Adenosine
Adenosine is a ribonucleoside composed of a molecule of adenine attached to a ribofuranose moiety via a beta-N(9)-glycosidic bond. It has a role as an anti-arrhythmia drug, a vasodilator agent, an analgesic, a human metabolite and a fundamental metabolite. It is a purines D-ribonucleoside and a member of adenosines. It is functionally related to an adenine. The structure of adenosine was first described in 1931, though the vasodilating effects were not described in literature until the 1940s. Adenosine is indicated as an adjunct to thallium-201 in myocardial perfusion scintigraphy, though it is rarely used in this indication, having largely been replaced by [dipyridamole] and [regadenson]. Adenosine is also indicated in the treatment of supraventricular tachycardia. Adenosine was granted FDA approval on 30 October 1989. Adenosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Adenosine is an Adenosine Receptor Agonist. The mechanism of action of adenosine is as an Adenosine Receptor Agonist. Adenosine is a natural product found in Smilax bracteata, Mikania laevigata, and other organisms with data available. Adenosine is a ribonucleoside comprised of adenine bound to ribose, with vasodilatory, antiarrhythmic and analgesic activities. Phosphorylated forms of adenosine play roles in cellular energy transfer, signal transduction and the synthesis of RNA. Adenosine is a nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. For instance, adenosine plays an important role in energy transfer - as adenosine triphosphate (ATP) and adenosine diphosphate (ADP). It also plays a role in signal transduction as cyclic adenosine monophosphate, cAMP. Adenosine itself is both a neurotransmitter and potent vasodilator. When administered intravenously, adenosine causes transient heart block in the AV node. Because of the effects of adenosine on AV node-dependent supraventricular tachycardia, adenosine is considered a class V antiarrhythmic agent. Adenosine is a metabolite found in or produced by Saccharomyces cerevisiae. A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter.

When administered intravenously adenosine causes transient heart block in the AV node. Due to the effects of adenosine on AV node-dependent supraventricular tachycardia, adenosine is considered a class V antiarrhythmic agent. Overdoses of adenosine intake (as a drug) can lead to several side effects including chest pain, feeling faint, shortness of breath, and tingling of the senses. Serious side effects include a worsening dysrhythmia and low blood pressure. When present in sufficiently high levels, adenosine can act as an immunotoxin and a metabotoxin. An immunotoxin disrupts, limits the function, or destroys immune cells. A metabotoxin is an endogenous metabolite that causes adverse health effects at chronically high levels. Chronically high levels of adenosine are associated with adenosine deaminase deficiency. Adenosine is a precursor to deoxyadenosine, which is a precursor to dATP. A buildup of dATP in cells inhibits ribonucleotide reductase and prevents DNA synthesis, so cells are unable to divide. Since developing T cells and B cells are some of the most mitotically active cells, they are unable to divide and propagate to respond to immune challenges. High levels of deoxyadenosine also lead to an increase in S-adenosylhomocysteine, which is toxic to immature lymphocytes. Adenosine is a nucleoside composed of a molecule of adenine attached to a ribose sugar molecule (ribofuranose) moiety via a beta-N9-glycosidic bond. [Wikipedia].

Azelaic acid
Nonanedioic acid is an alpha,omega-dicarboxylic acid that is heptane substituted at positions 1 and 7 by carboxy groups. It has a role as an antibacterial agent, an antineoplastic agent, a dermatologic drug and a plant metabolite. It is a dicarboxylic fatty acid and an alpha,omega-dicarboxylic acid. It is a conjugate acid of an azelaate(2-) and an azelaate. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley. It is also produced by Malassezia furfur, also known as Pityrosporum ovale, which is a species of fungus that is normally found on human skin. Azelaic acid is effective against a number of skin conditions, such as mild to moderate acne, when applied topically in a cream formulation of 20\\\\\%. It works in part by stopping the growth of skin bacteria that cause acne, and by keeping skin pores clear. Azelaic acids antimicrobial action may be attributable to inhibition of microbial cellular protein synthesis. Azelaic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). The physiologic effect of azelaic acid is by means of Decreased Protein Synthesis, and Decreased Sebaceous Gland Activity. Azelaic Acid is a naturally occurring dicarboxylic acid produced by Malassezia furfur and found in whole grain cereals, rye, barley and animal products. Azelaic acid possesses antibacterial, keratolytic, comedolytic, and anti-oxidant activity. Azelaic acid is bactericidal against Proprionibacterium acnes and Staphylococcus epidermidis due to its inhibitory effect on the synthesis of microbial cellular proteins. Azelaic acid exerts its keratolytic and comedolytic effects by reducing the thickness of the stratum corneum and decreasing the number of keratohyalin granules by reducing the amount and distribution of filaggrin in epidermal layers. Azelaic acid also possesses a direct anti-inflammatory effect due to its scavenger activity of free oxygen radical. This drug is used topically to reduce inflammation associated with acne and rosacea. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley.

