive}}</ref> | |||

Studies over the past fifteen years have proven that sorbitol can cause gastrointestinal symptoms, ranging from mild discomfort to severe diarrhea, when adults consume between 10 and 50 grams of the additive. Children, because of their small size, may be affected by even smaller amounts. Currently, the FDA requires a laxative notice only on the few products that may lead to the consumption of 50 grams or more of sorbitol daily, though some companies voluntarily label additional products. | |||
Sorbitol is also used in the manufacture of ]s to store single doses of liquid medicines.<ref name="Catalent Softgel website">{{cite web|url=http://www.catalent.com/offerings/drug-delivery/drug-delivery-oral/softgel-technology|title=Home – Catalent|work=catalent.com|access-date=12 July 2015}}</ref> | |||
“The FDA should require a better label notice on sorbitol-containing products,” said Michael F. Jacobson, Ph.D., executive director of CSPI. “The FDA has known for years that sorbitol can cause severe diarrhea. It’s high time that the Agency required a strong label notice on all products that might cause problems.” | |||
===Health care, food, and cosmetic uses=== | |||
“Since even small amounts of sorbitol can cause gastrointestinal symptoms it is important for the FDA to inform the public of this potential problem,” said Dr. Jeffrey S. Hyams, Head, Department of Digestive Diseases and Nutrition, Connecticut Children’s Medical Center, and Professor of Pediatrics, Connecticut University School of Medicine. “I know of people who have undergone extensive medical testing for abdominal pain and diarrhea when the problem was simply that they were ingesting excessive amounts of sorbitol.” Dr. Hyams conducted a clinical study in which five of seven adults experienced gastrointestinal symptoms after ingesting 10 grams of sorbitol. | |||

Some products that contain more than 10 grams of sorbitol or similar sugar substitute per serving include: Brach’s Star Brites Fruity Candies, Life Savers Delites Hard Candy; Cumberland Packing Corp.’s Sweet ‘N Low Sugar Free, Low Fat Cake Mixes; Frutay Peppermint Drops; Cary’s Maple Syrup; Allen Wertz Simply Sugar Free Chocolate & Vanilla Caramels, Fruit Taffy Whips, and Coffee Toffee. | |||
Beyond its use as a sugar substitute in reduced-sugar foods, sorbitol is also used as a humectant in cookies and low-moisture foods like peanut butter and fruit preserves.<ref name=":0">{{cite book|title=Chemical and functional properties of food saccharides|date=2004|publisher=CRC Press|others=Tomasik, Piotr|isbn=9780203495728|location=Boca Raton|oclc=317752036}}</ref> In baking, it is also valuable because it acts as a ], and slows down the ] process.<ref name=":0" /> | |||
“With Halloween coming up, people should be concerned about well-meaning families giving candy to children that could end up giving them severe diarrhea,” said Dr. Ray Breitenbach. Dr. Breitenbach is a practicing family physician and retired United States Air Force Lt. Colonel Flight Surgeon who has written about the risks of eating sorbitol-containing candy. | |||
===Miscellaneous uses=== | |||
CSPI has petitioned the FDA to require foods containing one or more grams per serving of sorbitol or other sugar alcohol, such as mannitol, to carry a more informative notice. CSPI’s petition recommends that labels state: “NOTICE: This product contains sorbitol, which may cause diarrhea, bloating, and abdominal pain. Not suitable for consumption by children. To protect yourself, start by eating no more than one serving at a time.” | |||

