Cytosine
Cytosine, also known as C, belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Cytosine is also classified as a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2). Cytosine is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). The nucleoside of cytosine is cytidine. In Watson-Crick base pairing, cytosine forms three hydrogen bonds with guanine. Cytosine was discovered and named by Albrecht Kossel and Albert Neumann in 1894 when it was hydrolyzed from calf thymus tissues. Cytosine exists in all living species, ranging from bacteria to plants to humans. Within cells, cytosine can undergo several enzymatic reactions. It can be methylated into 5-methylcytosine by an enzyme called DNA methyltransferase (DNMT) or be methylated and hydroxylated to make 5-hydroxymethylcytosine. The DNA methyltransferase (DNMT) family of enzymes transfer a methyl group from S-adenosyl-l-methionine (SAM) to the 5’ carbon of cytosine in a molecule of DNA. High levels of cytosine can be found in the urine of individuals with severe combined immunodeficiency syndrome (SCID). Cytosine concentrations as high as (23-160 mmol/mol creatinine) were detected in SCID patients compared to normal levels of <2 mmol/mol creatinine (PMID: 262183). Cytosine is an aminopyrimidine that is pyrimidin-2-one having the amino group located at position 4. It has a role as a human metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. It is a pyrimidine nucleobase, a pyrimidone and an aminopyrimidine. Cytosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Cytosine is a natural product found in Streptomyces antibioticus, Salmonella enterica, and other organisms with data available. Cytosine is a pyrimidine base found in DNA and RNA that pairs with guanine. Cytosine is a metabolite found in or produced by Saccharomyces cerevisiae. A pyrimidine base that is a fundamental unit of nucleic acids. See also: Pyrimidine (related). A pyrimidine base that is a fundamental unit of nucleic acids. The deamination of cytosine alone is apparent and the nucleotide of cytosine is the prime mutagenic nucleotide in leukaemia and cancer. [HMDB]. Cytosine is found in many foods, some of which are beech nut, turmeric, grass pea, and cucurbita (gourd). An aminopyrimidine that is pyrimidin-2-one having the amino group located at position 4.

Geraniol
Geraniol, also known as beta-Geraniol, (E)-nerol (the isomer of nerol) or geranyl alcohol, is a monoterpenoid alcohol. It belongs to the class of organic compounds known as acyclic monoterpenoids. These are monoterpenes that do not contain a cycle. Monoterpenoids are terpenes that contain 10 carbon atoms and are comprised of two isoprene units. In plants, the biosynthesis of monoterpenes is known to occur mainly through the methyl-erythritol-phosphate (MEP) pathway in the plastids (PMID:7640522 ). Geranyl diphosphate (GPP) is a key intermediate in the biosynthesis of cyclic monoterpenes. GPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. beta-Geraniol is an isoprenoid lipid molecule that is very hydrophobic, practically insoluble in water, and relatively neutral. beta-Geraniol has a sweet, citrus, and floral taste. beta-Geraniol is found in highest concentrations in common grapes, black walnuts, and common thymes and in lower concentrations in cardamoms, common oregano, and gingers. beta-Geraniol has also been detected in lemon verbena, oval-leaf huckleberries, common pea, sweet cherries, and nopals. It is found as an alcohol and as its ester in many essential oils including geranium oil. It is the primary part of rose oil, palmarosa oil, and citronella oil (Java type) and occurs in small quantities in geranium, lemon, and many other essential oils. Because it has a rose-like odor, it is commonly used in perfumes. It is used to create flavors such as peach, raspberry, grapefruit, red apple, plum, lime, orange, lemon, watermelon, pineapple, and blueberry. An alternate application has been found in the use of insect repellents or deterrants. Though it may repel mosquitoes, flies, lice, cockroaches, ants, and ticks, it is also produced by the scent glands of honey bees to help them mark nectar-bearing flowers and locate the entrances to their hives (http//doi:10.1051/apido:19900403). Extensive testing by Dr. Jerry Butler at the University of Florida has shown geraniol to be one of natures most effective insect repellents (PMID:20836800). Nerol is the (2Z)-stereoisomer of 3,7-dimethylocta-2,6-dien-1-ol. It has been isolated from the essential oils from plants like lemon grass. It has a role as a volatile oil component, a plant metabolite and a fragrance. Nerol is a natural product found in Eupatorium cannabinum, Vitis rotundifolia, and other organisms with data available. Nerol is a metabolite found in or produced by Saccharomyces cerevisiae. Constituent of many essential oils including neroli and bergamot oils.