Azelaic acid (AZA) is a naturally occurring saturated nine-carbon dicarboxylic acid (COOH (CH2)7-COOH). It possesses a variety of biological actions both in vitro and in vivo. Interest in the biological activity of AZA arose originally out of studies of skin surface lipids and the pathogenesis of hypochromia in pityriasis versicolor infection. Later, it was shown that Pityrosporum can oxidize unsaturated fatty acids to C8-C12 dicarboxylic acids that are cornpetitive inhibitors of tyrosinase in vitro. Azelaic acid was chosen for further investigation and development of a new topical drug for treating hyperpigmentary disorders for the following reasons: it possesses a middle-range of antityrosinase activity, is inexpensive, and more soluble to be incorporated into a base cream than other dicarboxylic acids. Azelaic acid is another option for the topical treatment of mild to moderate inflammatory acne vulgaris. It offers effectiveness similar to that of other agents without the systemic side effects of oral antibiotics or the allergic sensitization of topical benzoyl peroxide and with less irritation than tretinoin. Azelaic acid is less expensive than certain other prescription acne preparations, but it is much more expensive than nonprescription benzoyl peroxide preparations. Whether it is safe and effective when used in combination with other agents is not known. (PMID: 7737781, 8961845). An alpha,omega-dicarboxylic acid that is heptane substituted at positions 1 and 7 by carboxy groups. Plants biology In plants, azelaic acid serves as a "distress flare" involved in defense responses after infection.[7] It serves as a signal that induces the accumulation of salicylic acid, an important component of a plant's defensive response.[8] Human biology The mechanism of action in humans is thought to be through the inhibition of hyperactive protease activity that converts cathelicidin into the antimicrobial skin peptide LL-37.[9] Polymers and related materials Esters of this dicarboxylic acid find applications in lubrication and plasticizers. In lubricant industries it is used as a thickening agent in lithium complex grease. With hexamethylenediamine, azelaic acid forms Nylon-6,9, which finds specialized uses as a plastic.[4] Medical Azelaic acid is used to treat mild to moderate acne, both comedonal acne and inflammatory acne.[10][11] It belongs to a class of medication called dicarboxylic acids. It works by killing acne bacteria that infect skin pores. It also decreases the production of keratin, which is a natural substance that promotes the growth[clarification needed] of acne bacteria.[12] Azelaic acid is also used as a topical gel treatment for rosacea, due to its ability to reduce inflammation.[11] It clears the bumps and swelling caused by rosacea. In topical pharmaceutical preparations and scientific research AzA is typically used in concentrations between 15\\\% and 20\\\% but some research demonstrates that in certain vehicle formulations the pharmaceutical effects of 10\\\% Azelaic acid has the potential to be fully comparable to that of some 20\\\% creams.[13] Acne treatment Azelaic acid is effective for mild to moderate acne when applied topically at a 15\\\%-20\\\% concentration.[14][15][16][17] In patients with moderate acne, twice daily application over 3 months of 20\\\% AzA significantly reduced the number of comedones, papules, and pustules;[18][19] at this strength, it’s considered to be as effective as benzoyl peroxide 5\\\%, tretinoin 0.05\\\%, erythromycin 2\\\%, and oral tetracycline at 500 mg-1000 mg.