Usage

General Description

Dl-arabinose is a simple sugar derivative of arabinose, a naturally occurring pentose monosaccharide. It is classified as a rare sugar due to its limited presence in nature, and is typically found in small quantities in plants such as sugar beet, pea hulls, and gum arabic. Dl-arabinose has potential applications in the food and pharmaceutical industries as a low-calorie sweetener and as a prebiotic that promotes the growth of beneficial gut bacteria. It is also used in research as a component of culture media for microbiological studies. Additionally, dl-arabinose has been studied for its potential role in preventing and managing certain metabolic disorders, although further research is needed to fully understand its physiological effects in humans.

Synthesis of racemic ribose from D-glucose

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

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.
