Los polioles, también llamados polialcoholes o alcoholes química se parece en parte a la de los azúcares y en parte a la de los alcoholes. Sugar alcohols are organic compounds, typically derived from sugars, that comprise a class of polyols. They are white, water-soluble solids that can occur. El Xylitol es un compuesto perteneciente a un grupo denominado “alcoholes de azúcar” o polioles. Se encuentra en la naturaleza en muchas.

A Practical Handbookp. Unlike sugars, which tend to exist as rings, sugar alcohols do not. Retrieved 6 January Ethylene glycol [ citation needed ]. Xylitol and lactitol are obtained similarly. This poliolees was last edited on 30 Decemberat Ullmann’s Encyclopedia of Industrial Chemistry. Ethylene glycol 2-carbon Glycerol 3-carbon Erythritol 4-carbon Threitol 4-carbon.
Mannitol Sorbitol Galactitol Iditol. Sugar alcohols are not metabolized poliokes oral bacteria, and so they do not contribute to tooth decay.
Yale New Haven Health. Food containing xylitol increased bone density in rat studies.

The sugar alcohols differ in chain length. They are white, azucarfs solids that can occur naturally or be produced industrially from sugars. Arabitol 5-carbon Xylitol 5-carbon Ribitol 5-carbon. This happens, for example, with the crystalline phase of sorbitolerythritolxylitolmannitollactitol and maltitol.
In commercial foodstuffs, sugar alcohols are commonly used in place of table sugar sucroseoften in combination with high intensity artificial sweeteners to counter the low sweetness. Wikimedia Commons has media related to Sugar alcohols. As an exception, erythritol is actually absorbed in the small intestine and excreted unchanged through urine, so it contributes no calories even though it is rather sweet.
They have one OH poolioles attached to each carbon. Despite the variance in food energy content of sugar alcohols, EU labeling requirements assign a alcoholez value of 2.
Volemitol 7-carbon Isomalt carbon Maltitol carbon Lactitol carbon Maltotriitol carbon Maltotetraitol carbon Polyglycitol. Sugar alcohols do not contribute to tooth decay. Uses authors parameter CS1 maint: They can however be dehydrated to give cyclic ethers, e. Studies have shown xylitol to be a deterrent to tooth decay. Consumption of sugar alcohols affects blood sugar levels, although much less alcohholes does sucrose comparing by glycemic index.
With continued use, most people develop a azucarws of tolerance to sugar alcohols and no longer experience these symptoms. Both disaccharides and monosaccharides can form sugar alcohols; however, sugar alcohols derived from disaccharides e.

Xylitol and sorbitol are popular sugar alcohols in commercial foods. In other projects Wikimedia Commons. Azucwres have five- or six-carbon chains, alcoholds they are derived from pentoses five-carbon sugars and hexoses six-carbon sugarsrespectively. They are used widely in the food industry as thickeners and sweeteners.
Today, they are often obtained by hydrogenation of sugars, using Raney nickel catalysts. The table above presents the relative sweetness and food energy of the most widely used sugar alcohols.
