L-Tryptophan
Tryptophan (Trp) or L-tryptophan 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-tryptophan is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Tryptophan is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aromatic amino acid. Tryptophan is an essential amino acid, meaning the body cannot synthesize it, and it must be obtained from the diet. The requirement for tryptophan and protein decreases with age. The minimum daily requirement for adults is 3 mg/kg/day or about 200 mg a day. There is 400 mg of tryptophan in a cup of wheat germ. A cup of low-fat cottage cheese contains 300 mg of tryptophan and chicken and turkey contain up to 600 mg of tryptophan per pound (http://www.dcnutrition.com). Tryptophan is particularly plentiful in chocolate, oats, dried dates, milk, yogurt, cottage cheese, red meat, eggs, fish, poultry, sesame, chickpeas, almonds, sunflower seeds, pumpkin seeds, buckwheat, spirulina, and peanuts. Tryptophan is the precursor of both serotonin and melatonin. Melatonin is a hormone that is produced by the pineal gland in animals, which regulates sleep and wakefulness. Serotonin is a brain neurotransmitter, platelet clotting factor, and neurohormone found in organs throughout the body. Metabolism of tryptophan into serotonin requires nutrients such as vitamin B6, niacin, and glutathione. Niacin (also known as vitamin B3) is an important metabolite of tryptophan. It is synthesized via kynurenine and quinolinic acids, which are products of tryptophan degradation. There are a number of conditions or diseases that are characterized by tryptophan deficiencies. For instance, fructose malabsorption causes improper absorption of tryptophan in the intestine, which reduces levels of tryptophan in the blood and leads to depression. High corn diets or other tryptophan-deficient diets can cause pellagra, which is a niacin-tryptophan deficiency disease with symptoms of dermatitis, diarrhea, and dementia. Hartnups disease is a disorder in which tryptophan and other amino acids are not absorbed properly. Symptoms of Hartnups disease include skin rashes, difficulty coordinating movements (cerebellar ataxia), and psychiatric symptoms such as depression or psychosis. Tryptophan supplements may be useful for treating Hartnups disease. Assessment of tryptophan deficiency is done through studying excretion of tryptophan metabolites in the urine or blood. Blood may be the most sensitive test because the amino acid tryptophan is transported in a unique way. Increased urination of tryptophan breakdown products (such as kynurenine) correlates with increased tryptophan degradation, which occurs with oral contraception, depression, mental retardation, hypertension, and anxiety states. Tryptophan plays a role in "feast-induced" drowsiness. Ingestion of a meal rich in carbohydrates triggers the release of insulin. Insulin, in turn, stimulates the uptake of large neutral branched-chain amino acids (BCAAs) into muscle, increasing the ratio of tryptophan to BCAA in the bloodstream. The increased tryptophan ratio reduces competition at the large neutral amino acid transporter (which transports both BCAAs and tryptophan), resulting in greater uptake of tryptophan across the blood-brain barrier into the cerebrospinal fluid (CSF). Once in the CSF, tryptophan is converted into serotonin and the resulting serotonin is further metabolized into melatonin by the pineal gland, which promotes sleep. Because tryptophan is converted into 5-hydroxytryptophan (5-HTP) which is then converted into the neurotransmitter serotonin, it has been proposed th... L-tryptophan is a white powder with a flat taste. An essential amino acid; occurs in isomeric forms. (NTP, 1992) L-tryptophan is the L-enantiomer of tryptophan. It has a role as an antidepressant, a nutraceutical, a micronutrient, a plant metabolite, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is an erythrose 4-phosphate/phosphoenolpyruvate family amino acid, a proteinogenic amino acid, a tryptophan and a L-alpha-amino acid. It is a conjugate base of a L-tryptophanium. It is a conjugate acid of a L-tryptophanate. It is an enantiomer of a D-tryptophan. It is a tautomer of a L-tryptophan zwitterion. An essential amino acid that is necessary for normal growth in infants and for nitrogen balance in adults. It is a precursor of indole alkaloids in plants. It is a precursor of serotonin (hence its use as an antidepressant and sleep aid). It can be a precursor to niacin, albeit inefficiently, in mammals. L-Tryptophan is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Tryptophan is the least plentiful of all 22 amino acids and an essential amino acid in humans (provided by food), Tryptophan is found in most proteins and a precursor of serotonin. Tryptophan is converted to 5-hydroxy-tryptophan (5-HTP), converted in turn to serotonin, a neurotransmitter essential in regulating appetite, sleep, mood, and pain. Tryptophan is a natural sedative and present in dairy products, meats, brown rice, fish, and soybeans. (NCI04) Tryptophan is an essential amino acid which is the precursor of serotonin. Serotonin is a brain neurotransmitter, platelet clotting factor and neurohormone found in organs throughout the body. Metabolism of tryptophan to serotonin requires nutrients such as vitamin B6, niacin and glutathione. Niacin is an important metabolite of tryptophan. High corn or other tryptophan-deficient diets can cause pellagra, which is a niacin-tryptophan deficiency disease with symptoms of dermatitis, diarrhea and dementia. Inborn errors of tryptophan metabolism exist where a tumor (carcinoid) makes excess serotonin. Hartnups disease is a disease where tryptophan and other amino acids are not absorbed properly. Tryptophan supplements may be useful in each condition, in carcinoid replacing the over-metabolized nutrient and in Hartnups supplementing a malabsorbed nutrient. Some disorders of excess tryptophan in the blood may contribute to mental retardation. Assessment of tryptophan deficiency is done through studying excretion of tryptophan metabolites in the urine or blood. Blood may be the most sensitive test because the amino acid tryptophan is transported in a unique way. Increased urination of tryptophan fragments correlates with increased tryptophan degradation, which occurs with oral contraception, depression, mental retardation, hypertension and anxiety states. The requirement for tryptophan and protein decreases with age. Adults minimum daily requirement is 3 mg/kg/day or about 200 mg a day. This may be an underestimation, for there are 400 mg of tryptophan in just a cup of wheat germ.

Cholic acid
Cholic acid is a bile acid that is 5beta-cholan-24-oic acid bearing three alpha-hydroxy substituents at position 3, 7 and 12. It has a role as a human metabolite and a mouse metabolite. It is a bile acid, a C24-steroid, a 3alpha-hydroxy steroid, a 7alpha-hydroxy steroid, a 12alpha-hydroxy steroid and a trihydroxy-5beta-cholanic acid. It is a conjugate acid of a cholate. Cholic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Cholic acid is a Bile Acid. Cholic acid is a naturally occurring bile acid that is used to treat patients with genetic deficiencies in the synthesis of bile acids. When given in high doses, cholic acid replacement therapy has been linked to minor elevations in serum aminotransferase levels, but it has not been linked to instances of clinically apparent acute liver injury with jaundice. Cholic acid is a natural product found in Caenorhabditis elegans, Bufo bufo, and Homo sapiens with data available. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion. Bile acids are steroid acids found predominantly in bile of mammals. The distinction between different bile acids is minute, depends only on presence or absence of hydroxyl groups on positions 3, 7, and 12. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. Bile acids have potent toxic properties (e.g., membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues. (A3407, A3408, A3409, A3410).

When present in sufficiently high levels, cholic acid can act as a hepatotoxin and a metabotoxin. A hepatotoxin causes damage to the liver or liver cells. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Among the primary bile acids, cholic acid is considered to be the least hepatotoxic while deoxycholic acid is the most hepatoxic (PMID: 1641875). The liver toxicity of bile acids appears to be due to their ability to peroxidate lipids and to lyse liver cells. Chronically high levels of cholic acid are associated with familial hypercholanemia. In hypercholanemia, bile acids, including cholic acid, are elevated in the blood. This disease causes liver damage, extensive itching, poor fat absorption, and can lead to rickets due to lack of calcium in bones. The deficiency of normal bile acids in the intestines results in a deficiency of vitamin K, which also adversely affects clotting of the blood. The bile acid ursodiol (ursodeoxycholic acid) can improve symptoms associated with familial hypercholanemia. Cholic acid. CAS Common Chemistry.

L-Tyrosine
Tyrosine (Tyr) or L-tyrosine 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-tyrosine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Tyrosine is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aromatic amino acid. Tyrosine is a non-essential amino acid, meaning the body can synthesize it – usually from phenylalanine. The conversion of phenylalanine to tyrosine is catalyzed by the enzyme phenylalanine hydroxylase, a monooxygenase. This enzyme catalyzes the reaction causing the addition of a hydroxyl group to the end of the 6-carbon aromatic ring of phenylalanine, such that it becomes tyrosine. Tyrosine is found in many high-protein food products such as chicken, turkey, fish, milk, yogurt, cottage cheese, cheese, peanuts, almonds, pumpkin seeds, sesame seeds, soy products, lima beans, avocados and bananas. Tyrosine is one of the few amino acids that readily passes the blood-brain barrier. Once in the brain, it is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, better known as adrenalin. These neurotransmitters are an important part of the bodys sympathetic nervous system, and their concentrations in the body and brain are directly dependent upon dietary tyrosine. Tyrosine is not found in large concentrations throughout the body, probably because it is rapidly metabolized. Folic acid, copper and vitamin C are cofactor nutrients of these reactions. Tyrosine is also the precursor for hormones, including thyroid hormones (diiodotyrosine), catecholestrogens and the major human pigment, melanin. Tyrosine is an important amino acid in many proteins, peptides and even enkephalins, the bodys natural pain reliever. Valine and other branched amino acids, and possibly tryptophan and phenylalanine may reduce tyrosine absorption. A number of genetic errors of tyrosine metabolism have been identified, such as hawkinsinuria and tyrosinemia I. The most common feature of these diseases is the increased amount of tyrosine in the blood, which is marked by decreased motor activity, lethargy and poor feeding. Infection and intellectual deficits may occur. Vitamin C supplements can help reverse these disease symptoms. Some adults also develop elevated tyrosine in their blood. This typically indicates a need for more vitamin C. More tyrosine is needed under stress, and tyrosine supplements prevent the stress-induced depletion of norepinephrine and can help aleviate biochemical depression. However, tyrosine may not be good for treating psychosis. Many antipsychotic medications apparently function by inhibiting tyrosine metabolism. L-Dopa, which is directly used in Parkinsons, is made from tyrosine. Tyrosine, the nutrient, can be used as an adjunct in the treatment of Parkinsons. Peripheral metabolism of tyrosine necessitates large doses of tyrosine, however, compared to L-Dopa (http://www.dcnutrition.com). In addition to its role as a precursor for neurotransmitters, tyrosine plays an important role for the function of many proteins. Within many proteins or enzymes, certain tyrosine residues can be tagged (at the hydroxyl group) with a phosphate group (phosphorylated) by specialized protein kinases. In its phosphorylated form, tyrosine is called phosphotyrosine. Tyrosine phosphorylation is considered to be one of the key steps in signal transduction and regulation of enzymatic activity. Tyrosine (or its precursor phenylalanine) is also needed to synthesize the benzoquinone structure which forms part of coenzyme Q10. L-tyrosine is an optically active form of tyrosine having L-configuration. It has a role as an EC 1.3.1.43 (arogenate dehydrogenase) inhibitor, a nutraceutical, a micronutrient and a fundamental metabolite. It is an erythrose 4-phosphate/phosphoenolpyruvate family amino acid, a proteinogenic amino acid, a tyrosine and a L-alpha-amino acid. It is functionally related to a L-tyrosinal. It is a conjugate base of a L-tyrosinium. It is a conjugate acid of a L-tyrosinate(1-). It is an enantiomer of a D-tyrosine. It is a tautomer of a L-tyrosine zwitterion. Tyrosine is a non-essential amino acid. In animals it is synthesized from [phenylalanine]. It is also the precursor of [epinephrine], thyroid hormones, and melanin. L-Tyrosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). L-Tyrosine is the levorotatory isomer of the aromatic amino acid tyrosine. L-tyrosine is a naturally occurring tyrosine and is synthesized in vivo from L-phenylalanine. It is considered a non-essential amino acid; however, in patients with phenylketonuria who lack phenylalanine hydroxylase and cannot convert phenylalanine into tyrosine, it is considered an essential nutrient. In vivo, tyrosine plays a role in protein synthesis and serves as a precursor for the synthesis of catecholamines, thyroxine, and melanin.