[20][21] In a comparative review of effects of topical AzA, Salicylic acid, Nicotinamide, Sulfur, Zinc, and alpha-hydroxy acid, AzA had more high-quality evidence of effectiveness than the rest.[22] Results can be expected after 4 weeks of twice-daily treatment. The effectiveness of long term use is unclear, but it’s been recommended that AzA be used for at least 6 months continuously for maintenance.[20] Whitening agent Azelaic acid is used for treatment of skin pigmentation, including melasma and postinflammatory hyperpigmentation, particularly in those with darker skin types. It has been recommended as an alternative to hydroquinone.[23] As a tyrosinase inhibitor,[5] azelaic acid reduces synthesis of melanin.[24] According to one report in 1988, azelaic acid in combination with zinc sulfate in vitro was found to be a potent (90\\\% inhibition) 5α-reductase inhibitor, similar to the hair loss drugs finasteride and dutasteride.[25] In vitro research during mid-1980s evaluating azelaic acid's depigmenting (whitening) capability concluded it is effective (cytotoxic to melanocytes) at only high concentrations.[26] A 1996 review claimed 20\\\% AzA is as potent as 4\\\% hydroquinone after a period of application of three months without the latter's adverse effects and even more effective if applied along with tretinoin for the same period of time.[27][19] Azelaic acid is a nine-carbon dicarboxylic acid. Azelaic acid has antimicrobial activity against Propionibacterium acnes and Staphylococcus epidermidis through inhibition of microbial cellular prorein synthesis. Azelaic acid has hypopigmentation action resulting from its ability to scavenge free radicals[1][2]. Azelaic acid is a nine-carbon dicarboxylic acid.

Ergosterol
Ergosterol is a phytosterol consisting of ergostane having double bonds at the 5,6-, 7,8- and 22,23-positions as well as a 3beta-hydroxy group. It has a role as a fungal metabolite and a Saccharomyces cerevisiae metabolite. It is a 3beta-sterol, an ergostanoid, a 3beta-hydroxy-Delta(5)-steroid and a member of phytosterols. A steroid of interest both because its biosynthesis in FUNGI is a target of ANTIFUNGAL AGENTS, notably AZOLES, and because when it is present in SKIN of animals, ULTRAVIOLET RAYS break a bond to result in ERGOCALCIFEROL. Ergosterol is a natural product found in Gladiolus italicus, Ramaria formosa, and other organisms with data available. ergosterol is a metabolite found in or produced by Saccharomyces cerevisiae. A steroid occurring in FUNGI. Irradiation with ULTRAVIOLET RAYS results in formation of ERGOCALCIFEROL (vitamin D2). See also: Reishi (part of). Ergosterol, also known as provitamin D2, belongs to the class of organic compounds known as ergosterols and derivatives. These are steroids containing ergosta-5,7,22-trien-3beta-ol or a derivative thereof, which is based on the 3beta-hydroxylated ergostane skeleton. Thus, ergosterol is considered to be a sterol lipid molecule. Ergosterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Ergosterol is the biological precursor to vitamin D2. It is turned into viosterol by ultraviolet light, and is then converted into ergocalciferol, which is a form of vitamin D. Ergosterol is a component of fungal cell membranes, serving the same function that cholesterol serves in animal cells. Ergosterol is not found in mammalian cell membranes.

