Xylitol occurs naturally in small amounts in plums, strawberries, cauliflower, and pumpkin; humans and many other animals make trace amounts during metabolism of carbohydrates. [10] Unlike most sugar alcohols, xylitol is achiral. [12] Most other isomers of pentane-1,2,3,4,5-pentol are chiral, but xylitol has a plane of symmetry.
Sugar alcohols can be, and often are, produced from renewable resources.Particular feedstocks are starch, cellulose and hemicellulose; the main conversion technologies use H 2 as the reagent: hydrogenolysis, i.e. the cleavage of C−O single bonds, converting polymers to smaller molecules, and hydrogenation of C=O double bonds, converting sugars to sugar alcohols.
Sucrose (table sugar) is the prototypical example of a sweet substance. Sucrose in solution has a sweetness perception rating of 1, and other substances are rated relative to this. [ 13 ] For example, another sugar, fructose , is somewhat sweeter, being rated at 1.7 times the sweetness of sucrose. [ 13 ]
Xylitol is a sugar alcohol that is found in small amounts in fruit and vegetables, and the human body also produces it. As an additive, it looks and tastes like sugar but has 40% fewer calories.
Xylitol is a naturally occurring sugar alcohol that is used in different products as an alternative to sucrose (table sugar). As of 2015 the evidence concerning the use of xylitol in chewing gum was insufficient to determine if it is effective at preventing caries. [117] [118] [119]
Attar, or qatir (Arabic: قَطْر) is a type of sweet syrup used in the preparation of Middle Eastern desserts.It is made of primarily sugar and water, and is reduced slightly until somewhat golden and thicker.
In North America, common sugar substitutes include aspartame, monk fruit extract, saccharin, sucralose and stevia. Cyclamate is prohibited from being used as a sweetener within the United States, but is allowed in other parts of the world. [3] Sorbitol, xylitol and lactitol are examples of sugar alcohols (also known as polyols). These are, in ...
In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [ 3 ] [ 4 ] Alcohols range from the simple, like methanol and ethanol , to complex, like sugars and cholesterol .