Melatonin
Melatonin is a member of the class of acetamides that is acetamide in which one of the hydrogens attached to the nitrogen atom is replaced by a 2-(5-methoxy-1H-indol-3-yl)ethyl group. It is a hormone secreted by the pineal gland in humans. It has a role as a hormone, an anticonvulsant, an immunological adjuvant, a radical scavenger, a central nervous system depressant, a human metabolite, a mouse metabolite and a geroprotector. It is a member of acetamides and a member of tryptamines. It is functionally related to a tryptamine. Melatonin is a biogenic amine that is found in animals, plants and microbes. Aaron B. Lerner of Yale University is credited for naming the hormone and for defining its chemical structure in 1958. In mammals, melatonin is produced by the pineal gland. The pineal gland is small endocrine gland, about the size of a rice grain and shaped like a pine cone (hence the name), that is located in the center of the brain (rostro-dorsal to the superior colliculus) but outside the blood-brain barrier. The secretion of melatonin increases in darkness and decreases during exposure to light, thereby regulating the circadian rhythms of several biological functions, including the sleep-wake cycle. In particular, melatonin regulates the sleep-wake cycle by chemically causing drowsiness and lowering the body temperature. Melatonin is also implicated in the regulation of mood, learning and memory, immune activity, dreaming, fertility and reproduction. Melatonin is also an effective antioxidant. Most of the actions of melatonin are mediated through the binding and activation of melatonin receptors. Individuals with autism spectrum disorders (ASD) may have lower than normal levels of melatonin. A 2008 study found that unaffected parents of individuals with ASD also have lower melatonin levels, and that the deficits were associated with low activity of the ASMT gene, which encodes the last enzyme of melatonin synthesis. Reduced melatonin production has also been proposed as a likely factor in the significantly higher cancer rates in night workers. Melatonin is a hormone produced by the pineal gland that has multiple effects including somnolence, and is believed to play a role in regulation of the sleep-wake cycle. Melatonin is available over-the-counter and is reported to have beneficial effects on wellbeing and sleep. Melatonin has not been implicated in causing serum enzyme elevations or clinically apparent liver injury. Melatonin is a natural product found in Mesocricetus auratus, Ophiopogon japonicus, and other organisms with data available. Therapeutic Melatonin is a therapeutic chemically synthesized form of the pineal indole melatonin with antioxidant properties. The pineal synthesis and secretion of melatonin, a serotonin-derived neurohormone, is dependent on beta-adrenergic receptor function. Melatonin is involved in numerous biological functions including circadian rhythm, sleep, the stress response, aging, and immunity. Melatonin is a hormone involved in sleep regulatory activity, and a tryptophan-derived neurotransmitter, which inhibits the synthesis and secretion of other neurotransmitters such as dopamine and GABA. Melatonin is synthesized from serotonin intermediate in the pineal gland and the retina where the enzyme 5-hydroxyindole-O-methyltransferase, that catalyzes the last step of synthesis, is found. This hormone binds to and activates melatonin receptors and is involved in regulating the sleep and wake cycles. In addition, melatonin possesses antioxidative and immunoregulatory properties via regulating other neurotransmitters. Melatonin is a biogenic amine that is found in animals, plants and microbes. Aaron B. Lerner of Yale University is credited for naming the hormone and for defining its chemical structure in 1958. In mammals, melatonin is produced by the pineal gland.

L-Leucine
Leucine (Leu) or L-leucine 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 (‚ÄìNH2) and carboxyl (‚ÄìCOOH) functional groups, along with a side chain (R group) specific to each amino acid. L-leucine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Leucine is found in all organisms ranging from bacteria to plants to animals. It is classified as a non-polar, uncharged (at physiological pH) aliphatic amino acid. Leucine is essential in humans, meaning the body cannot synthesize it, and it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, beans and legumes. L-Leucine is a branched chain amino acid (BCAA). The BCAAs consist of leucine, valine and isoleucine (and occasionally threonine). BCAAs are essential amino acids whose carbon structure is marked by a branch point at the beta-carbon position. BCAAs are critical to human life and are particularly involved in stress, energy and muscle metabolism. BCAA supplementation as therapy, both oral and intravenous, in human health and disease holds great promise. BCAAs have different metabolic routes, with valine going solely to carbohydrates (glucogenic), leucine solely to fats (ketogenic) and isoleucine being both a glucogenic and a ketogenic amino acid. The different metabolism accounts for different requirements for these essential amino acids in humans: 12 mg/kg, 14 mg/kg and 16 mg/kg of valine, leucine and isoleucine respectively. The primary metabolic end products of leucine metabolism are acetyl-CoA and acetoacetate; consequently, it is one of the two exclusively ketogenic amino acids, with lysine being the other. Leucine is the most important ketogenic amino acid in humans. The vast majority of l-leucine metabolism is initially catalyzed by the branched-chain amino acid aminotransferase enzyme, producing alpha-ketoisocaproate (alpha-KIC). alpha-KIC is metabolized by the mitochondrial enzyme branched-chain alpha-ketoacid dehydrogenase, which converts it to isovaleryl-CoA. Isovaleryl-CoA is subsequently metabolized by the enzyme isovaleryl-CoA dehydrogenase and converted to beta-methylcrotonyl-CoA (MC-CoA), which is used in the synthesis of acetyl-CoA and other compounds. During biotin deficiency, HMB can be synthesized from MC-CoA via enoyl-CoA hydratase and an unknown thioesterase enzyme, which convert MC-CoA into HMB-CoA and HMB-CoA into HMB respectively. Leucine has the capacity to directly stimulate myofibrillar muscle protein synthesis (PMID 15051860). This effect of leucine arises results from its role as an activator of the mechanistic target of rapamycin (mTOR) (PMID 23551944) a serine-threonine protein kinase that regulates protein biosynthesis and cell growth. The activation of mTOR by leucine is mediated through Rag GTPases. Leucine, like other BCAAs, is associated with insulin resistance. In particular, higher levels of leucine are observed in the blood of diabetic mice, rats, and humans (PMID 25287287). BCAAs such as leucine have different deficiency symptoms. Valine deficiency is marked by neurological defects in the brain, while isoleucine deficiency is marked by muscle tremors. Persistently low leucine levels can result in decreased appetite, poor feeding, lethargy, poor growth, weight loss, skin rashes, hair loss, and desquamation. Many types of inborn errors of BCAA metabolism exist and these are marked by various abnormalities. The most common form is maple syrup urine disease, marked by a characteristic urinary odor.

L-Phenylalanine
Phenylalanine (Phe), also known as L-phenylalanine 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 (‚ÄìNH2) and carboxyl (‚ÄìCOOH) functional groups, along with a side chain (R group) specific to each amino acid. L-phenylalanine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Phenylalanine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aromatic, non-polar amino acid. In humans, phenylalanine is an essential amino acid and the precursor of the amino acid tyrosine. Like tyrosine, phenylalanine is also a precursor for catecholamines including tyramine, dopamine, epinephrine, and norepinephrine. Catecholamines are neurotransmitters that act as adrenalin-like substances. Interestingly, several psychotropic drugs (mescaline, morphine, codeine, and papaverine) also have phenylalanine as a constituent. Phenylalanine is highly concentrated in the human brain and plasma. Normal metabolism of phenylalanine requires biopterin, iron, niacin, vitamin B6, copper, and vitamin C. An average adult ingests 5 g of phenylalanine per day and may optimally need up to 8 g daily. Phenylalanine is highly concentrated in a number of high protein foods, such as meat, cottage cheese, and wheat germ. An additional dietary source of phenylalanine is artificial sweeteners containing aspartame (a methyl ester of the aspartic acid/phenylalanine dipeptide). As a general rule, aspartame should be avoided by phenylketonurics and pregnant women. When present in sufficiently high levels, phenylalanine can act as a neurotoxin and a metabotoxin. A neurotoxin is a compound that disrupts or attacks neural cells and neural tissue. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of phenylalanine are associated with at least five inborn errors of metabolism, including Hartnup disorder, hyperphenylalaninemia due to guanosine triphosphate cyclohydrolase deficiency, phenylketonuria (PKU), tyrosinemia type 2 (or Richner-Hanhart syndrome), and tyrosinemia type III (TYRO3). Phenylketonurics have elevated serum plasma levels of phenylalanine up to 400 times normal. High plasma concentrations of phenylalanine influence the blood-brain barrier transport of large neutral amino acids. The high plasma phenylalanine concentrations increase phenylalanine entry into the brain and restrict the entry of other large neutral amino acids (PMID: 19191004). Phenylalanine has been found to interfere with different cerebral enzyme systems. Untreated phenylketonuria (PKU) can lead to intellectual disability, seizures, behavioural problems, and mental disorders. It may also result in a musty smell and lighter skin. Classic PKU dramatically affects myelination and white matter tracts in untreated infants; this may be one major cause of neurological disorders associated with phenylketonuria. Mild phenylketonuria can act as an unsuspected cause of hyperactivity, learning problems, and other developmental problems in children. It has been recently suggested that PKU may resemble amyloid diseases, such as Alzheimers disease and Parkinsons disease, due to the formation of toxic amyloid-like assemblies of phenylalanine (PMID: 22706200). Phenylalanine also has some potential benefits. Phenylalanine can act as an effective pain reliever. Its use in premenstrual syndrome and Parkinsons may enhance the effects of acupuncture and electric transcutaneous nerve stimulation (TENS). Phenylalanine and tyrosine, like L-DOPA, produce a catecholamine-like effect. Phenylalanine is better absorbed than tyrosine and may cause fewer headaches. Low phenylalanine diets have been prescribed for certain cancers with mixed results. For instance, some tumours use more phen... L-phenylalanine is an odorless white crystalline powder.