6-Methyladenine
6-Methyladenine is a methylated adenine residue. The formation of internal 6-methyladenine (m6A) residues in eucaryotic messenger RNA (mRNA) is a postsynthetic modification in which S-adenosyl-L-methionine (SAM) serves as the methyl donor. 6-Methyladenine residues have also been localized to heterogeneous nuclear RNA (HnRNA), and for the most part these residues are conserved during mRNA processing. Although the biological significance of internal adenine methylation in eucaryotic mRNA remains unclear, a great deal of research has indicated that this modification may be required for mRNA transport to the cytoplasm, the selection of splice sites or other RNA processing reactions. The presence of m6A residues increases the in vitro translation efficiency of dihydrofolate reductase; an inhibition of m6A residues in dihydrofolate reductase transcripts significantly alters their rate of translation. m6A is found in many human fluids: oviductal fluid, blood plasma and urine. (PMID: 1551452, 8925412, 10481270, 16083005, 16684535, 3506820, 3728186) [HMDB] 6-Methyladenine is a methylated adenine residue.

Diltiazem
Diltiazem is only found in individuals that have used or taken this drug. It is a benzothiazepine derivative with vasodilating action due to its antagonism of the actions of the calcium ion in membrane functions. It is also teratogenic. [PubChem]Possibly by deforming the channel, inhibiting ion-control gating mechanisms, and/or interfering with the release of calcium from the sarcoplasmic reticulum, diltiazem, like verapamil, inhibits the influx of extracellular calcium across both the myocardial and vascular smooth muscle cell membranes. The resultant inhibition of the contractile processes of the myocardial smooth muscle cells leads to dilation of the coronary and systemic arteries and improved oxygen delivery to the myocardial tissue.

Inosine triphosphate
Inosine triphosphate (ITP) is an intermediate in the purine metabolism pathway. Relatively high levels of ITP in red cells are found in individuals as result of deficiency of inosine triphosphatase (EC 3.1.3.56, ITPase) ITPase is a cytosolic nucleoside triphosphate pyrophosphohydrolase specific for ITP catalysis to inosine monophosphate (IMP) and deoxy-inosine triphosphate (dITP) to deoxy-inosine monophosphate. ITPase deficiency is not associated with any defined pathology other than the characteristic and abnormal accumulation of ITP in red blood cells. Nevertheless, ITPase deficiency may have pharmacogenomic implications, and the abnormal metabolism of 6-mercaptopurine in ITPase-deficient patients may lead to thiopurine drug toxicity. ITPases function is not clearly understood but possible roles for ITPase could be to prevent the accumulation of rogue nucleotides which would be otherwise incorporated into DNA and RNA, or compete with nucleotides such as GTP in signalling processes.

Cyclic GMP
Cyclic-gmp, also known as cgmp or guanosine 3,5-cyclic monophosphate, is a member of the class of compounds known as 3,5-cyclic purine nucleotides. 3,5-cyclic purine nucleotides are purine nucleotides in which the oxygen atoms linked to the C3 and C5 carbon atoms of the ribose moiety are both bonded the same phosphorus atom of the phosphate group. Cyclic-gmp is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Cyclic-gmp can be found in a number of food items such as common sage, jews ear, java plum, and pepper (c. chinense), which makes cyclic-gmp a potential biomarker for the consumption of these food products. Cyclic-gmp can be found primarily in blood and cerebrospinal fluid (CSF), as well as throughout most human tissues. Cyclic-gmp exists in all living species, ranging from bacteria to humans. Moreover, cyclic-gmp is found to be associated with headache. Guanosine cyclic 3,5-(hydrogen phosphate). A guanine nucleotide containing one phosphate group which is esterified to the sugar moiety in both the 3- and 5-positions. It is a cellular regulatory agent and has been described as a second messenger. Its levels increase in response to a variety of hormones, including acetylcholine, insulin, and oxytocin and it has been found to activate specific protein kinases. (From Merck Index, 11th ed).