Uracil
Uracil, also known as U, 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. Uracil is a common naturally occurring pyrimidine found in RNA. It base pairs with adenine and is replaced by thymine in DNA. Uracil is one of the four nucleobases in RNA that are represented by the letters A, G, C and U. Methylation of uracil produces thymine. The name "uracil" was coined in 1885 by the German chemist Robert Behrend, who was attempting to synthesize derivatives of uric acid. Originally discovered in 1900, uracil was isolated by hydrolysis of yeast nuclein that was found in bovine thymus and spleen, herring sperm, and wheat germ. Uracil exists in all living species, ranging from bacteria to plants to humans. Uracils use in the body is to help carry out the synthesis of many enzymes necessary for cell function through bonding with riboses and phosphates. Uracil serves as an allosteric regulator and a coenzyme for many important biochemical reactions. Uracil (via the nucleoside uridine) can be phosphorylated by various kinases to produce UMP, UDP and UTP. UDP and UTP regulate carbamoyl phosphate synthetase II (CPSase II) activity in animals. Uracil is also involved in the biosynthesis of polysaccharides and in the transport of sugars containing aldehydes. Within humans, uracil participates in a number of enzymatic reactions. In particular, uracil and ribose 1-phosphate can be biosynthesized from uridine; which is mediated by the enzyme uridine phosphorylase 2. In addition, uracil can be converted into dihydrouracil through the action of the enzyme dihydropyrimidine dehydrogenase [NADP(+)]. Uracil is rarely found in DNA, and this may have been an evolutionary change to increase genetic stability. This is because cytosine can deaminate spontaneously to produce uracil through hydrolytic deamination. Therefore, if there were an organism that used uracil in its DNA, the deamination of cytosine (which undergoes base pairing with guanine) would lead to formation of uracil (which would base pair with adenine) during DNA synthesis. Uracil can be used for drug delivery and as a pharmaceutical. When elemental fluorine reacts with uracil, it produces 5-fluorouracil. 5-Fluorouracil is an anticancer drug (antimetabolite) that mimics uracil during the nucleic acid (i.e. RNA) synthesis and transcription process. Because 5-fluorouracil is similar in shape to, but does not undergo the same chemistry as, uracil, the drug inhibits RNA replication enzymes, thereby blocking RNA synthesis and stopping the growth of cancerous cells. Uracil is a common and naturally occurring pyrimidine derivative. Originally discovered in 1900, it was isolated by hydrolysis of yeast nuclein that was found in bovine thymus and spleen, herring sperm, and wheat germ. It is a planar, unsaturated compound that has the ability to absorb light. Uracil. CAS Common Chemistry.

Methyl isobutyl ketone
Methyl isobutyl ketone (MIBK) is an organic solvent. MIBK is among the top ten most popular organic solvents used in industry. MIBK is occasionally found as a volatile component of urine. MIBK in urine is considered as a biological marker of occupational exposure to this solvent. Olfactory perception is significant but adaptation may occur. The typical toxicity effects of MIBK in humans exposed at 50 to 100 ppm are mucous membrane irritation and weak effects on the central nervous system (CNS) such as headache. Visual dysfunction has been reported in workers exposed to a mixture of organic solvents containing MIBK. Memory impairment was detected in clinical observation on a 44-year-old man who had been exposed to MIBK at 100 ppm for more than 10 years. Regarding to the route of absorption, skin penetration of MIBK is substantial. (PMID: 12592578, 17485256, 16464817, 5556886).

Propyl alcohol
Propyl alcohol, also known as 1-propanol, n-propanol, or simply propanol, belongs to the class of organic compounds known as primary alcohols. Primary alcohols are compounds in which a hydroxy group is bonded to a primary carbon, with the general structure RCOH (R=alkyl, aryl). Propyl alcohol is a colourless, volatile liquid that is fully miscible with water. It has a sweet odour and an alcoholic, fermented, fusel taste. Propyl alcohol exists in all living species, ranging from bacteria to plants to humans. Propanol can be produced through fermentation of sugars by bacteria and yeast and small amounts are produced by gut microflora. Propanol has been identified as a fecal biomarker of Clostridium difficile infection (PMID: 30986230). When ingested, 1-propanol is metabolized by alcohol dehydrogenase to propionic acid leading to metabolic acidosis and an elevated anion gap (PMID: 18375643). It can be found in small amounts in alcoholic beverages such as wine. Industrially, the major use of 1-propanol is as a solvent as well as an intermediate in forming other industrially important compounds. It is used as a carrier and extraction solvent for natural products, such as flavourings, vegetable oils, resins, waxes, and gums, and as a solvent for synthetic polymers, such as polyvinyl butyral, cellulose esters, lacquers, and PVC adhesives. Other solvent applications include the use of 1-propanol in the polymerization and spinning of acrylonitrile, in flexographic printing inks, and in the dyeing of wool. 1-Propanol is used for both its solvent and antiseptic properties in drugs and cosmetics, such as lotions, soaps, and nail polishes (IPCS INCHEM, EHC 102). Both 1-propanol and 2-propanol are often used in hand disinfectants as they have excellent bactericidal activity. 1-Propanol is used less in industry than 2-propanol as it is more expensive and it is a toxicant that has a similar taste to ethanol, so 2-propanol is used as its unpleasant smell discourages abuse. Propyl alcohol, also known as propanol or ethylcarbinol, is a member of the class of compounds known as primary alcohols. Primary alcohols are compounds comprising the primary alcohol functional group, with the general structure RCOH (R=alkyl, aryl). Thus, propyl alcohol is considered to be a fatty alcohol lipid molecule. Propyl alcohol is soluble (in water) and an extremely weak acidic compound (based on its pKa). Propyl alcohol can be found in a number of food items such as cashew nut, chinese mustard, greenthread tea, and chayote, which makes propyl alcohol a potential biomarker for the consumption of these food products.