It is an erythrose 4-phosphate/phosphoenolpyruvate family amino acid, a proteinogenic amino acid, a phenylalanine and a L-alpha-amino acid. It is a conjugate base of a L-phenylalaninium. It is a conjugate acid of a L-phenylalaninate. It is an enantiomer of a D-phenylalanine. It is a tautomer of a L-phenylalanine zwitterion. Phenylalanine is an essential aromatic amino acid that is a precursor of melanin, [dopamine], [noradrenalin] (norepinephrine), and [thyroxine]. L-Phenylalanine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Phenylalanine is an essential aromatic amino acid in humans (provided by food), Phenylalanine plays a key role in the biosynthesis of other amino acids and is important in the structure and function of many proteins and enzymes. Phenylalanine is converted to tyrosine, used in the biosynthesis of dopamine and norepinephrine neurotransmitters. The L-form of Phenylalanine is incorporated into proteins, while the D-form acts as a painkiller. Absorption of ultraviolet radiation by Phenylalanine is used to quantify protein amounts. (NCI04) Phenylalanine is an essential amino acid and the precursor for the amino acid tyrosine. Like tyrosine, it is the precursor of catecholamines in the body (tyramine, dopamine, epinephrine and norepinephrine).

Aspartame appears to be nutritious except in hot beverages; however, it should be avoided by phenylketonurics and pregnant women. Phenylketonurics, who have a genetic error of phenylalanine metabolism, have elevated serum plasma levels of phenylalanine up to 400 times normal. Mild phenylketonuria can be an unsuspected cause of hyperactivity, learning problems, and other developmental problems in children. Phenylalanine can be an effective pain reliever. Its use in premenstrual syndrome and Parkinsons may enhance the effects of acupuncture and electric transcutaneous nerve stimulation (TENS). Phenylalanine and tyrosine, like L-dopa, produce a catecholamine effect. Phenylalanine is better absorbed than tyrosine and may cause fewer headaches. Low phenylalanine diets have been prescribed for certain cancers with mixed results. Some tumors use more phenylalanine (particularly melatonin-producing tumors called melanoma). One strategy is to exclude this amino acid from the diet, i.e., a Phenylketonuria (PKU) diet (compliance is a difficult issue; it is hard to quantify and is under-researched). The other strategy is just to increase phenylalanines competing amino acids, i.e., tryptophan, valine, isoleucine and leucine, but not tyrosine.

View More ... L-phenylalanine, also known as phe or f, belongs to phenylalanine and derivatives class of compounds. Those are compounds containing phenylalanine or a derivative thereof resulting from reaction of phenylalanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. L-phenylalanine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). L-phenylalanine can be found in watermelon, which makes L-phenylalanine a potential biomarker for the consumption of this food product. L-phenylalanine can be found primarily in most biofluids, including sweat, blood, urine, and cerebrospinal fluid (CSF), as well as throughout all human tissues. L-phenylalanine exists in all living species, ranging from bacteria to humans. In humans, L-phenylalanine is involved in a couple of metabolic pathways, which include phenylalanine and tyrosine metabolism and transcription/Translation. L-phenylalanine is also involved in few metabolic disorders, which include phenylketonuria, tyrosinemia type 2 (or richner-hanhart syndrome), and tyrosinemia type 3 (TYRO3). Moreover, L-phenylalanine is found to be associated with viral infection, dengue fever, hypothyroidism, and myocardial infarction. L-phenylalanine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Phenylalanine (Phe or F) is an α-amino acid with the formula C 9H 11NO 2. It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. This essential amino acid is classified as neutral, and nonpolar because of the inert and hydrophobic nature of the benzyl side chain. The L-isomer is used to biochemically form proteins, coded for by DNA. The codons for L-phenylalanine are UUU and UUC. Phenylalanine is a precursor for tyrosine; the monoamine neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline); and the skin pigment melanin . Hepatic. L-phenylalanine that is not metabolized in the liver is distributed via the systemic circulation to the various tissues of the body, where it undergoes metabolic reactions similar to those that take place in the liver (DrugBank). If PKU is diagnosed early, an affected newborn can grow up with normal brain development, but only by managing and controlling phenylalanine levels through diet, or a combination of diet and medication. The diet requires severely restricting or eliminating foods high in phenylalanine, such as meat, chicken, fish, eggs, nuts, cheese, legumes, milk and other dairy products. Starchy foods, such as potatoes, bread, pasta, and corn, must be monitored. Optimal health ranges (or "target ranges") of serum phenylalanine are between 120 and 360 µmol/L, and aimed to be achieved during at least the first 10 years of life. Recently it has been found that a chiral isomer of L-phenylalanine (called D-phenylalanine) actually arrests the fibril formation by L-phenylalanine and gives rise to flakes. These flakes do not propagate further and prevent amyloid formation by L-phenylalanine. D-phenylalanine may qualify as a therapeutic molecule in phenylketonuria (A8161) (T3DB). L-Phenylalanine.

beta-Carotene
Beta-carotene is a cyclic carotene obtained by dimerisation of all-trans-retinol. A strongly-coloured red-orange pigment abundant in plants and fruit and the most active and important provitamin A carotenoid. It has a role as a biological pigment, a provitamin A, a plant metabolite, a human metabolite, a mouse metabolite, a cofactor, a ferroptosis inhibitor and an antioxidant. It is a cyclic carotene and a carotenoid beta-end derivative. Beta-carotene, with the molecular formula C40H56, belongs to the group of carotenoids consisting of isoprene units. The presence of long chains of conjugated double bonds donates beta-carotene with specific colors. It is the most abundant form of carotenoid and it is a precursor of the vitamin A. Beta-carotene is composed of two retinyl groups. It is an antioxidant that can be found in yellow, orange and green leafy vegetables and fruits. Under the FDA, beta-carotene is considered as a generally recognized as safe substance (GRAS). Beta-Carotene is a natural product found in Epicoccum nigrum, Lonicera japonica, and other organisms with data available. Beta-Carotene is a naturally-occurring retinol (vitamin A) precursor obtained from certain fruits and vegetables with potential antineoplastic and chemopreventive activities. As an anti-oxidant, beta carotene inhibits free-radical damage to DNA. This agent also induces cell differentiation and apoptosis of some tumor cell types, particularly in early stages of tumorigenesis, and enhances immune system activity by stimulating the release of natural killer cells, lymphocytes, and monocytes. (NCI04) beta-Carotene is a metabolite found in or produced by Saccharomyces cerevisiae. A carotenoid that is a precursor of VITAMIN A. Beta carotene is administered to reduce the severity of photosensitivity reactions in patients with erythropoietic protoporphyria (PORPHYRIA, ERYTHROPOIETIC). See also: Lycopene (part of); Broccoli (part of); Lycium barbarum fruit (part of). Beta-Carotene belongs to the class of organic compounds known as carotenes. These are a type of polyunsaturated hydrocarbon molecules containing eight consecutive isoprene units. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Beta-carotene is therefore considered to be an isoprenoid lipid molecule. Beta-carotene is a strongly coloured red-orange pigment abundant in fungi, plants, and fruits. It is synthesized biochemically from eight isoprene units and therefore has 40 carbons. Among the carotenes, beta-carotene is distinguished by having beta-rings at both ends of the molecule. Beta-Carotene is biosynthesized from geranylgeranyl pyrophosphate. It is the most common form of carotene in plants. In nature, Beta-carotene is a precursor (inactive form) to vitamin A. Vitamin A is produed via the action of beta-carotene 15,15-monooxygenase on carotenes. In mammals, carotenoid absorption is restricted to the duodenum of the small intestine and dependent on a class B scavenger receptor (SR-B1) membrane protein, which is also responsible for the absorption of vitamin E. One molecule of beta-carotene can be cleaved by the intestinal enzyme Beta-Beta-carotene 15,15-monooxygenase into two molecules of vitamin A. Beta-Carotene contributes to the orange color of many different fruits and vegetables. Vietnamese gac and crude palm oil are particularly rich sources, as are yellow and orange fruits, such as cantaloupe, mangoes, pumpkin, and papayas, and orange root vegetables such as carrots and sweet potatoes. Excess beta-carotene is predominantly stored in the fat tissues of the body. The most common side effect of excessive beta-carotene consumption is carotenodermia, a physically harmless condition that presents as a conspicuous orange skin tint arising from deposition of the carotenoid in the outermost layer of the epidermis. Yellow food colour, dietary supplement, nutrient, Vitamin A precursor. Nutriceutical with antioxidation props. beta-Carotene is found in many foods, some of which are summer savory, gram bean, sunburst squash (pattypan squash), and other bread product.

