What is L-arabinose used for?
L-Arabinose, a monosaccharide extracted from plant gums, corn fiber, and beet pulps, is known to suppress obesity by regulating the fasting blood glucose level and the insulin resistance index (10).
What is the name of D-arabinose?
D-Arabinose, also known as (+/-)-arabinose or aloe sugar, belongs to the class of organic compounds known as pentoses. These are monosaccharides in which the carbohydrate moiety contains five carbon atoms. D-Arabinose is an extremely weak basic (essentially neutral) compound (based on its pKa).
Are D-arabinose and L-arabinose enantiomers?
(2S,3R,4R)-2,3,4,5-tetrahydroxypentanal. Aldehydo-D-arabinose is an aldehydo-arabinose and a D-arabinose. It is an enantiomer of an aldehydo-L-arabinose. (2S,3R,4R)-2,3,4,5-tetrahydroxypentanal is a natural product found in Ascochyta medicaginicola, Anabaena, and other organisms with data available.
Which is a property of D-arabinose?

Where is L-arabinose found?
L-Arabinose and its functionality L-Arabinose is a rare type of sugar that naturally occurs in the hemicelluloses structure of most fruits and vegetables. The highest concentrations of L-Arabinose can be found in instant coffee, wine and sake.
What is the relationship between D-arabinose and L-arabinose?
L-Arabinose is a common constituent of plant poly- saccharides. D-Arabinose occurs in the glycosides of certain plants and is less common than the L-isomer. From the distribution of the isomers of arabinose it would be expected that L-arabinose would be utilized readily by more fungi than D-arabinose.
Is arabinose ad or L enantiomer?
The enantiomer of D-arabinose is structure C, whose name is L-arabinose.
Is D-arabinose a reducing sugar?
Reducing sugars include glucose, fructose, glyceraldehyde, lactose, arabinose and maltose. All monosaccharides which contain ketone groups are known as ketoses, and those which contain aldehyde groups are known as aldoses.
What is the relationship between D arabinose and D-Ribose?
Epimers are diastereomers that contain more than one chiral center but differ from each other in the absolute configuration at only one chiral center. Thus, D-ribose and D-arabinose are epimers (and diastereomers), because they differ in configuration only at C-2 .
What is the difference between arabinose and ribose?
The structure of the arabinose is very similar to ribose sugar of human purine bases; the difference is only at one hydroxyl group position ( Fig. 1). Based on that, an idea to chemically-synthesized cytosine arabinoside which is very similar to human cytosine deoxyribose was come up.
