Cinnamaldehyde
(E)-cinnamaldehyde is the E (trans) stereoisomer of cinnamaldehyde, the parent of the class of cinnamaldehydes. It has a role as a hypoglycemic agent, an EC 4.3.1.24 (phenylalanine ammonia-lyase) inhibitor, a vasodilator agent, an antifungal agent, a flavouring agent, a plant metabolite and a sensitiser. It is a 3-phenylprop-2-enal and a member of cinnamaldehydes. Cinnamaldehyde is a naturally occurring flavonoid that gives the spice cinnamon its flavour and odour. It occurs naturally in the bark of cinnamon trees and other species of the genus Cinnamomum such as camphor and cassia. Sensitivity to cinnamaldehyde may be identified with a clinical patch test. Cinnamaldehyde is a Standardized Chemical Allergen. The physiologic effect of cinnamaldehyde is by means of Increased Histamine Release, and Cell-mediated Immunity. Cinnamaldehyde is a natural product found in Chaerophyllum bulbosum, Cinnamomum sieboldii, and other organisms with data available. Cinnamaldehyde is the aldehyde that gives cinnamon its flavor and odor. Cinnamaldehyde occurs naturally in the bark of cinnamon trees and other species of the genus Cinnamomum like camphor and cassia. These trees are the natural source of cinnamon, and the essential oil of cinnamon bark is about 90\\\\% cinnamaldehyde. Cinnamaldehyde is also used as a fungicide. Proven effective on over 40 different crops, cinnamaldehyde is typically applied to the root systems of plants. Its low toxicity and well-known properties make it ideal for agriculture. To a lesser extent, cinnamaldehyde is an effective insecticide, and its scent is also known to repel animals like cats and dogs. Cinnamaldehyde is also known as a corrosion inhibitor for steel and other ferrous alloys in corrosive fluids. It can be used in combination with additional components such as dispersing agents, solvents and other surfactants. Concentrated cinnamaldehyde is a skin irritant, and the chemical is toxic in large doses, but no agencies suspect the compound is a carcinogen or poses a long-term health hazard. Most cinnamaldehyde is excreted in urine as cinnamic acid, an oxidized form of cinnamaldehyde. Cinnamaldehyde is a metabolite found in or produced by Saccharomyces cerevisiae. Cinnamaldehyde, also known as (E)-3-phenyl-2-propenal or 3-phenylacrylaldehyde, is a member of the class of compounds known as cinnamaldehydes. Cinnamaldehydes are organic aromatic compounds containing a cinnamlaldehyde moiety, consisting of a benzene and an aldehyde group to form 3-phenylprop-2-enal. Cinnamaldehyde is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Cinnamaldehyde is a sweet, candy, and cinnamon tasting compound and can be found in a number of food items such as sour cherry, rubus (blackberry, raspberry), horseradish, and sea-buckthornberry, which makes cinnamaldehyde a potential biomarker for the consumption of these food products. Cinnamaldehyde can be found primarily in feces, as well as in human neuron and skin tissues. Cinnamaldehyde exists in all eukaryotes, ranging from yeast to humans. Cinnamaldehyde is a non-carcinogenic (not listed by IARC) potentially toxic compound. Cinnamaldehyde is an organic compound with the formula C6H5CH=CHCHO. Occurring naturally as predominantly the trans (E) isomer, it gives cinnamon its flavor and odor. It is a flavonoid that is naturally synthesized by the shikimate pathway. This pale yellow, viscous liquid occurs in the bark of cinnamon trees and other species of the genus Cinnamomum. The essential oil of cinnamon bark is about 50\\\\% cinnamaldehyde .

3-ureidopropionate
Ureidopropionic acid, also known as 3-ureidopropanoate or N-carbamoyl-beta-alanine, belongs to the class of organic compounds known as ureas. Ureas are compounds containing two amine groups joined by a carbonyl (C=O) functional group. Ureidopropionic acid is an intermediate in the metabolism of uracil. More specifically, it is a breakdown product of dihydrouracil and is produced by the enzyme dihydropyrimidase. It is further decomposed into beta-alanine via the enzyme beta-ureidopropionase. Ureidopropionic acid is essentially a urea derivative of beta-alanine. High levels of ureidopropionic acid are found in individuals with beta-ureidopropionase (UP) deficiency (PMID: 11675655). Enzyme deficiencies in pyrimidine metabolism are associated with a risk for severe toxicity against the antineoplastic agent 5-fluorouracil. Ureidopropionic acid has been detected, but not quantified in, several different foods, such as gram beans, broccoli, climbing beans, oriental wheat, and mandarin orange (clementine, tangerine). This could make ureidopropionic acid a potential biomarker for the consumption of these foods. N-Carbamoyl-β-alanine. CAS Common Chemistry.