Lutein
Lutein is a common carotenoid xanthophyll found in nature. Carotenoids are among the most common pigments in nature and are natural lipid-soluble antioxidants. Lutein is one of the two carotenoids (the other is zeaxanthin) that accumulate in the eye lens and macular region of the retina with concentrations in the macula greater than those found in plasma and other tissues. Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The main difference between them is in the location of a double bond in one of the end rings. This difference gives lutein three chiral centers whereas zeaxanthin has two. A relationship between macular pigment optical density, a marker of lutein and zeaxanthin concentration in the macula, and lens optical density, an antecedent of cataractous changes, has been suggested. The xanthophylls may act to protect the eye from ultraviolet phototoxicity via quenching reactive oxygen species and/or other mechanisms. Some observational studies have shown that generous intakes of lutein and zeaxanthin, particularly from certain xanthophyll-rich foods like spinach, broccoli, and eggs, are associated with a significant reduction in the risk for cataracts (up to 20\\\\\%) and age-related macular degeneration (up to 40\\\\\%). While the pathophysiology of cataract and age-related macular degeneration is complex and contains both environmental and genetic components, research studies suggest dietary factors including antioxidant vitamins and xanthophylls may contribute to a reduction in the risk of these degenerative eye diseases. Further research is necessary to confirm these observations (PMID: 11023002). Lutein is a carotenol. It has a role as a food colouring and a plant metabolite. It derives from a hydride of a (6R)-beta,epsilon-carotene. Lutein is an xanthophyll and one of 600 known naturally occurring carotenoids. Lutein is synthesized only by plants and like other xanthophylls is found in high quantities in green leafy vegetables such as spinach, kale and yellow carrots. In green plants, xanthophylls act to modulate light energy and serve as non-photochemical quenching agents to deal with triplet chlorophyll (an excited form of chlorophyll), which is overproduced at very high light levels, during photosynthesis. Lutein is a natural product found in Eupatorium cannabinum, Hibiscus syriacus, and other organisms with data available. Lutein is lutein (LOO-teen) is a oxygenated carotenoid found in vegetables and fruits. lutein is found in the macula of the eye, where it is believed to act as a yellow filter. Lutein acts as an antioxidant, protecting cells against the damaging effects of free radicals. A xanthophyll found in the major LIGHT-HARVESTING PROTEIN COMPLEXES of plants.

Phytic acid
myo-Inositol hexakisphosphate is an intermediate in inositol phosphate metabolism. It can be generated from D-myo-inositol 1,3,4,5,6-pentakisphosphate via the enzyme inositol-pentakisphosphate 2-kinase (EC 2.7.1.158). myo-Inositol hexakisphosphate is also known as phytic acid. It can be used clinically as a complexing agent for the removal of traces of heavy metal ions. It acts also as a hypocalcemic agent. Phytic acid is a strong chelator of important minerals such as calcium, magnesium, iron, and zinc and can, therefore, contribute to mineral deficiencies in developing countries. For people with a particularly low intake of essential minerals, especially young children and those in developing countries, this effect can be undesirable. However, dietary mineral chelators help prevent over-mineralization of joints, blood vessels, and other parts of the body, which is most common in older persons. Phytic acid is a plant antioxidant (PMID: 3040709). Myo-inositol hexakisphosphate is a myo-inositol hexakisphosphate in which each hydroxy group of myo-inositol is monophosphorylated. It has a role as an iron chelator, an antineoplastic agent, a signalling molecule, an Escherichia coli metabolite, a mouse metabolite and a cofactor. It is a conjugate acid of a myo-inositol hexakisphosphate(12-). Phytic acid is under investigation in clinical trial NCT01000233 (Value of Oral Phytate (InsP6) in the Prevention of Progression of the Cardiovascular Calcifications). Myo-inositol hexakisphosphate is a metabolite found in or produced by Escherichia coli (strain K12, MG1655).

alpha-Carotene
alpha-Carotene belongs to the class of organic compounds known as carotenes. These are a type of unsaturated hydrocarbons containing eight consecutive isoprene units. They are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. alpha-Carotene is considered to be an isoprenoid lipid molecule. alpha-Carotene is one of the primary isomers of carotene. Plasma levels of alpha-carotene are positively associated with the detection rate of AFB1-DNA adducts in a dose-dependent manner, whereas plasma lycopene level was inversely related to the presence of the adducts in urine (PMID: 9214602). (6R)-beta,epsilon-carotene is an alpha-carotene. It is an enantiomer of a (6S)-beta,epsilon-carotene. alpha-Carotene is a natural product found in Hibiscus syriacus, Scandix stellata, and other organisms with data available.

Zeaxanthin
Zeaxanthin is a carotenoid xanthophyll and is one of the most common carotenoid found in nature. It is the pigment that gives corn, saffron, and many other plants their characteristic color. Zeaxanthin breaks down to form picrocrocin and safranal, which are responsible for the taste and aroma of saffron Carotenoids are among the most common pigments in nature and are natural lipid soluble antioxidants. Zeaxanthin is one of the two carotenoids (the other is lutein) that accumulate in the eye lens and macular region of the retina with concentrations in the macula greater than those found in plasma and other tissues. Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The main difference between them is in the location of a double bond in one of the end rings. This difference gives lutein three chiral centers whereas zeaxanthin has two. A relationship between macular pigment optical density, a marker of lutein and zeaxanthin concentration in the macula, and lens optical density, an antecedent of cataractous changes, has been suggested. The xanthophylls may act to protect the eye from ultraviolet phototoxicity via quenching reactive oxygen species and/or other mechanisms. Some observational studies have shown that generous intakes of lutein and zeaxanthin, particularly from certain xanthophyll-rich foods like spinach, broccoli and eggs, are associated with a significant reduction in the risk for cataract (up to 20\\%) and for age-related macular degeneration (up to 40\\%).

Melezitose
Melezitose, also spelled melicitose, is a nonreducing trisaccharide sugar that is produced by many plant sap eating insects, including aphids such as Cinara pilicornis by an enzyme reaction. This is beneficial to the insects, as it reduces the stress of osmosis by reducing their own water potential. The melezitose is part of the honeydew which acts as an attractant for ants and also as a food for bees. This is useful to the lice as they have a symbiotic relationship with ants. Melezitose can be partially hydrolyzed to glucose and turanose the latter of which is an isomer of sucrose (Wikipedia). Melezitose is a trisaccharide produced by insects such as aphids.

3-Hydroxyisovaleric acid
3-Hydroxyisovaleric acid is a normal human metabolite excreted in the urine. It is a byproduct of the leucine degradation pathway. Production of 3-hydroxyisovaleric acid begins with the conversion of 3-methylcrotonyl-CoA into 3-methylglutaconyl-CoA in the mitochondria by the biotin-dependent enzyme methylcrotonyl-CoA carboxylase. Biotin deficiencies, certain lifestyle habits (smoking), or specific genetic conditions can reduce methylcrotonyl-CoA carboxylase activity. This reduction can lead to a buildup of 3-methylcrotonyl-CoA, which is converted into 3-hydroxyisovaleryl-CoA by the enzyme enoyl-CoA hydratase. Increased concentrations of 3-methylcrotonyl-CoA and 3-hydroxyisovaleryl-CoA can lead to a disruption of the esterified CoA:free CoA ratio, and ultimately to mitochondrial toxicity. Detoxification of these metabolic end products occur via the transfer of the 3-hydroxyisovaleryl moiety to carnitine forming 3-hydroxyisovaleric acid-carnitine or 3HIA-carnitine, which is then transferred across the inner mitochondrial membrane where 3-hydroxyisovaleric acid is released as the free acid (PMID: 21918059). 3-Hydroxyisovaleric acid has been found to be elevated in smokers and in subjects undergoing long-term anticonvulsant therapy with carbamazepine and/or phenytoin. These levels are elevated due to impairment of renal reclamation of biotin. Levels may also be increased from prolonged consumption of raw egg-whites (PMID: 16895887, 9523856, 15447901, 9176832) (OMIM: 210210, 253270, 600529, 253260, 246450, 210200, 238331). When present in sufficiently high levels, 3-hydroxyisovaleric 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 3-hydroxyisovaleric acid are associated with at least a dozen inborn errors of metabolism, including 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, 3-methylglutaconic aciduria type I, biotinidase deficiency and isovaleric aciduria, dihydrolipoamide dehydrogenase deficiency, 3-methylcrotonyl-CoA carboxylase 1 deficiency, 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, late-onset multiple carboxylase deficiency, holocarboxylase synthetase deficiency, and 3-methylcrotonyl-CoA carboxylase 2 deficiency. 3-Hydroxyisovaleric 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, liver, and kidney abnormalities, 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. 3-Hydroxyisovaleric acid is a normal human metabolite excreted in the urine. Elevated levels of this compound are found in several inherited disorders such as Dihydrolipoamide dehydrogenase Deficiency, 3-Methylcrotonyl-CoA carboxylase 1 deficiency, 3-Hydroxy-3-methylglutaryl-CoA lyase deficiency (3-hydroxy-3-methylglutaryl -CoA lyase Deficiency, Biotinidase deficiency multiple carboxylase deficiency late-onset , Late onset multiple carboxylase deficiency, HolMcarboxylase synthetase deficiency, 3-Methylcrotonyl-CoA carboxylase 2 deficiency. 3-Hydroxyisovaleric acid is also elevated in smokers, in subjects undergoing long-term anticonvulsant therapy with carbamazepine and/or phenytoin. These levels are elevated due to impairment of renal reclamation of biotin. Levels may also be increased from prolonged consumption of raw egg-whites (PMID: 16895887, 9523856, 15447901, 9176832)(OMIM: 210210, 253270, 600529, 253260, 246450, 210200, 238331) [HMDB] 3-Hydroxyisovaleric acid is a normal endogenous metabolite excreted in the urine.

3-Hydroxybenzoic acid
3-Hydroxybenzoic acid, also known as 3-hydroxybenzoate or 3-carboxyphenol, belongs to the class of organic compounds known as hydroxybenzoic acid derivatives. Hydroxybenzoic acid derivatives are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. 3-Hydroxybenzoic acid exists in all living organisms, ranging from bacteria to humans. Outside of the human body, 3-hydroxybenzoic acid is found, on average, in the highest concentration in american cranberries and beers. 3-hydroxybenzoic acid has also been detected, but not quantified in a few different foods, such as bilberries, citrus, and corns. As well, 3-Hydroxybenzoic Acid can be found in the pineapple fruit. It can also be formed by a Pseudomonas species from 3-Chlorobenzoic acid. 3-Hydroxybenzoic acid is a monohydroxybenzoic acid. 3-Hydroxybenzoic acid can be obtained by the alkali fusion of 3-sulfobenzoic acid between 210-220 °C. 3-Hydroxybenzoic acid is a component of castoreum, the exudate from the castor sacs of the mature North American beaver (Castor canadensis) and the European beaver (Castor fiber), used in perfumery.