Dimethylamine
Dimethylamine (DMA) is an organic secondary amine. It is a colorless, liquefied and flammable gas with an ammonia and fish-like odor. Dimethylamine is abundantly present in human urine. Main sources of urinary DMA have been reported to include trimethylamine N-oxide, a common food component, and asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide (NO) synthesis. ADMA is excreted in the urine in part unmetabolized and in part after hydrolysis to DMA by dimethylarginine dimethylaminohydrolase (DDAH). Statistically significant increases in urinary DMA have been found in individuals after the consumption of fish and seafoods. The highest values were obtained for individuals that consumed coley, squid and whiting with cod, haddock, sardine, skate and swordfish (PMID: 18282650). It has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). As a pure chemical substance Dimethylamine is used as dehairing agent in tanning, in dyes, in rubber accelerators, in soaps and cleaning compounds and as an agricultural fungicide. In the body, DMA also undergoes nitrosation under weak acid conditions to give dimethlynitrosamine. Study has shown that DMA is a metabolite of Arthrobacter and Micrococcus (PMID: 11422368 ; PMID: 7191). Aminating agent in the manuf. of ion-exchange resins for food processing KEIO_ID D103
Methane
Methane (CH4), is a gas produced by a group of colonic anaerobes, absorbed from the colon and excreted in expired air. As a result, breath CH4 excretion can be used as an indicator of the in situ activity of the methanogenic flora. All CH4 produced in human beings is a metabolic product of intestinal bacteria, and about 50\\% of CH4 produced in the gut is absorbed and excreted in expired air. Because there appears to be no catabolism of this gas by other colonic organisms or host cells, breath CH4 measurements provide a rapid, simple means of semi quantitatively assessing the ongoing in situ metabolism of the methanogenic flora. It could seem likely that the intracolonic activity of a variety of bacteria similarly might be assessed quantitatively via analysis of expired air. However, the application of this methodology has been confounded by the rapid catabolism of many volatile bacterial products by other bacteria or human tissue. A striking aspect of the studies of breath CH4 measurements is the enormous individual variations in the excretion of this gas. Virtually all children under 5 years of age and 66\\% of the adult population do not exhale appreciable quantities of CH4. The remaining 34\\% of the adult population has appreciable breath methane concentrations of up to 80 ppm (mean, 15.2 ppm; median, 11.8 ppm). On this basis the population can be divided into CH4 producers or nonproducers, although a more accurate term would be to define subjects as being low or high CH4 producers. The primary methanogen present in the human colon, Methanobrevibacter smithii, produces methane via a reaction that relies entirely on H2 produced by other organisms to reduce CO2 to CH4. Thus, breath CH4 concentrations might be expected to mirror breath H2 concentrations; however, the high levels of CH4 observed in the fasting state may result from H2 derived from endogenous rather than dietary substrates. A diverse assortment of conditions has been associated with a high prevalence of methane producers including diverticulosis, cystic fibrosis, high fasting serum cholesterol levels, encopresis in children, and aorto-iliac vascular disease, whereas obesity (measured as skin-fold thickness) was related inversely to methane production. The challenge that remains is to determine to what extent methanogens actively influence body physiology vs. simply serve as passive indicators of colonic function. (PMID: 16469670, Clinical Gastroenterology and Hepatology Volume 4, Issue 2, February 2006, Pages 123-129). Methane can be found in Desulfovibrio, Methanobacterium, Methanobrevibacter, Methanococcus, Methanocorpusculum, Methanoculleus, Methanoflorens, Methanofollis, Methanogenium, Methanomicrobium, Methanopyrus, Methanoregula, Methanosaeta, Methanosarcina, Methanosphaera, Methanospirillium, Methanothermobacter (Wikipedia).

