D-Xylose
Xylose 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. Xylose is a sugar first isolated from wood, and named for it. Xylose is classified as 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 constituents of biomass. D-Xylopyranose is found in flaxseed. D-(+)-xylose (Xylose) is a natural compound that is catalyzed by xylose isomerase to form xylulose, which is a key step in the anaerobic ethanol fermentation of xylose. D-(+)-xylose (Xylose) is a natural compound that is catalyzed by xylose isomerase to form xylulose, which is a key step in the anaerobic ethanol fermentation of xylose.

D-Ribose
D-Ribose, commonly referred to as simply ribose, is a five-carbon sugar found in all living cells. Ribose is not an essential nutrient because it can be synthesized by almost every tissue in the body from other substances, such as glucose. It is vital for life as a component of DNA, RNA, ATP, ADP, and AMP. In nature, small amounts of ribose can be found in ripe fruits and vegetables. Brewers yeast, which has a high concentration of RNA, is another rich source of ribose. D-ribose is also a component of many so-called energy drinks and anti-ageing products available on the market today. Ribose is a structural component of ATP, which is the primary energy source for exercising muscle. The adenosine component is an adenine base attached to the five-carbon sugar ribose. ATP provides energy to working muscles by releasing a phosphate group, hence becoming ADP, which in turn may release a phosphate group, then becoming AMP. During intense muscular activity, the total amount of ATP available is quickly depleted. In an effort to correct this imbalance, AMP is broken down in the muscle and secreted from the cell. Once the breakdown products of AMP are released from the cell, the energy potential (TAN pool) of the muscle is reduced and ATP must then be reformed using ribose. Ribose helps restore the level of adenine nucleotides by bypassing the rate-limiting step in the de novo (oxidative pentose phosphate) pathway, which regenerates phosphoribosyl pyrophosphate (PRPP), the essential precursor for ATP. If ribose is not readily available to a cell, glucose may be converted to ribose. Ribose supplementation has been shown to increase the rate of ATP resynthesis following intense exercise. The use of ribose in men with severe coronary artery disease resulted in improved exercise tolerance. Hence, there is interest in the potential of ribose supplements to boost muscular performance in athletic activities (PMID: 17618002, Curr Sports Med Rep. 2007 Jul;6(4):254-7.). Ribose, also known as D-ribose or alpha-delta-ribose-5, is a member of the class of compounds known as pentoses. Pentoses are monosaccharides in which the carbohydrate moiety contains five carbon atoms. Ribose is very soluble (in water) and a very weakly acidic compound (based on its pKa). Ribose can be found in a number of food items such as lemon verbena, devilfish, watercress, and chicory roots, which makes ribose a potential biomarker for the consumption of these food products. Ribose can be found primarily in most biofluids, including urine, cerebrospinal fluid (CSF), saliva, and feces, as well as throughout most human tissues. Ribose exists in all living species, ranging from bacteria to humans. In humans, ribose is involved in the pentose phosphate pathway. Ribose is also involved in few metabolic disorders, which include glucose-6-phosphate dehydrogenase deficiency, ribose-5-phosphate isomerase deficiency, and transaldolase deficiency. Moreover, ribose is found to be associated with ribose-5-phosphate isomerase deficiency. The ribose β-D-ribofuranose forms part of the backbone of RNA. It is related to deoxyribose, which is found in DNA. Phosphorylated derivatives of ribose such as ATP and NADH play central roles in metabolism. cAMP and cGMP, formed from ATP and GTP, serve as secondary messengers in some signalling pathways . D-Ribose(mixture of isomers) is an energy enhancer, and acts as a sugar moiety of ATP, and widely used as a metabolic therapy supplement for chronic fatigue syndrome or cardiac energy metabolism.