Aminoadipic acid
Aminoadipic acid (CAS: 542-32-5), also known as 2-aminoadipate, is a metabolite in the principal biochemical pathway of lysine. It is an intermediate in the metabolism (i.e. breakdown or degradation) of lysine and saccharopine. It antagonizes neuroexcitatory activity modulated by the glutamate receptor N-methyl-D-aspartate (NMDA). Aminoadipic acid has also been shown to inhibit the production of kynurenic acid, a broad spectrum excitatory amino acid receptor antagonist, in brain tissue slices (PMID: 8566117). Recent studies have shown that aminoadipic acid is elevated in prostate biopsy tissues from prostate cancer patients (PMID: 23737455). Mutations in DHTKD1 (dehydrogenase E1 and transketolase domain-containing protein 1) have been shown to cause human 2-aminoadipic aciduria and 2-oxoadipic aciduria via impaired decarboxylation of 2-oxoadipate to glutaryl-CoA, which is the last step in the lysine degradation pathway (PMID: 23141293). Aging, diabetes, sepsis, and renal failure are known to catalyze the oxidation of lysyl residues to form 2-aminoadipic acid in human skin collagen and potentially other tissues (PMID: 18448817). Proteolytic breakdown of these tissues can lead to the release of free 2-aminoadipic acid. Studies in rats indicate that aminoadipic acid (along with the three branched-chain amino acids: leucine, valine, and isoleucine) levels are elevated in the pre-diabetic phase and so aminoadipic acid may serve as a predictive biomarker for the development of diabetes (PMID: 15389298). Long-term hyperglycemia of endothelial cells can also lead to elevated levels of aminoadipate which is thought to be a sign of lysine breakdown through oxidative stress and reactive oxygen species (ROS) (PMID: 21961526). 2-Aminoadipate is a potential small-molecule marker of oxidative stress (PMID: 21647514). Therefore, depending on the circumstances aminoadipic acid can act as an acidogen, a diabetogen, an atherogen, and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A diabetogen is a compound that can lead to type 2 diabetes. An atherogen is a compound that leads to atherosclerosis and cardiovascular disease. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of aminoadipic acid are associated with at least two inborn errors of metabolism including 2-aminoadipic aciduria and 2-oxoadipic aciduria. Aminoadipic acid is an organic acid and 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. As a diabetogen, serum aminoadipic levels appear to regulate glucose homeostasis and have been highly predictive of individuals who later develop diabetes (PMID: 24091325). In particular, aminoadipic acid lowers fasting plasma glucose levels and enhances insulin secretion from human islets. As an atherogen, aminoadipic acid has been found to be produced at high levels via protein lysine oxidation in atherosclerotic plaques (PMID: 28069522).

L-Aspartic acid
Aspartic acid (Asp), also known as L-aspartic acid or as aspartate, the name of its anion, 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-aspartic acid is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Aspartic acid is found in all organisms ranging from bacteria to plants to animals. It is classified as an acidic, charged (at physiological pH), aliphatic amino acid. In humans, aspartic acid is a nonessential amino acid derived from glutamic acid by enzymes using vitamin B6. However, in the human body, aspartate is most frequently synthesized through the transamination of oxaloacetate. A non-essential amino acid is an amino acid that can be synthesized from central metabolic pathway intermediates in humans and is not required in the diet. As its name indicates, aspartic acid is the carboxylic acid analog of asparagine. The D-isomer of aspartic acid (D-aspartic acid) is one of two D-amino acids commonly found in mammals. Aspartic acid was first discovered in 1827 by Auguste-Arthur Plisson and Étienne Ossian Henry by hydrolysis of asparagine, which had been isolated from asparagus juice in 1806. Aspartate has many biochemical roles. It is a neurotransmitter, a metabolite in the urea cycle and it participates in gluconeogenesis. It carries reducing equivalents in the malate-aspartate shuttle, which utilizes the ready interconversion of aspartate and oxaloacetate, which is the oxidized (dehydrogenated) derivative of malic acid. Aspartate donates one nitrogen atom in the biosynthesis of inosine, the precursor to the purine bases which are key to DNA biosynthesis. In addition, aspartic acid acts as a hydrogen acceptor in a chain of ATP synthase. Aspartic acid is a major excitatory neurotransmitter, which is sometimes found to be increased in epileptic and stroke patients. It is decreased in depressed patients and in patients with brain atrophy. As a neurotransmitter, aspartic acid may provide resistance to fatigue and thus lead to endurance, although the evidence to support this idea is not strong (Wikipedia). Aspartic acid supplements are being evaluated. Five grams can raise blood levels. Magnesium and zinc may be natural inhibitors of some of the actions of aspartic acid. Aspartic acid, when chemically coupled with the amino acid D-phenylalanine, is a part of a natural sweetener, aspartame. This sweetener is an advance in artificial sweeteners, and is probably safe in normal doses to all except phenylketonurics. Aspartic acid may be a significant immunostimulant of the thymus and can protect against some of the damaging effects of radiation. Aspartic acid is found in higher abundance in: oysters, luncheon meats, sausage meat, wild game, sprouting seeds, oat flakes, avocado, asparagus, young sugarcane, and molasses from sugar beets.

N-Methyl-D-aspartic acid
N-Methyl-D-aspartic acid is an amino acid derivative acting as a specific agonist at the NMDA receptor, and therefore mimics the action of the neurotransmitter glutamate on that receptor. In contrast to glutamate, NMDA binds to and regulates the above receptor only, but not other glutamate receptors. NMDA is a water-soluble endogenous metabolite that plays an important role in the neuroendocrine system of species across Animalia (PMID:18096065). It was first synthesized in the 1960s (PMID:14056452). NMDA is an excitotoxin; this trait has applications in behavioural neuroscience research. The body of work utilizing this technique falls under the term "lesion studies." Researchers apply NMDA to specific regions of an (animal) subjects brain or spinal cord and subsequently test for the behaviour of interest, such as operant behaviour. If the behaviour is compromised, it suggests that the destroyed tissue was part of a brain region that made an important contribution to the normal expression of that behaviour. Examples of antagonists of the NMDA receptor are ketamine, amantadine, dextromethorphan (DXM), riluzole, and memantine. They are commonly referred to as NMDA receptor antagonists (PMID:28877137). N-Methyl-D-aspartic acid is an amino acid derivative acting as a specific agonist at the NMDA receptor, and therefore mimics the action of the neurotransmitter glutamate on that receptor. In contrast to glutamate, NMDA binds to and regulates the above receptor only, but not other glutamate receptors.

Baclofen
Baclofen is a gamma-amino-butyric acid (GABA) derivative used as a skeletal muscle relaxant. Baclofen stimulates GABA-B receptors leading to decreased frequency and amplitude of muscle spasms. It is especially useful in treating muscle spasticity associated with spinal cord injury. It appears to act primarily at the spinal cord level by inhibiting spinal polysynaptic afferent pathways and, to a lesser extent, monosynaptic afferent pathways.

Baclofen mimics the action of GABA and produces slow presynaptic inhibition through the GABAB receptor. Baclofen has high blood brain barrier penetrance. Baclofen has the potential for muscle spasticity research[1][2][3].

Stearic acid
Stearic acid, also known as stearate or N-octadecanoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, stearic acid is considered to be a fatty acid lipid molecule. Stearic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Stearic acid can be synthesized from octadecane. Stearic acid is also a parent compound for other transformation products, including but not limited to, 3-oxooctadecanoic acid, (9S,10S)-10-hydroxy-9-(phosphonooxy)octadecanoic acid, and 16-methyloctadecanoic acid. Stearic acid can be found in a number of food items such as green bell pepper, common oregano, ucuhuba, and babassu palm, which makes stearic acid a potential biomarker for the consumption of these food products. Stearic acid can be found primarily in most biofluids, including urine, feces, cerebrospinal fluid (CSF), and sweat, as well as throughout most human tissues. Stearic acid exists in all living species, ranging from bacteria to humans. In humans, stearic acid is involved in the plasmalogen synthesis. Stearic acid is also involved in mitochondrial beta-oxidation of long chain saturated fatty acids, which is a metabolic disorder. Moreover, stearic acid is found to be associated with schizophrenia. Stearic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Stearic acid ( STEER-ik, stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain and has the IUPAC name octadecanoic acid. It is a waxy solid and its chemical formula is C17H35CO2H. Its name comes from the Greek word στέαρ "stéar", which means tallow. The salts and esters of stearic acid are called stearates. As its ester, stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid. The triglyceride derived from three molecules of stearic acid is called stearin . Stearic acid, also known as octadecanoic acid or C18:0, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Stearic acid (its ester is called stearate) is a saturated fatty acid that has 18 carbons and is therefore a very hydrophobic molecule that is practically insoluble in water. It exists as a waxy solid. In terms of its biosynthesis, stearic acid is produced from carbohydrates via the fatty acid synthesis machinery wherein acetyl-CoA contributes two-carbon building blocks, up to the 16-carbon palmitate, via the enzyme complex fatty acid synthase (FA synthase), at which point a fatty acid elongase is needed to further lengthen it. After synthesis, there are a variety of reactions it may undergo, including desaturation to oleate via stearoyl-CoA desaturase (PMID: 16477801). Stearic acid is found in all living organisms ranging from bacteria to plants to animals. It is one of the useful types of saturated fatty acids that comes from many animal and vegetable fats and oils. For example, it is a component of cocoa butter and shea butter. It is used as a food additive, in cleaning and personal care products, and in lubricants. Its name comes from the Greek word stear, which means ‚Äòtallow‚Äô or ‚Äòhard fat‚Äô. Stearic acid is a long chain dietary saturated fatty acid which exists in many animal and vegetable fats and oils. Stearic acid is a long chain dietary saturated fatty acid which exists in many animal and vegetable fats and oils.
Roxithromycin
Roxithromycin is a semi-synthetic macrolide antibiotic. It is very similar in composition, chemical structure and mechanism of action to erythromycin, azithromycin, or clarithromycin. Roxithromycin prevents bacteria from growing, by interfering with their protein synthesis. Roxithromycin binds to the subunit 50S of the bacterial ribosome, and thus inhibits the translocation of peptides. Roxithromycin has similar antimicrobial spectrum as erythromycin, but is more effective against certain gram-negative bacteria, particularly Legionella pneumophila. It can treat respiratory tract, urinary and soft tissue infections.

