Metabolite Identification
Common NameD-Xylose
DescriptionXylose or 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 found in the embryos of most edible plants. The polysaccharide xylan, which is closely associated with cellulose, consists practically entirely of d-xylose. Corncobs, cottonseed hulls, pecan shells, and straw contain considerable amounts of this sugar. 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. (Wikipedia ). Xylose in the urine is a biomarker for the consumption of apples and other fruits.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the NADPH-dependent reduction of a wide variety of carbonyl-containing compounds to their corresponding alcohols with a broad range of catalytic efficiencies.
Gene Name:
AKR1B1
Uniprot ID:
P15121
Molecular weight:
35853.125
Reactions
D-Xylitol + NADP → D-Xylose + NADPH + Hydrogen Iondetails
General function:
Involved in catalytic activity
Specific function:
Not Available
Gene Name:
DHDH
Uniprot ID:
Q9UQ10
Molecular weight:
36381.705
Reactions
D-Xylose + NADP → D-Xylono-1,5-lactone + NADPHdetails
D-Xylose + NADP → D-Xylono-1,5-lactone + NADPH + Hydrogen Iondetails
General function:
Involved in transporter activity
Specific function:
Involved in the sodium-dependent cotransport of myo-inositol (MI) with a Na(+):MI stoichiometry of 2:1. Exclusively responsible for apical MI transport and absorption in intestine. Also can transport D-chiro-inositol (DCI) but not L-fructose. Exhibits stereospecific cotransport of both D-glucose and D-xylose. May induce apoptosis through the TNF-alpha, PDCD1 pathway. May play a role in the regulation of MI concentration in serum, involving reabsorption in at least the proximal tubule of the kidney.
Gene Name:
SLC5A11
Uniprot ID:
Q8WWX8
Molecular weight:
69906.495
General function:
Not Available
Specific function:
Acts as all-trans-retinaldehyde reductase. Can efficiently reduce aliphatic and aromatic aldehydes, and is less active on hexoses (in vitro). May be responsible for detoxification of reactive aldehydes in the digested food before the nutrients are passed on to other organs.
Gene Name:
AKR1B10
Uniprot ID:
O60218
Molecular weight:
Not Available
Reactions
D-Xylitol + NADP → D-Xylose + NADPH + Hydrogen Iondetails
General function:
Not Available
Specific function:
Responsible for the 2-O-phosphorylation of xylose in the glycosaminoglycan-protein linkage region of proteoglycans thereby regulating the amount of mature GAG chains. Sulfated glycosaminoglycans (GAGs), including heparan sulfate and chondroitin sulfate, are synthesized on the so-called common GAG-protein linkage region (GlcUAbeta1-3Galbeta1-3Galbeta1-4Xylbeta1-O-Ser) of core proteins, which is formed by the stepwise addition of monosaccharide residues by the respective specific glycosyltransferases. Xylose 2-o-phosphorylation may influence the catalytic activity of B3GAT3 (GlcAT-I) which completes the precursor tetrasaccharide of GAG-protein linkage regions on which the repeating disaccharide region is synthesized.