Acetone
Acetone, or propanone, is an organic compound with the formula (CH3)2CO. It is the simplest and smallest ketone. It is a colourless, highly volatile and flammable liquid with a characteristic pungent odour. Acetone is miscible with water and serves as an important organic solvent in its own right, in industry, home, and laboratory. Acetone is produced and disposed of in the human body through normal metabolic processes. It is normally present in blood and urine. People with diabetic ketoacidosis produce it in larger amounts. Acetone is not regarded as a waste product of metabolism. However, its physiological role in biochemical machinery is not clear. A model for the role of acetone metabolism is presented that orders the events occurring in acetonemia in sequence: in diabetic ketosis or starvation, ketone body production (b-hydroxy-butyrate, acetoacetate) provides fuel for vital organs (heart, brain, among others) raising the chance of survival of the metabolic catastrophe. However, when ketone body production exceeds the degrading capacity, the accumulating acetoacetic acid presents a new challenge to the pH regulatory system. Acetone production and its further degradation to C3 fragments fulfill two purposes: the maintenance of pH buffering capacity and provision of fuel for peripheral tissues. Since ketosis develops under serious metabolic circumstances, all the mechanisms that balance or moderate the effects of ketosis enhance the chance for survival. From this point of view, the theory that transportable C3 fragments can serve as additional nutrients is a novel view of acetone metabolism which introduces a new approach to the study of acetone degradation, especially in understanding its physiological function and the interrelationship between liver and peripheral tissues. (PMID 10580530). Acetone is typically derived from acetoacetate through the action of microbial acetoacetate decarboxylases found in gut microflora. In chemistry, acetone is the simplest representative of the ketones. Acetone is a colorless, mobile, flammable liquid readily soluble in water, ethanol, ether, etc., and itself serves as an important solvent. It is an irritant and inhalation may lead to hepatotoxic effects (causing liver damage). Acetone can be found in Clostridium (PMID:685531).