Guanosine diphosphate
Guanosine diphosphate, also known as gdp or 5-diphosphate, guanosine, is a member of the class of compounds known as purine ribonucleoside diphosphates. Purine ribonucleoside diphosphates are purine ribobucleotides with diphosphate group linked to the ribose moiety. Guanosine diphosphate is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Guanosine diphosphate can be found in a number of food items such as strawberry, onion-family vegetables, walnut, and scarlet bean, which makes guanosine diphosphate a potential biomarker for the consumption of these food products. Guanosine diphosphate can be found primarily in blood and cerebrospinal fluid (CSF). Guanosine diphosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine diphosphate is involved in several metabolic pathways, some of which include betahistine h1-antihistamine action, fexofenadine h1-antihistamine action, clocinizine h1-antihistamine action, and bepotastine h1-antihistamine action. Guanosine diphosphate is also involved in several metabolic disorders, some of which include adenine phosphoribosyltransferase deficiency (APRT), canavan disease, gout or kelley-seegmiller syndrome, and pyruvate dehydrogenase complex deficiency. Moreover, guanosine diphosphate is found to be associated with epilepsy, subarachnoid hemorrhage, neuroinfection, and stroke. Guanosine diphosphate, abbreviated GDP, is a nucleoside diphosphate. It is an ester of pyrophosphoric acid with the nucleoside guanosine. GDP consists of the pyrophosphate group, the pentose sugar ribose, and the nucleobase guanine . Guanosine diphosphate, also known as 5-GDP or 5-diphosphate, guanosine, belongs to the class of organic compounds known as purine ribonucleoside diphosphates. These are purine ribobucleotides with diphosphate group linked to the ribose moiety. Guanosine diphosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine diphosphate is involved in intracellular signalling through adenosine receptor A2B and adenosine. Outside of the human body, Guanosine diphosphate has been detected, but not quantified in several different foods, such as devilfish, java plums, green beans, almonds, and orange mints. Guanosine diphosphate is a purine ribonucleoside 5-diphosphate resulting from the formal condensation of the hydroxy group at the 5 position of guanosine with pyrophosphoric acid.

Guanosine triphosphate
Guanosine-5-triphosphate (GTP) is a purine nucleoside triphosphate. It is one of the building blocks needed for the synthesis of RNA during the transcription process. Its structure is similar to that of the guanosine nucleoside, the only difference being that nucleotides like GTP have phosphates on their ribose sugar. GTP has the guanine nucleobase attached to the 1 carbon of the ribose and it has the triphosphate moiety attached to riboses 5 carbon. GTP is essential to signal transduction, in particular with G-proteins, in second-messenger mechanisms where it is converted to guanosine diphosphate (GDP) through the action of GTPases. Guanosine triphosphate, also known as 5-GTP or H4GTP, belongs to the class of organic compounds known as purine ribonucleoside triphosphates. These are purine ribonucleotides with a triphosphate group linked to the ribose moiety. Thus, a GTP-bound tubulin serves as a cap at the tip of microtubule to protect from depolymerization; and, once the GTP is hydrolyzed, the microtubule begins to depolymerize and shrink rapidly. Guanosine triphosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine triphosphate is involved in intracellular signalling through adenosine receptor A2B and adenosine. Guanosine-5-triphosphate (GTP) is a purine nucleoside triphosphate. Outside of the human body, guanosine triphosphate has been detected, but not quantified in several different foods, such as mandarin orange (clementine, tangerine), coconuts, new zealand spinachs, sweet marjorams, and pepper (capsicum). Cyclic guanosine triphosphate (cGTP) helps cyclic adenosine monophosphate (cAMP) activate cyclic nucleotide-gated ion channels in the olfactory system. It also has the role of a source of energy or an activator of substrates in metabolic reactions, like that of ATP, but more specific. It is used as a source of energy for protein synthesis and gluconeogenesis. For instance, a GTP molecule is generated by one of the enzymes in the citric acid cycle. GTP is also used as an energy source for the translocation of the ribosome towards the 3 end of the mRNA. During microtubule polymerization, each heterodimer formed by an alpha and a beta tubulin molecule carries two GTP molecules, and the GTP is hydrolyzed to GDP when the tubulin dimers are added to the plus end of the growing microtubule. The importing of these proteins plays an important role in several pathways regulated within the mitochondria organelle, such as converting oxaloacetate to phosphoenolpyruvate (PEP) in gluconeogenesis. GTP is involved in energy transfer within the cell. Guanosine triphosphate (GTP) is a guanine nucleotide containing three phosphate groups esterified to the sugar moiety. GTP functions as a carrier of phosphates and pyrophosphates involved in channeling chemical energy into specific biosynthetic pathways. GTP activates the signal transducing G proteins which are involved in various cellular processes including proliferation, differentiation, and activation of several intracellular kinase cascades. Proliferation and apoptosis are regulated in part by the hydrolysis of GTP by small GTPases Ras and Rho. Another type of small GTPase, Rab, plays a role in the docking and fusion of vesicles and may also be involved in vesicle formation. In addition to its role in signal transduction, GTP also serves as an energy-rich precursor of mononucleotide units in the enzymatic biosynthesis of DNA and RNA. [HMDB]. Guanosine triphosphate is found in many foods, some of which are oat, star fruit, lingonberry, and linden.

Phosphoenolpyruvic acid
Phosphoenolpyruvate, also known as pep or 2-(phosphonooxy)-2-propenoic acid, is a member of the class of compounds known as phosphate esters. Phosphate esters are organic compounds containing phosphoric acid ester functional group, with the general structure R1P(=O)(R2)OR3. R1,R2 = O,N, or halogen atom; R3 = organyl group. Phosphoenolpyruvate is soluble (in water) and an extremely strong acidic compound (based on its pKa). Phosphoenolpyruvate can be found in a number of food items such as okra, endive, chestnut, and dandelion, which makes phosphoenolpyruvate a potential biomarker for the consumption of these food products. Phosphoenolpyruvate can be found primarily in blood, cellular cytoplasm, and saliva, as well as in human prostate tissue. Phosphoenolpyruvate exists in all living species, ranging from bacteria to humans. In humans, phosphoenolpyruvate is involved in several metabolic pathways, some of which include glycolysis, amino sugar metabolism, gluconeogenesis, and glycogenosis, type IC. Phosphoenolpyruvate is also involved in several metabolic disorders, some of which include glycogen storage disease type 1A (GSD1A) or von gierke disease, salla disease/infantile sialic acid storage disease, phosphoenolpyruvate carboxykinase deficiency 1 (PEPCK1), and pyruvate dehydrogenase complex deficiency. Phosphoenolpyruvate (2-phosphoenolpyruvate, PEP) as the ester derived from the enol of pyruvate and phosphate. It exists as an anion; the parent acid, which is only of theoretical interest, is phosphoenolpyruvic acid. PEP is an important intermediate in biochemistry. It has the highest-energy phosphate bond found (−61.9 kJ/mol) in living organisms, and is involved in glycolysis and gluconeogenesis. In plants, it is also involved in the biosynthesis of various aromatic compounds, and in carbon fixation; in bacteria, it is also used as the source of energy for the phosphotransferase system . Phosphoenolpyruvate (PEP) is an important chemical compound in biochemistry. It has a high energy phosphate bond, and is involved in glycolysis and gluconeogenesis. In glycolysis, PEP is formed by the action of the enzyme enolase on 2-phosphoglycerate. Metabolism of PEP to pyruvate by pyruvate kinase (PK) generates 1 molecule of adenosine triphosphate (ATP) via substrate-level phosphorylation. ATP is one of the major currencies of chemical energy within cells. In gluconeogenesis, PEP is formed from the decarboxylation of oxaloacetate and hydrolysis of 1 guanosine triphosphate molecule. This reaction is catalyzed by the enzyme phosphoenolpyruvate carboxykinase (PEPCK). This reaction is a rate-limiting step in gluconeogenesis. (wikipedia).

L-Cysteine
Cysteine (Cys), also known as L-cysteine 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-alanine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Cysteine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar, sulfur-containing amino acid. Cysteine is an important source of sulfur in human metabolism, and although it is classified as a non-essential amino acid, cysteine may be essential for infants, the elderly, and individuals with certain metabolic disease or who suffer from malabsorption syndromes. Cysteine can occasionally be considered as an essential or conditionally essential amino acid. Cysteine is unique amongst the twenty natural amino acids as it contains a thiol group. Thiol groups can undergo oxidation/reduction (redox) reactions; when cysteine is oxidized it can form cystine, which is two cysteine residues joined by a disulfide bond. This reaction is reversible since the reduction of this disulphide bond regenerates two cysteine molecules. The disulphide bonds of cystine are crucial to defining the structures of many proteins. Cysteine is often involved in electron-transfer reactions, and help the enzyme catalyze its reaction. Cysteine is also part of the antioxidant glutathione. N-Acetyl-L-cysteine (NAC) is a form of cysteine where an acetyl group is attached to cysteines nitrogen atom and is sold as a dietary supplement. Cysteine is named after cystine, which comes from the Greek word kustis meaning bladder (cystine was first isolated from kidney stones). Oxidation of cysteine can produce a disulfide bond with another thiol and further oxidation can produce sulphfinic or sulfonic acids. The cysteine thiol group is also a nucleophile and can undergo addition and substitution reactions. Thiol groups become much more reactive when they are ionized, and cysteine residues in proteins have pKa values close to neutrality, so they are often in their reactive thiolate form in the cell. The thiol group also has a high affinity for heavy metals and proteins containing cysteine will bind metals such as mercury, lead, and cadmium tightly. Due to this ability to undergo redox reactions, cysteine has antioxidant properties. Cysteine is important in energy metabolism. As cystine, it is a structural component of many tissues and hormones. Cysteine has clinical uses ranging from treating baldness to psoriasis to preventing smokers hack. In some cases, oral cysteine therapy has proved excellent for treatment of asthmatics, enabling them to stop theophylline and other medications. Cysteine also enhances the effect of topically applied silver, tin, and zinc salts in preventing dental cavities. In the future, cysteine may play a role in the treatment of cobalt toxicity, diabetes, psychosis, cancer, and seizures (http://www.dcnutrition.com/AminoAcids/). Cysteine has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821).