Sorbitol (/ˈsɔː(r)bɪtɒl/), less commonly known as glucitol (/ˈɡluːsɪtɒl/), is a sugar alcohol with a sweet taste which the human body metabolizes slowly. It can be obtained by reduction of glucose, which changes the converted aldehyde group (−CHO) to a primary alcohol group (−CH2OH). Most sorbitol is made from potato starch, but it is also found in nature, for example in apples, pears, peaches, and prunes. It is converted to fructose by sorbitol-6-phosphate 2-dehydrogenase. Sorbitol is an isomer of mannitol, another sugar alcohol; the two differ only in the orientation of the hydroxyl group on carbon 2. While similar, the two sugar alcohols have very different sources in nature, melting points, and uses.
As an over-the-counter drug, sorbitol is used as a laxative to treat constipation.
Synthesis
Sorbitol may be synthesised via a glucose reduction reaction in which the converted aldehyde group is converted into a hydroxyl group. The reaction requires NADH and is catalyzed by aldose reductase. Glucose reduction is the first step of the polyol pathway of glucose metabolism, and is implicated in multiple diabetic complications.
The mechanism involves a tyrosine residue in the active site of aldehyde reductase. The hydrogen atom on NADH is transferred to the electrophilic aldehyde carbon atom; electrons on the aldehyde carbon-oxygen double bond are transferred to the oxygen that abstracts the proton on tyrosine side chain to form the hydroxyl group. The role of aldehyde reductase tyrosine phenol group is to serve as a general acid to provide proton to the reduced aldehyde oxygen on glucose.
Glucose reduction is not the major glucose metabolism pathway in a normal human body, where the glucose level is in the normal range. However, in diabetic patients whose blood glucose level is high, up to 1/3 of their glucose could go through the glucose reduction pathway. This will consume NADH and eventually leads to cell damage.
Uses
Sweetener
Sorbitol is a sugar substitute, and when used in food it has the INS number and E number 420. Sorbitol is about 60% as sweet as sucrose (table sugar).
Sorbitol is referred to as a nutritive sweetener because it provides some dietary energy. It is partly absorbed from the small intestine and metabolized in the body, and partly fermented in the large intestine. The fermentation produces short-chain fatty acids, acetic acid, propionic acid, and butyric acid, which are mostly absorbed and provide energy, but also carbon dioxide, methane, and hydrogen which do not provide energy. Even though the heat of combustion of sorbitol is higher than that of glucose (having two extra hydrogen atoms), the net energy contribution is between 2.5 and 3.4 kilocalories per gram, versus the approximately 4 kilocalories (17 kilojoules) for carbohydrates. It is often used in diet foods (including diet drinks and ice cream), mints, cough syrups, and sugar-free chewing gum. Most bacteria cannot use sorbitol for energy, but it can be slowly fermented in the mouth by Streptococcus mutans, a bacterium that causes tooth decay. In contrast, many other sugar alcohols such as isomalt and xylitol are considered non-acidogenic.
It also occurs naturally in many stone fruits and berries from trees of the genus Sorbus.
Medical applications
Laxative
As is the case with other sugar alcohols, foods containing sorbitol can cause gastrointestinal distress. Sorbitol can be used as a laxative when taken orally or as an enema. Sorbitol works as a laxative by drawing water into the large intestine, stimulating bowel movements. Sorbitol has been determined safe for use by the elderly, although it is not recommended without the advice of a physician.
Sorbitol is commonly used orally as a one-time dose of 30–150 millilitres (1.1–5.3 imp fl oz; 1.0–5.1 US fl oz) 70% solution. It may also be used as a one-time rectal enema.
Other medical applications
Sorbitol is used in bacterial culture media to distinguish the pathogenic Escherichia coli O157:H7 from most other strains of E. coli, because it is usually unable to ferment sorbitol, unlike 93% of known E. coli strains.
A treatment for hyperkalaemia (elevated blood potassium) uses sorbitol and the ion-exchange resin sodium polystyrene sulfonate (tradename Kayexalate). The resin exchanges sodium ions for potassium ions in the bowel, while sorbitol helps to eliminate it. In 2010, the U.S. FDA issued a warning of increased risk for gastrointestinal necrosis with this combination.
Sorbitol is also used in the manufacture of softgel capsules to store single doses of liquid medicines.
Health care, food, and cosmetic uses
Sorbitol often is used in modern cosmetics as a humectant and thickener. It is also used in mouthwash and toothpaste. Some transparent gels can be made only with sorbitol, because of its high refractive index.
Sorbitol is used as a cryoprotectant additive (mixed with sucrose and sodium polyphosphates) in the manufacture of surimi, a processed fish paste. It is also used as a humectant in some cigarettes.
Beyond its use as a sugar substitute in reduced-sugar foods, sorbitol is also used as a humectant in cookies and low-moisture foods like peanut butter and fruit preserves. In baking, it is also valuable because it acts as a plasticizer, and slows down the staling process.
Miscellaneous uses
A mixture of sorbitol and potassium nitrate has found some success as an amateur solid rocket fuel. It has similar performance to sucrose-based rocket candy, but is easier to cast, less hygroscopic and does not caramelize.
Sorbitol is identified as a potential key chemical intermediate for production of fuels from biomass resources. Carbohydrate fractions in biomass such as cellulose undergo sequential hydrolysis and hydrogenation in the presence of metal catalysts to produce sorbitol. Complete reduction of sorbitol opens the way to alkanes, such as hexane, which can be used as a biofuel. Hydrogen required for this reaction can be produced by aqueous phase catalytic reforming of sorbitol.
- 19 C6H14O6 → 13 C6H14 + 36 CO2 + 42 H2O
The above chemical reaction is exothermic, and 1.5 moles of sorbitol generate approximately 1 mole of hexane. When hydrogen is co-fed, no carbon dioxide is produced.
Sorbitol based polyols are used in the production of polyurethane foam for the construction industry.
It is also added after electroporation of yeasts in transformation protocols, allowing the cells to recover by raising the osmolarity of the medium.
Medical importance
Aldose reductase is the first enzyme in the sorbitol-aldose reductase pathway responsible for the reduction of glucose to sorbitol, as well as the reduction of galactose to galactitol. Too much sorbitol trapped in retinal cells, the cells of the lens, and the Schwann cells that myelinate peripheral nerves, is a frequent result of long-term hyperglycemia that accompanies poorly controlled diabetes. This can damage these cells, leading to retinopathy, cataracts and peripheral neuropathy, respectively.
Sorbitol is fermented in the colon and produces short-chain fatty acids, which are beneficial to overall colon health.
Potential adverse effects
Sorbitol may cause allergic reactions in some people. Common side effects from use as a laxative are stomach cramps, vomiting, diarrhea or rectal bleeding.