Asparagine
Asparagine (Asn) or L-asparagine is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. L-asparagine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Asparagine is found in all organisms ranging from bacteria to plants to animals. In humans, asparagine is not an essential amino acid, which means that it can be synthesized from central metabolic pathway intermediates in humans and is not required in the diet. The precursor to asparagine is oxaloacetate. Oxaloacetate is converted to aspartate using a transaminase enzyme. This enzyme transfers the amino group from glutamate to oxaloacetate producing alpha-ketoglutarate and aspartate. The enzyme asparagine synthetase produces asparagine, AMP, glutamate, and pyrophosphate from aspartate, glutamine, and ATP. In the asparagine synthetase reaction, ATP is used to activate aspartate, forming beta-aspartyl-AMP. Glutamine donates an ammonium group which reacts with beta-aspartyl-AMP to form asparagine and free AMP. Since the asparagine side chain can make efficient hydrogen bond interactions with the peptide backbone, asparagines are often found near the beginning and end of alpha-helices, and in turn motifs in beta sheets. Its role can be thought as "capping" the hydrogen bond interactions which would otherwise need to be satisfied by the polypeptide backbone. Asparagine also provides key sites for N-linked glycosylation, a modification of the protein chain that is characterized by the addition of carbohydrate chains. A reaction between asparagine and reducing sugars or reactive carbonyls produces acrylamide (acrylic amide) in food when heated to sufficient temperature (i.e. baking). These occur primarily in baked goods such as French fries, potato chips, and roasted coffee. Asparagine was first isolated in 1806 from asparagus juice --hence its name. Asparagine was the first amino acid to be isolated. The smell observed in the urine of some individuals after the consumption of asparagus is attributed to a byproduct of the metabolic breakdown of asparagine, asparagine-amino-succinic-acid monoamide. However, some scientists disagree and implicate other substances in the smell, especially methanethiol. [Spectral] L-Asparagine (exact mass = 132.05349) and L-Aspartate (exact mass = 133.03751) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX.

Glycylglycine
The simplest peptide, made of two glycine molecules; used in the synthesis of more complicated peptides. Glycine is a simple, nonessential amino acid, although experimental animals show reduced growth on low-glycine diets. The average adult ingests 3 to 5 grams of glycine daily. Glycine is involved in the bodys production of DNA, phospholipids and collagen, and in release of energy. Glycine levels are effectively measured in plasma in both normal patients and those with inborn errors of glycine metabolism. (http://www.dcnutrition.com/AminoAcids/) Nonketotic hyperglycinaemia (OMIM 606899) is an autosomal recessive condition caused by deficient enzyme activity of the glycine cleavage enzyme system (EC 2.1.1.10). The glycine cleavage enzyme system comprises four proteins: P-, T-, H- and L-proteins (EC 1.4.4.2, EC 2.1.2.10 and EC 1.8.1.4 for P-, T- and L-proteins). Mutations have been described in the GLDC (OMIM 238300), AMT (OMIM 238310), and GCSH (OMIM 238330) genes encoding the P-, T-, and H-proteins respectively. The glycine cleavage system catalyses the oxidative conversion of glycine into carbon dioxide and ammonia, with the remaining one-carbon unit transferred to folate as methylenetetrahydrofolate. It is the main catabolic pathway for glycine and it also contributes to one-carbon metabolism. Patients with a deficiency of this enzyme system have increased glycine in plasma, urine and cerebrospinal fluid (CSF) with an increased CSF: plasma glycine ratio.

6-Hydroxyhexanoic acid
6-Hydroxyhexanoate was identified as the immediate product of hexanoate w-hydroxylation by whole cells and was further oxidized into adipic acid and an unexpected metabolite identified as 2-tetrahydrofuranacetic acid. This same metabolite, together with adipic acid, was also detected when similarly induced cells were incubated with hexanoate or 1,6-hexanediol, but not with 6-oxohexanoate (adipic semialdehyde).Cells grown on hexanoate and incubated with 6-hydroxyhexanoate were also found to accumulate 2-tetrahydrofuranacetic acid, which was not further degraded. Utilization of 6-hydroxyhexanoate for growth was restricted to those organisms also able to utilize adipate. Similar observations were made with 1,6-hexanediol serving as the carbon source and cells obtained from one organism,Pseudomonas aeruginosa PAO, grown either on 1,6-hexanediol or 6-hydroxyhexanoate,were found to be well induced for both 6-oxohexanoate and adipate oxidation. The results indicate that 6-hydroxyhexanoate and 1,6-hexanediol are susceptible to both 1B- and w-oxidative attack; however, the former pathway appears to be of no physiological significance since it generates 2-tetrahydrofuranacetic acid as a nonmetabolizable intermediate, making w-oxidation via adipate the exclusive pathway for degradation.