Valinomycin (NSC 122023) inhibits lymphocyte proliferation by its effects on the cell membrane, and induces apoptosis in CHO cells[1]. Valinomycin induces activation of PINK1 leading to Parkin Ser65 phosphorylation[2].
Adenosine phosphosulfate
Adenosine phosphosulfate, also known as adenylylsulfate or adenosine sulfatophosphate, belongs to the class of organic compounds known as purine ribonucleoside monophosphates. These are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. Adenosine phosphosulfate exists in all living species, ranging from bacteria to humans. Within humans, adenosine phosphosulfate participates in a number of enzymatic reactions. In particular, adenosine phosphosulfate can be biosynthesized from sulfate through the action of the enzyme bifunctional 3-phosphoadenosine 5-phosphosulfate synthase 2. In addition, adenosine phosphosulfate can be converted into phosphoadenosine phosphosulfate; which is catalyzed by the enzyme bifunctional 3-phosphoadenosine 5-phosphosulfate synthase 2. In humans, adenosine phosphosulfate is involved in sulfate/sulfite metabolism. Outside of the human body, Adenosine phosphosulfate has been detected, but not quantified in several different foods, such as chia, yardlong beans, swiss chards, sapodilla, and chicory leaves. This could make adenosine phosphosulfate a potential biomarker for the consumption of these foods. An adenosine 5-phosphate having a sulfo group attached to one the phosphate OH groups. Adenosine phosphosulfate (also known as APS) is the initial compound formed by the action of ATP sulfurylase (or PAPS synthetase) on sulfate ions after sulfate uptake. PAPS synthetase 1 is a bifunctional enzyme with both ATP sulfurylase and APS kinase activity, which mediates two steps in the sulfate activation pathway. The first step is the transfer of a sulfate group to ATP to yield adenosine 5-phosphosulfate (APS), and the second step is the transfer of a phosphate group from ATP to APS yielding 3-phosphoadenylylsulfate (PAPS).

Kanamycin
Kanamycin is only found in individuals that have used or taken this drug. It is an antibiotic complex produced by Streptomyces kanamyceticus from Japanese soil. Comprises 3 components: kanamycin A, the major component, and kanamycins B and C, the minor components. [PubChem]Aminoglycosides like kanamycin "irreversibly" bind to specific 30S-subunit proteins and 16S rRNA. Specifically Kanamycin binds to four nucleotides of 16S rRNA and a single amino acid of protein S12. This interferes with decoding site in the vicinity of nucleotide 1400 in 16S rRNA of 30S subunit. This region interacts with the wobble base in the anticodon of tRNA. This leads to interference with the initiation complex, misreading of mRNA so incorrect amino acids are inserted into the polypeptide leading to nonfunctional or toxic peptides and the breakup of polysomes into nonfunctional monosomes.

Meclofenamic acid
Meclofenamic acid is only found in individuals that have used or taken this drug. It is a non-steroidal anti-inflammatory agent with antipyretic and antigranulation activities. It also inhibits prostaglandin biosynthesis. [PubChem]The mode of action, like that of other nonsteroidal anti-inflammatory agents, is not known. Therapeutic action does not result from pituitary-adrenal stimulation. In animal studies, meclofenamic acid was found to inhibit prostaglandin synthesis and to compete for binding at the prostaglandin receptor site. In vitro meclofenamic acid was found to be an inhibitor of human leukocyte 5-lipoxygenase activity. These properties may be responsible for the anti-inflammatory action of meclofenamic acid. There is no evidence that meclofenamic acid alters the course of the underlying disease.

Ropivacaine
Ropivacaine is only found in individuals that have used or taken this drug. It is a local anaesthetic drug belonging to the amino amide group. The name ropivacaine refers to both the racemate and the marketed S-enantiomer. Ropivacaine hydrochloride is commonly marketed by AstraZeneca under the trade name Naropin. [Wikipedia]Local anesthetics such as Ropivacaine block the generation and the conduction of nerve impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse, and by reducing the rate of rise of the action potential. Specifically, they block the sodium-channel and decrease chances of depolarization and consequent action potentials. In general, the progression of anesthesia is related to the diameter, myelination and conduction velocity of affected nerve fibers.

Paroxetine
Paroxetine hydrochloride and paroxetine mesylate belong to a class of antidepressant agents known as selective serotonin-reuptake inhibitors (SSRIs). Despite distinct structural differences between compounds in this class, SSRIs possess similar pharmacological activity. As with other antidepressant agents, several weeks of therapy may be required before a clinical effect is seen. SSRIs are potent inhibitors of neuronal serotonin reuptake. They have little to no effect on norepinephrine or dopamine reuptake and do not antagonize α- or β-adrenergic, dopamine D2 or histamine H1 receptors. During acute use, SSRIs block serotonin reuptake and increase serotonin stimulation of somatodendritic 5-HT1A and terminal autoreceptors. Chronic use leads to desensitization of somatodendritic 5-HT1A and terminal autoreceptors. The overall clinical effect of increased mood and decreased anxiety is thought to be due to adaptive changes in neuronal function that leads to enhanced serotonergic neurotransmission. Side effects include dry mouth, nausea, dizziness, drowsiness, sexual dysfunction and headache (see Toxicity section below for a complete listing of side effects). Side effects generally occur during the first two weeks of therapy and are usually less severe and frequent than those observed with tricyclic antidepressants. Paroxetine hydrochloride and mesylate are considered therapeutic alternatives rather than generic equivalents by the US Food and Drug Administration (FDA); both agents contain the same active moiety (i.e. paroxetine), but are formulated as different salt forms. Clinical studies establishing the efficacy of paroxetine in various conditions were performed using paroxetine hydrochloride. Since both agents contain the same active moiety, the clinical efficacy of both agents is thought to be similar. Paroxetine may be used to treat major depressive disorder (MDD), panic disorder with or without agoraphobia, obsessive-compulsive disorder (OCD), social anxiety disorder (social phobia), generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD) and premenstrual dysphoric disorder (PMDD). Paroxetine has the most evidence supporting its use for anxiety-related disorders of the SSRIs. It has the greatest anticholinergic activity of the agents in this class and compared to other SSRIs, paroxetine may cause greater weight gain, sexual dysfunction, sedation and constipation.

Cyclizine
Cyclizine is only found in individuals that have used or taken this drug. It is a histamine H1 antagonist given by mouth or parenterally for the control of postoperative and drug-induced vomiting and in motion sickness. (From Martindale, The Extra Pharmacopoeia, 30th ed, p935)Vomiting (emesis) is essentially a protective mechanism for removing irritant or otherwise harmful substances from the upper GI tract. Emesis or vomiting is controlled by the vomiting centre in the medulla region of the brain, an important part of which is the chemotrigger zone (CTZ). The vomiting centre possesses neurons which are rich in muscarinic cholinergic and histamine containing synapses. These types of neurons are especially involved in transmission from the vestibular apparatus to the vomiting centre. Motion sickness principally involves overstimulation of these pathways due to various sensory stimuli. Hence the action of cyclizine which acts to block the histamine receptors in the vomiting centre and thus reduce activity along these pathways. Furthermore since cyclizine possesses anti-cholinergic properties as well, the muscarinic receptors are similarly blocked.

Sufentanil
Sufentanil is only found in individuals that have used or taken this drug. It is an opioid analgesic that is used as an adjunct in anesthesia, in balanced anesthesia, and as a primary anesthetic agent. [PubChem]Opiate receptors are coupled with G-protein receptors and function as both positive and negative regulators of synaptic transmission via G-proteins that activate effector proteins. Binding of the opiate stimulates the exchange of GTP for GDP on the G-protein complex. As the effector system is adenylate cyclase and cAMP located at the inner surface of the plasma membrane, opioids decrease intracellular cAMP by inhibiting adenylate cyclase. Subsequently, the release of nociceptive neurotransmitters such as substance P, GABA, dopamine, acetylcholine and noradrenaline is inhibited. Opioids also inhibit the release of vasopressin, somatostatin, insulin and glucagon. Sufentanils analgesic activity is, most likely, due to its conversion to morphine. Opioids open calcium-dependent inwardly rectifying potassium channels (OP1 receptor agonist). This results in hyperpolarization and reduced neuronal excitability.

Tamsulosin
Tamsulosin is a selective antagonist at alpha-1A and alpha-1B-adrenoceptors in the prostate, prostatic capsule, prostatic urethra, and bladder neck. At least three discrete alpha1-adrenoceptor subtypes have been identified: alpha-1A, alpha-1B and alpha-1D; their distribution differs between human organs and tissue. Approximately 70\\\% of the alpha1-receptors in human prostate are of the alpha-1A subtype. Blockage of these receptors causes relaxation of smooth muscles in the bladder neck and prostate.

N-Acetylhistidine
N-Acetyl-L-histidine or N-Acetylhistidine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetylhistidine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetylhistidine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-histidine. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\% of all human proteins and 68\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylhistidine can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free histidine can also occur. In particular, N-Acetylhistidine can be biosynthesized from L-histidine and acetyl-CoA by the enzyme histidine N-acetyltransferase (EC 2.3.1.33). Many N-acetylamino acids are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). Constituent of the tissues of various fish and amphibian subspecies N-Acetylhistidine is found in fishes. KEIO_ID A073