Ethylbenzene
Ethyl benzene, also known as ethylbenzol or alpha-methyltoluene, belongs to benzene and substituted derivatives class of compounds. Those are aromatic compounds containing one monocyclic ring system consisting of benzene. Ethyl benzene can be found in black walnut and safflower, which makes ethyl benzene a potential biomarker for the consumption of these food products. Ethyl benzene can be found primarily in blood and feces. Ethyl benzene exists in all eukaryotes, ranging from yeast to humans. Ethyl benzene is formally rated as possibly a carcinogenic (IARC 2B) potentially toxic compound. Ethyl benzene is an organic compound with the formula C6H5CH2CH3. It is a highly flammable, colorless liquid with an odor similar to that of gasoline. This monocyclic aromatic hydrocarbon is important in the petrochemical industry as an intermediate in the production of styrene, the precursor to polystyrene, a common plastic material. In 2012, more than 99\\% of ethylbenzene produced was consumed in the production of styrene. Ethyl benzene is also used to make other chemicals, in fuel, and as a solvent in inks, rubber adhesives, varnishes, and paints. Ethyl benzene exposure can be determined by testing for the breakdown products in urine . Following oral exposure, a gastric lavage is recommended. Protect airway by placement in Trendelenburg and left lateral decubitus position or by endotracheal intubation. Control any seizures first. Following inhalation, move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Following eye exposure, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. In case of dermal exposure, remove contaminated clothing and wash exposed area thoroughly with soap and water. Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines. Some chemicals can produce systemic poisoning by absorption through intact skin. Carefully observe patients with dermal exposure for the development of any systemic signs or symptoms and administer symptomatic treatment as necessary (T36) (T3DB). Ethylbenzene belongs to the family of Substituted Benzenes. These are aromatic compounds containing a benzene substituted at one or more positions.

1,3-Butadiene
1,3-Butadiene is a simple conjugated diene with the formula C4H6. It is an important industrial chemical used as a monomer in the production of synthetic rubber. When the word butadiene is used, most of the time it refers to 1,3-butadiene. 1,3-Butadiene is inconvenient for laboratory use because it is a flammable gas subject to polymerization on storage. 3-Butadiene cyclic sulfone (sulfolene) is a convenient solid storable source for 1,3-butadiene for many laboratory purposes when the generation of sulfur dioxide byproduct in the reaction mixture is not objectionable. Long-term exposure has been associated with cardiovascular disease, there is a consistent association with leukemia, and weaker association with other cancers. Most butadiene is polymerized to produce synthetic rubber. While polybutadiene itself is a very soft, almost liquid material, copolymers prepared from mixtures of butadiene with styrene and/or acrylonitrile, such as acrylonitrile butadiene styrene (ABS), acrylonitrile butadiene (NBR) and styrene-butadiene (SBR) are tough and elastic. SBR is the material most commonly used for the production of automobile tires. Smaller amounts of butadiene are used to make the nylon intermediate, adiponitrile, by the addition of a molecule of hydrogen cyanide to each of the double bonds in a process called hydrocyanation developed by DuPont. Other synthetic rubber materials such as chloroprene, and the solvent sulfolane are also manufactured from butadiene. Butadiene is used in the industrial production of 4-vinylcyclohexene via a Diels Alder dimerization reaction and the vinylcyclohexene is a common impurity found in butadiene upon storage. Cyclooctadiene and cyclododecatriene are produced via nickel- or titanium-catalyzed dimerization and trimerization reactions, respectively. Butadiene is also useful in the synthesis of cycloalkanes and cycloalkenes, as it reacts with double and triple carbon-carbon bonds through the Diels-Alder reaction. The name butadiene can also refer to the isomer, 1,2-butadiene, which is a cumulated diene. However, this allene is difficult to prepare and has no industrial significance. This diene is also not expected to act as a diene in a Diels-Alder reaction due to its structure. To effect a Diels-Alder reaction only a conjugated diene will suffice.