Glutaric acid
Glutaric acid is a simple five-carbon linear dicarboxylic acid. Glutaric acid is naturally produced in the body during the metabolism of some amino acids, including lysine and tryptophan. Glutaric acid may cause irritation to the skin and eyes. When present in sufficiently high levels, glutaric acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of glutaric acid are associated with at least three inborn errors of metabolism, including glutaric aciduria type I, malonyl-CoA decarboxylase deficiency, and glutaric aciduria type III. Glutaric aciduria type I (glutaric acidemia type I, glutaryl-CoA dehydrogenase deficiency, GA1, or GAT1) is an inherited disorder in which the body is unable to completely break down the amino acids lysine, hydroxylysine, and tryptophan due to a deficiency of mitochondrial glutaryl-CoA dehydrogenase (EC 1.3.99.7, GCDH). Excessive levels of their intermediate breakdown products (e.g. glutaric acid, glutaryl-CoA, 3-hydroxyglutaric acid, glutaconic acid) can accumulate and cause damage to the brain (and also other organs). Babies with glutaric acidemia type I are often born with unusually large heads (macrocephaly). Macrocephaly is amongst the earliest signs of GA1. GA1 also causes secondary carnitine deficiency because glutaric acid, like other organic acids, is detoxified by carnitine. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of untreated glutaric aciduria. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. Treatment of glutaric aciduria is mainly based on the restriction of lysine intake, supplementation of carnitine, and an intensification of therapy during intercurrent illnesses. The major principle of dietary treatment is to reduce the production of glutaric acid and 3-hydroxyglutaric acid by restriction of natural protein, in general, and of lysine, in particular (PMID: 17465389, 15505398). Glutaric acid has also been found in Escherichia (PMID: 30143200). Isolated from basidiomycete fungi and fruits of Prunus cerasus (CCD). Glutaric acid is found in many foods, some of which are red beetroot, common beet, soy bean, and tamarind. Glutaric acid, C5 dicarboxylic acid, is an intermediate during the catabolic pathways of lysine and tryptophan. Glutaric acid affects pericyte contractility and migration. Glutaric acid is an indicator of glutaric aciduria type I[1][2][3]. Glutaric acid, C5 dicarboxylic acid, is an intermediate during the catabolic pathways of lysine and tryptophan.

In the butanoate metabolism pathway, 2-Acetolactate is created from 2-(alpha-Hydroxyethyl)thiamine diphosphate by acetolactate synthase [EC:2.2.1.6]. 2-Acetolactate is then converted to (R)-Acetoin by acetolactate decarboxylase [EC:4.1.1.5]. In the pantothenate and CoA pathway, 2-Acetolactate is irreversibly created from pyruvate by acetolactate synthase [EC:2.2.1.6]. 2-Acetolactate is then irreversibly converted to 2,3-Dihydroxy-3-methylbutanoate by ketol-acid reductoisomerase [EC:1.1.1.86]. 2-Acetolactate is involved in the butanoate metabolism and pantothenate and CoA biosynthesis pathways.
N-Carbamoylsarcosine
N-Carbamoylsarcosine is an intermediate in arginine and proline metabolism. It is also involved in a metabolic pathway for the degradation of creatinine. In this pathway, creatinine is not hydrolyzed back to creatine. Instead, it is deaminated to N-methylhydantoin, releasing an amonia molecule, by the action of creatinine deaminase (also known as creatinine iminohydrolase). N-methylhydantoin is then hydrolyzed to N-carbamoylsarcosine, by the action of N-methylhydantoin amidohydrolase, at the expense of one ATP molecule. N-carbamoylsarcosine is deaminated further to sarcosine by N-carbamoylsarcosine amidohydrolase, releasing a second ammonia molecule. In the last step of this pathway, sarcosine is hydrolyzed to glycine and formaldehyde, by either sarcosine dehydrogenase or sarcosine oxidase.

Ethylmalonate
Ethylmalonic acid, also known as alpha-carboxybutyric acid or ethylmalonate, is a member of the class of compounds known as branched fatty acids. Branched fatty acids are fatty acids containing one or more branched chains. Ethylmalonic acid is soluble (in water) and a moderately acidic compound (based on its pKa). Ethylmalonic acid can be synthesized from malonic acid, and can be synthesized into (S)-ethylmalonyl-CoA and (R)-ethylmalonyl-CoA. Ethylmalonic acid can be found in blood, cerebrospinal fluid (CSF), and urine, as well as in human fibroblasts, prostate, and skeletal muscle tissues. Moreover, ethylmalonic acid is found to be associated with anorexia nervosa and malonyl-CoA decarboxylase deficiency. Ethylmalonic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Chronically high levels of ethylmalonic acid are associated with at least two inborn errors of metabolism, including short-chain acyl-CoA dehydrogenase deficiency (SCAD deficiency) and ethylmalonic encephalopathy. Ethylmalonic acid is identified in the urine of patients with short-chain acyl-CoA dehydrogenase deficiency, which is a fatty acid metabolism disorder. When present at sufficiently high levels, ethylmalonic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Ethylmalonic acid is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart abnormalities, kidney abnormalities, liver damage, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. Ethylmalonic acid is identified in the urine of patients with short-chain acyl-coenzyme A dehydrogenase deficiency, which is a fatty acid metabolism disorder. [HMDB] Ethylmalonic acid is non-carcinogenic potentially toxic and associated with anorexia nervosa and malonyl-CoA decarboxylase deficiency.

Alitretinoin inhibits the growth of Kaposis sarcoma (KS) cells in vitro. Retinoic acid is the oxidized form of Vitamin A. It functions in determining position along embryonic anterior/posterior axis in chordates. It acts through Hox genes, which ultimately control anterior/posterior patterning in early developmental stages.
