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 ]
Xylooligosaccharides act as a prebiotic, [3] [4] selectively feeding beneficial bacteria such as bifidobacteria and lactobacilli within the digestive tract. A large number of clinical trials have been conducted with XOS, demonstrating a variety of health benefits, including improvements in blood sugars and lipids, digestive health benefits ...
The word "alcohol" derives from the Arabic kohl (Arabic: الكحل, romanized: al-kuḥl), a powder used as an eyeliner. [12] The first part of the word ( al- ) is the Arabic definite article , equivalent to the in English.
Kapok seed oil, obtained from any of several related tree species, all referred to as "Kapok trees", for example: Ceiba pentandra, Bombax ceiba and Bombax costatum – used as an edible oil, and in soap production.

Xylan (/ ˈ z aɪ l æ n /; [3] / ˈ z aɪ l ən / [4]) (CAS number: 9014-63-5) is a type of hemicellulose, a polysaccharide consisting mainly of xylose residues. It is found in plants, in the secondary cell walls of dicots and all cell walls of grasses. [5]
For example, in the UK, food companies are required to include the "E number(s)" in the ingredients that are added as part of the manufacturing process. Many components of naturally occurring healthy foods and vitamins have assigned E numbers (and the number is a synonym for the chemical component), e.g. vitamin C ( E300 ) and lycopene ( E160d ...
