Description
DL-Xylose, also known as xylose, is a monosaccharide of the aldopentose type, which means that it contains five carbon atoms and includes an aldehyde functional group. It is the precursor to hemicellulose, one of the main components of plant cell walls. Xylose is a sugar first isolated from wood and is found in various plant sources.
Uses
Used in Pharmaceutical Industry:
DL-Xylose is used as a diagnostic tool for evaluating malabsorption syndromes and small intestinal bacterial overgrowth. It is administered orally, and its urinary excretion is measured to assess the absorption capacity of the small intestine.
Used in Food and Beverage Industry:
DL-Xylose is used as a sweetener in various food and beverage products. It is a low-calorie alternative to sugar and has a glycemic index of 13, making it suitable for individuals with diabetes or those looking to reduce their sugar intake.
Used in Chemical Industry:
DL-Xylose is used as a starting material for the production of xylitol, a sugar alcohol with various applications, including as a sweetener in oral care products, pharmaceuticals, and food products. Xylitol also has antimicrobial properties and can be used in mouthwashes and toothpastes to promote oral health.
Used in Biofuel Production:
DL-Xylose can be fermented by certain microorganisms to produce biofuels, such as ethanol. This process is particularly relevant in the context of lignocellulosic biomass conversion, where xylose is a major component of the hemicellulose fraction.
Used in Animal Feed Industry:
DL-Xylose can be used as a nutritional supplement in animal feed, providing an additional source of energy and promoting overall animal health.
Check Digit Verification of cas no
The CAS Registry Mumber 25990-60-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,9 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25990-60:
(7*2)+(6*5)+(5*9)+(4*9)+(3*0)+(2*6)+(1*0)=137
137 % 10 = 7
So 25990-60-7 is a valid CAS Registry Number.

Synthesis of racemic ribose from D-glucose
Miculka, Christian

Racemic ribose is a valuable starting material for investigations of the origins of biomolecular homochirality. It can be synthesized in seven steps starting from D-glucose.
THE FORMOIN REACTION
Castells, Josep,Lopez-Calahorra, Francisco,Geijo, Fernando
, p. 197 - 208 (2007/10/02)
The formoin reaction, i.e., the autocondensation of formaldehyde in an aprotic solvent catalysed by the conjugate base of a thiazolium ion, has been studied in detail.Glucose, galactose, dihyroxyacetone dimer, xylose, and arabinose have been identified as products.The influence of catalysts, temperature, basicity, and reaction time is documented.N,N-Dimethylformamide is a more convenient solvent than ether, benzene, or diglyme.Ethyldi-isopropylamine affords better yields of carbohydrate material than triethylamine.At =60 deg, aldol condensations are reduced to a minimum.After 1-2 h of reaction (depending on the conditions), the yields begin to decrease and become zero after ca. 24 h.