L-Arabinose
L-Arabinose (CAS: 5328-37-0) belongs to the class of compounds known as aldopentoses. An aldopentose is a monosaccharide containing five carbon atoms, including an aldehyde (CHO) functional group. Arabinose gets its name from gum arabic, from which it was first isolate. Most saccharides found in nature are in the "D"-form, however, L-arabinose is in fact more common than D-arabinose. L-arabinose is found in nature as a component of biopolymers such as hemicellulose and pectin. L-arabinose is found in all organisms from bacteria to plants to animals. Arabinose is the second most abundant pentose in lignocellulosic biomass after xylose. There are two different arabinose utilization pathways in nature: bacterial and fungal. The bacterial pathway converts arabinose into xylulose-5-P via ribulose-5-P using three enzymes (L-arabinose isomerase, L-ribulokinase, and L-ribulose-5-P 4-epimerase) after which it enters the pentose phosphate pathway for ethanol production. The fungal pathway converts arabinose into L-arabinitol by aldose reductase (AR) or XR, L-xylulose by L-arabinitol 4-dehydrogenase (LAD), xylitol by L-xylulose reductase (LXR), D-xylulose by xylulose dehydrogenase (XDH), and D-xylulose-5-P by xylulose kinase (XK), and lastly enters the nonoxidative pentose phosphate pathway for further metabolism. Arabinose has a sweet taste and is one of the most abundant components released by complete hydrolysis of non-starch polysaccharides (NSP) of vegetable origin. Although widely present in nature, L-arabinose is rarely used in food production or food flavoring, and its physiological effects in vivo have received little attention. L-arabinose is known to selectively inhibit intestinal sucrase activity in a non-competitive manner. Sucrase is the enzyme that breaks down sucrose into glucose and fructose in the small intestine. As a result, L-arabinose suppresses plasma glucose increase due to sucrose ingestion. The presence of arabinose in urine may indicate overgrowth of intestinal yeast such as Candida albicans or other yeast/fungus species. L-arabinose is also a microbial metabolite found in, and produced by, Mycobacterium (PMID: 16232643). In a rare case of two autistic brothers that were not associated with any known metabolic disease, it was found the median value for L-arabinose in their urine samples was 179 umol/mmol creatinine, nearly six times greater than normal children (PMID: 11238761, 8931641, 1390604, 7628083).

Since L-xylulose is a reducing sugar like D-glucose, pentosuria patients have been wrongly diagnosed in the past to be diabetic.
D-Xylulose
D-xylulose is a monosaccharide containing five carbon atoms. D-xylulose is converted from xylitol by the enzyme NAD+-linked xylitol dehydrogenase (EC 1.1.1.9) in the glucuronate pathway, the most important xylitol-handling metabolic pathway in mammals. This activity has been described in human erythrocytes. Most likely, D-xylulose (as well as D-arabinose or D-ribulose) is a precursor of the pentiol D-arabitol, since pentitols are derived from their corresponding pentose phosphate precursors via pentoses. This pathway can play a role in inherited metabolic disorders underlying the accumulation of pentitols e.g., ribose 5-phosphate isomerase deficiency and transaldolase deficiency. Although pentitols are present in all living organisms, knowledge concerning their metabolism is limited. (PMID: 15234337, Mol Genet Metabolite 2004 Jul;82(3):231-7.) [HMDB].

7-Methylhypoxanthine
7-Methylhypoxanthine is a methyl derivative of xanthine, found occasionally in human urine. Methylated purines originate from the metabolism of methylxanthines (caffeine, theophylline and theobromine. Purine derivatives in urinary calculi could be considered markers of abnormal purine metabolism. The content of a purine derivative in stone depends on its average urinary excretion in the general population, similarity to the chemical structure of uric acid, and content of the latter in stone. This suggests that purines in stones represent a solid solution with uric acid as solvent. It is also plausible that methylxanthines, ubiquitous components of the diet and drugs, are involved in the pathogenesis of urolithiasis. Caffeine is metabolized via successive pathways mainly catalyzed by CYP1A2, xanthine oxidase or N-acetyltransferase-2 to give 14 different metabolites. CYP1A2 activity shows an inter-individual variability among the population. CYP1A2, an isoform of the CYP1A cytochrome P450 super-family, is involved in the metabolism of many drugs and plays a potentially important role in the induction of chemical carcinogenesis.