Terpinolene
Terpinolene (TPO), also known as alpha-terpinolene or isoterpinene, belongs to the class of organic compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. Thus, terpinolene is considered to be an isoprenoid lipid molecule. Terpinolene is a very hydrophobic monoterpenoid, practically insoluble in water, and relatively neutral. Monoterpenoids are terpenes that contain 10 carbon atoms and are comprised of two isoprene units. The biosynthesis of monoterpenes in plants 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. Terpinolene is one of the constituents of turpentine and an isomer of terpinene. It appears colourless to pale yellow liquid. Alpha-terpinolene has been identified as an abundant monoterpene in the essential oil of Cannabis sativa plants (PMID:6991645 ). There are more than 140 known terpenes in cannabis and the combination of these terepenoids produces the skunky, fruity odor characteristic of C. savita. Although common in cannabis cultivars, terpinolene is typically found in relatively low amounts. On the other hand, the concentration of terpinolene can be has high as 30\\% of the essential oil. It is thought that terpinolene offers a mildly sedative effect and can reduce anxiety (PMID:28826544 ). In particular, terpinolene is a central nervous system depressant that has been shown to induce drowsiness (PMID:23339024 ). Terpinolene has been demonstrated to prevent LDL oxidation and is of potential interest in the treatment of atherogenesis and coronary artery disease (PMID:28826544 ). Terpinolene exhibits antifungal and larvicidal properties (PMID:28826544 ). Terpinolene is also an effective anti-microbial agent, particularly against E coli and Staphylococcus bacteria (PMID:16402540 ). Terpinolene is also employed as a fragrence ingredient in lotions, insect repellents (similar to other terpenes), perfumes, and soaps. Terpinolene is also a constituent of many other essential oils e. g. Citrus, Mentha, Juniperus, Myristica species. Parsnip oil (Pastinaca sativa) in particular, is a major source (40-70\\%). Terpinolene is a sweet, citrus, and fresh tasting compound. It produces a floral, woody or herbal aroma reminiscent of pine needles. In addition to being found in various plant essential oils, terpinolene is found in a few different foods and spices, such as allspice, apples, sage, rosemary, parsnips, nutmegs, and wild carrots and in a lower concentration in sweet bay, star anises, turmerics, apricots, cumins, evergreen blackberries, red bell peppers, and caraway. Constituent of many essential oils e.g. Citrus, Mentha, Juniperus, Myristica subspecies Parsnip oil (Pastinaca sativa) is a major source (40-70\\%). Flavouring ingredient. Terpinolene is found in many foods, some of which are coriander, ceylon cinnamon, pine nut, and caraway.
Acetaldehyde
Acetaldehyde, also known as ethanal, belongs to the class of organic compounds known as short-chain aldehydes. These are an aldehyde with a chain length containing between 2 and 5 carbon atoms. Acetaldehyde exists in all living species, ranging from bacteria to humans. Within humans, acetaldehyde participates in a number of enzymatic reactions. In particular, acetaldehyde can be biosynthesized from ethanol which is mediated by the enzyme alcohol dehydrogenase 1B. Acetaldehyde can also be converted to acetic acid by the enzyme aldehyde dehydrogenase (mitochondrial) and aldehyde dehydrogenase X (mitochondrial). The main method of production is the oxidation of ethylene by the Wacker process, which involves oxidation of ethylene using a homogeneous palladium/copper system: 2 CH2CH2 + O2 → 2 CH3CHO. In the 1970s, the world capacity of the Wacker-Hoechst direct oxidation process exceeded 2 million tonnes annually. In humans, acetaldehyde is involved in disulfiram action pathway. Acetaldehyde is an aldehydic, ethereal, and fruity tasting compound. Outside of the human body, acetaldehyde is found, on average, in the highest concentration in a few different foods, such as sweet oranges, pineapples, and mandarin orange (clementine, tangerine) and in a lower concentration in . acetaldehyde has also been detected, but not quantified in several different foods, such as malabar plums, malus (crab apple), rose hips, natal plums, and medlars. This could make acetaldehyde a potential biomarker for the consumption of these foods. In condensation reactions, acetaldehyde is prochiral. Acetaldehyde is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Acetaldehyde has been found to be associated with several diseases such as alcoholism, ulcerative colitis, nonalcoholic fatty liver disease, and crohns disease; also acetaldehyde has been linked to the inborn metabolic disorders including aldehyde dehydrogenase deficiency (III) sulfate is used to reoxidize the mercury back to the mercury. Acetaldehyde was first observed by the Swedish