xylose

DL-Xylose ((±)-Xylos) is a sugar first derived from wood. DL-Xylose is classified as a monosaccharide of the aldopentose type.

L-Xylose (L-(-)-Xylose), a levo-isomer of Xylose, is classified as an aldopentose-type monosaccharide.

D-(+)-Xylose (Wood sugar) is an aldopentose - a monosaccharide containing five carbon atoms and an aldehyde functional group. It has chemical formula C5H10O5 and is 40% as sweet as sucrose. Xylose is also found in mucopolysaccharides of connective tissue and sometimes in the urine. Xylose is the first sugar added to serine or threonine residues during proteoglycan type O-glycosylation. Therefore xylose is involved in the biosythetic pathways of most anionic polysaccharides such as heparan sulphate and chondroitin sulphate. In medicine, xylose is used to test for malabsorption by administering a xylose solution to the patient after fasting. If xylose is detected in the blood and or urine within the next few hours, it has been absorbed by the intestines. Xylose is said to be one of eight sugars which are essential for human nutrition, the others being galactose, glucose, mannose, N-acetylglucosamine, N-acetylgalactosamine, fucose, and sialic acid. . Xylose in the urine is a biomarker for the consumption of apples and other fruits.

D-Xylose ((2S,3R,4S,5R)-oxane-2,3,4,5-tetrol) is a monosaccharide widely found in yeast and involved in the metabolism of the organism.

UDP-xylose, a natural product isolated from Cryptococcus laurentii (NRRL Y-1401), serves as a sugar donor in the synthesis of glycoproteins, polysaccharides, various metabolites, and oligosaccharides across plants, vertebrates, and fungi [1] [2].

UDP-xylose disodium is a compound that can be isolated from Cryptococcus laurentii and is a sugar donor that can be used for the synthesis of glycoproteins, polysaccharides, various metabolites and oligosaccharides in plants, vertebrates and fungi.

D-Sorbitol (Sorbitol) is a polyhydric alcohol with about half the sweetness of sucrose, occurring naturally and also produced synthetically from glucose. Formerly used as a diuretic, it may still be used as a laxative and in irrigating solutions for certain surgical procedures. It is also utilized in various manufacturing processes, as a pharmaceutical aid, and in several research applications.

Xylitol (Ribitol) is a five-carbon sugar alcohol derived from XYLOSE by reduction of the carbonyl group. It is as sweet as sucrose and used as a noncariogenic sweetener.

Xylotetraose, a hydrolysis product of xylan, is a polysaccharide composed mainly of β-D-xylose units linked similarly to cellulose.

1,4-b-D-Xylopentaose consists of five b-1,4 xylose sugars

Xylohexaose is a hexasaccharide consisting of six xylose residues.