pharmacist/chemist Carl Wilhelm Scheele (1774); it was then investigated by the French chemists Antoine François, comte de Fourcroy and Louis Nicolas Vauquelin (1800), and the German chemists Johann Wolfgang Döbereiner (1821, 1822, 1832) and Justus von Liebig (1835). At room temperature, acetaldehyde (CH3CHO) is more stable than vinyl alcohol (CH2CHOH) by 42.7 kJ/mol: Overall the keto-enol tautomerization occurs slowly but is catalyzed by acids. The level at which an average consumer could detect acetaldehyde is still considerably lower than any toxicity. Pathways of exposure include air, water, land, or groundwater, as well as drink and smoke. Acetaldehyde is also created by thermal degradation or ultraviolet photo-degradation of some thermoplastic polymers during or after manufacture. The water industry generally recognizes 20–40 ppb as the taste/odor threshold for acetaldehyde. The level at which an average consumer could detect acetaldehyde is still considerably lower than any toxicity. Flavouring agent and adjuvant used to impart orange, apple and butter flavours; component of food flavourings added to milk products, baked goods, fruit juices, candy, desserts and soft drinks [DFC]
Ethanol
Ethanol is a clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant. It is widely used as a solvent and preservative in pharmaceutical preparations as well as serving as the primary ingredient in alcoholic beverages. Indeed, ethanol has widespread use as a solvent of substances intended for human contact or consumption, including scents, flavorings, colorings, and medicines. Ethanol has a depressive effect on the central nervous system and because of its psychoactive effects, it is considered a drug. Ethanol has a complex mode of action and affects multiple systems in the brain, most notably it acts as an agonist to the GABA receptors. Death from ethanol consumption is possible when blood alcohol level reaches 0.4\\%. A blood level of 0.5\\% or more is commonly fatal. Levels of even less than 0.1\\% can cause intoxication, with unconsciousness often occurring at 0.3-0.4 \\%. Ethanol is metabolized by the body as an energy-providing carbohydrate nutrient, as it metabolizes into acetyl CoA, an intermediate common with glucose metabolism, that can be used for energy in the citric acid cycle or for biosynthesis. Ethanol within the human body is converted into acetaldehyde by alcohol dehydrogenase and then into acetic acid by acetaldehyde dehydrogenase. The product of the first step of this breakdown, acetaldehyde, is more toxic than ethanol. Acetaldehyde is linked to most of the clinical effects of alcohol. It has been shown to increase the risk of developing cirrhosis of the liver,[77] multiple forms of cancer, and alcoholism. Industrially, ethanol is produced both as a petrochemical, through the hydration of ethylene, and biologically, by fermenting sugars with yeast. Small amounts of ethanol are endogenously produced by gut microflora through anaerobic fermentation. However most ethanol detected in biofluids and tissues likely comes from consumption of alcoholic beverages. Absolute ethanol or anhydrous alcohol generally refers to purified ethanol, containing no more than one percent water. Absolute alcohol is not intended for human consumption. It often contains trace amounts of toxic benzene (used to remove water by azeotropic distillation). Consumption of this form of ethanol can be fatal over a short time period. Generally absolute or pure ethanol is used as a solvent for lab and industrial settings where water will disrupt a desired reaction. Pure ethanol is classed as 200 proof in the USA and Canada, equivalent to 175 degrees proof in the UK system. Ethanol is a general biomarker for the consumption of alcohol. Ethanol is also a metabolite of Hansenula and Saccharomyces (PMID: 14613880) (https://ac.els-cdn.com/S0079635206800470/1-s2.0-S0079635206800470-main.pdf?_tid=4d340044-3230-4141-88dd-deec4d2e35bd&acdnat=1550288012_0c4a20fe963843426147979d376cf624).

Anisole
Anisole is a flavouring agent Anisole is a precursor to perfumes, insect pheromones, and pharmaceuticals. For example, synthetic anethole is prepared from anisole. Anisole undergoes electrophilic aromatic substitution reaction more quickly than does benzene, which in turn reacts more quickly than nitrobenzene. The methoxy group is an ortho/para directing group, which means that electrophilic substitution preferentially occurs at these three sites. The enhanced nucleophilicity of anisole vs benzene reflects the influence of the methoxy group, which renders the ring more electron-rich. The methoxy group strongly affects the pi cloud of the ring, moreso than the inductive effect of the electronegative oxygen. Flavouring agent
Dodecanol
Dodecanol, also known as dodecyl alcohol or lorol, is a member of the class of compounds known as fatty alcohols.