Guanosine monophosphate
Guanosine monophosphate (GMP), also known as 5′-guanidylic acid or guanylic acid (conjugate base guanylate), is a nucleotide that is used as a monomer in RNA. It is an ester of phosphoric acid with the nucleoside guanosine. GMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase guanine; hence it is a ribonucleoside monophosphate. Guanosine monophosphate is commercially produced by microbial fermentation. Guanosine monophosphate, also known as guanylic acid or 5-GMP, belongs to the class of organic compounds known as purine ribonucleoside monophosphates. These are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. A guanine nucleotide containing one phosphate group esterified to the sugar moiety and found widely in nature. Guanosine monophosphate exists in all living species, ranging from bacteria to humans. Within humans, guanosine monophosphate participates in a number of enzymatic reactions. In particular, guanosine triphosphate and guanosine monophosphate can be biosynthesized from diguanosine tetraphosphate through its interaction with the enzyme bis(5-nucleosyl)-tetraphosphatase [asymmetrical]. In addition, guanosine monophosphate can be biosynthesized from guanosine diphosphate; which is mediated by the enzyme ectonucleoside triphosphate diphosphohydrolase 5. In humans, guanosine monophosphate is involved in the metabolic disorder called the lesch-nyhan syndrome (lns) pathway. Outside of the human body, guanosine monophosphate has been detected, but not quantified in several different foods, such as common cabbages, tea, winter squash, spearmints, and sugar apples. Guanosine-5-monophosphate, also known as 5-gmp or guanylic acid, is a member of the class of compounds known as purine ribonucleoside monophosphates. Purine ribonucleoside monophosphates are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. Guanosine-5-monophosphate is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Guanosine-5-monophosphate can be found in a number of food items such as mustard spinach, swiss chard, watercress, and colorado pinyon, which makes guanosine-5-monophosphate a potential biomarker for the consumption of these food products. Guanosine-5-monophosphate can be found primarily in blood and saliva, as well as throughout most human tissues. Guanosine-5-monophosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine-5-monophosphate is involved in several metabolic pathways, some of which include clarithromycin action pathway, erythromycin action pathway, minocycline action pathway, and tetracycline action pathway. Guanosine-5-monophosphate is also involved in several metabolic disorders, some of which include gout or kelley-seegmiller syndrome, xanthine dehydrogenase deficiency (xanthinuria), aICA-Ribosiduria, and molybdenum cofactor deficiency. Guanosine monophosphate is known as E number reference E626.[7] In the form of its salts, such as disodium guanylate (E627), dipotassium guanylate (E628) and calcium guanylate (E629), are food additives used as flavor enhancers to provide the umami taste.[7] It is often used in synergy with disodium inosinate; the combination is known as disodium 5′-ribonucleotides. Disodium guanylate is often found in instant noodles, potato chips and snacks, savoury rice, tinned vegetables, cured meats, and packet soup. As it is a fairly expensive additive, it is usually not used independently of glutamic acid or monosodium glutamate (MSG), which also contribute umami. If inosinate and guanylate salts are present in a list of ingredients but MSG does not appear to be, the glutamic acid is likely provided as part of another ingredient, such as a processed soy protein complex (hydrolyzed soy protein), autolyzed yeast, or soy sauce. 5'-Guanylic acid (5'-GMP) is involved in several metabolic disorders, including the AICA-ribosiduria pathway, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (aprt), and the 2-hydroxyglutric aciduria pathway. 5'-Guanylic acid (5'-GMP) is involved in several metabolic disorders, including the AICA-ribosiduria pathway, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (aprt), and the 2-hydroxyglutric aciduria pathway.

Ethanolamine
Ethanolamine (MEA), also known as monoethanolamine, aminoethanol or glycinol, belongs to the class of organic compounds known as 1,2-aminoalcohols (or simply aminoalcohols). These are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Ethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia. In pharmaceutical formulations, ethanolamine is used primarily for buffering or preparation of emulsions. Ethanolamine can also be used as pH regulator in cosmetics. Biologically, ethanolamine is an initial precursor for the biosynthesis of two primary phospholipid classes, phosphatidylcholine (PC) and phosphatidylethanolamine (PE). In this regard, ethanolamine is the second-most-abundant head group for phospholipids. Ethanolamine serves as a precursor for a variety of N-acylethanolamines (NAEs). These are molecules that modulate several animal and plant physiological processes such as seed germination, plant–pathogen interactions, chloroplast development and flowering (PMID: 30190434). Ethanolamine, when combined with arachidonic acid (C20H32O2; 20:4, ω-6), can also form the endocannabinoid anandamide. Ethanolamine can be converted to phosphoethanolamine via the enzyme known as ethanolamine kinase. the two substrates of this enzyme are ATP and ethanolamine, whereas its two products are ADP and O-phosphoethanolamine. In most plants ethanolamine is biosynthesized by decarboxylation of serine via a pyridoxal 5-phosphate-dependent l-serine decarboxylase (SDC). Ethanolamine exists in all living species, ranging from bacteria to plants to humans.

Lipoamide
Lipoamide is a trivial name for 6,8-dithiooctanoic amide. It is 6,8-dithiooctanoic acids functional form where the carboxyl group is attached to protein (or any other amine) by an amide linkage (containing -NH2) to an amino group. Lipoamide forms a thioester bond, oxidizing the disulfide bond, with acetaldehyde (pyruvate after it has been decarboxylated). It then transfers the acetaldehyde group to CoA which can then continue in the TCA cycle. Lipoamide is an intermediate in glycolysis/gluconeogenesis, citrate cycle (TCA cycle), alanine, aspartate and pyruvate metabolism, and valine, leucine and isoleucine degradation (KEGG:C00248). It is generated from dihydrolipoamide via the enzyme dihydrolipoamide dehydrogenase (EC:1.8.1.4) and then converted to S-glutaryl-dihydrolipoamide via the enzyme oxoglutarate dehydrogenase (EC:1.2.4.2). Lipoamide is the oxidized form of glutathione. (PMID:8957191) KEIO_ID L031; [MS2] KO009031 KEIO_ID L031
N(6)-Methyllysine
N(6)-Methyllysine is a naturally occurring amino acid found in human biofluids. N-monomethyl-lysine is generated by metabolic transmethylation of endogenous lysine. Lysine methylation displays the highest degree of complexity among known covalent histone modifications, with each site of methylation regulating the association of different effector molecules. The versatility of lysine methylation marks is perhaps best exemplified by modifications implicated in transcriptional regulation as well as being required for double-strand break repair in several organisms. Identification of the numerous biological functions encoded by histone lysine methylation is a major area of research interest, as these mechanisms are intimately associated with cellular senescence, genomic instability, and leukemogenesis. While multiple sites of lysine methylation have been linked with gene activation, each modification is distributed to unique positions across the active gene. (PMID: 17030614, 1122639, 15756599, 3111294). N(6)-Methyllysine is a naturally occurring amino acid found in human biofluids.

D-ribulose-1,5-bisphosphate
D-ribulose-1,5-bisphosphate, also known as ribulose-1,5-diphosphoric acid or ribulose-1,5 diphosphate, (D)-isomer, is a member of the class of compounds known as pentose phosphates. Pentose phosphates are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. D-ribulose-1,5-bisphosphate is soluble (in water) and a moderately acidic compound (based on its pKa). D-ribulose-1,5-bisphosphate can be found in a number of food items such as bamboo shoots, bog bilberry, chestnut, and other cereal product, which makes D-ribulose-1,5-bisphosphate a potential biomarker for the consumption of these food products. D-ribulose-1,5-bisphosphate may be a unique E.coli metabolite. Ribulose 1,5-bisphosphate (RuBP) is an organic substance that is involved in photosynthesis. It is a colourless anion, a double phosphate ester of the ketopentose (ketone-containing sugar with five carbon atoms) called ribulose. Salts of RuBP can be isolated, but its crucial biological function happens in solution. To simplify the presentation, the image in the above table depicts the acid form of this anion . KEIO_ID R005

Clupanodonic acid
Docosapentaenoic acid (also known as clupanodonic acid) is an essential omega-3 fatty acid (EFA) which is prevalent in fish oils. Docosapentaenoic acid, commonly called DPA, is an intermediary between eicosapentaenoic acid (EPA, 20:5 ω-3) and docosahexaenoic acid (DHA, 22:6 ω-3). Seal oil is a rich source. There are three functions of docosapentaenoic acid. The most important is as part of phospholipids in all animal cellular membranes: a deficiency of docosapentaenoic acid leads to faulty membranes being formed. A second is in the transport and oxidation of cholesterol: clupanodonic acid tends to lower plasma cholesterol. A third function is as a precursor of prostanoids which are only formed from docosapentaenoic acid. Deficiency of this in experimental animals causes lesions mainly attributable to faulty cellular membranes: sudden failure of growth, lesions of skin and kidney and connective tissue, erythrocyte fragility, impaired fertility, uncoupling of oxidation and phosphorylation. In man pure deficiency of docosapentaenoic acid has been studied particularly in persons fed intravenously. A relative deficiency (that is, a low ratio in the body of docosapentaenoic to long-chain saturated fatty acids and isomers of docosapentaenoate) is common on Western diets and plays an important part in the causation of atherosclerosis, coronary thrombosis, multiple sclerosis, the triopathy of diabetes mellitus, hypertension and certain forms of malignant disease. Various factors affect the dietary requirement of docosapentaenoic acid. (PMID: 6469703) [HMDB]. 7Z,10Z,13Z,16Z,19Z-Docosapentaenoic acid is found in many foods, some of which are green zucchini, green bell pepper, green bean, and red bell pepper.

Cyanidin 3-glucoside
Cyanidin 3-glucoside, also known as chrysanthenin or cyanidin 3-glucoside chloride (CAS: 7084-24-4), belongs to the class of organic compounds known as pyranones and derivatives. Pyranones and derivatives are compounds containing a pyran ring which bears a ketone. Cyanidin 3-glucoside is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, cyanidin 3-glucoside is found, on average, in the highest concentration within a few different foods, such as black elderberries, rubus (blackberry, raspberry), and bilberries and in a lower concentration in redcurrants, strawberries, and sweet oranges. Cyanidin 3-glucoside has also been detected, but not quantified in, several different foods, such as common pea, peaches, Tartary buckwheats, soft-necked garlic, and fats and oils. This could make cyanidin 3-glucoside a potential biomarker for the consumption of these foods. Cyanidin (and its glycosides) is the most commonly occurring of the anthocyanins, a widespread group of pigments responsible for the red-blue colour of many fruits and vegetables (PMID: 14711454). BioTransformer predicts that cyanidin 3-glucoside is a product of cyanidin 3-sophoroside metabolism via a glycoside-hydrolysis reaction occurring in human gut microbiota and catalyzed by the EC.3.2.1.X enzyme (PMID: 30612223). Acquisition and generation of the data is financially supported in part by CREST/JST. Found in many plants and fruits, e.g. cherries, olives and grapes
Canthaxanthin
Canthaxanthin, also known as Cantaxanthin, Cantaxanthine, or Canthaxanthine is a keto-carotenoid, a pigment widely distributed in nature. Carotenoids belong to a larger class of phytochemicals known as terpenoids. Canthaxanin is also classified as a xanthophyll. Xanthophylls are yellow pigments and form one of two major divisions of the carotenoid group; the other division is formed by the carotenes. Both are carotenoids. Xanthophylls and carotenes are similar in structure, but xanthophylls contain oxygen atoms while carotenes are purely hydrocarbons, which do not contain oxygen. Their content of oxygen causes xanthophylls to be more polar (in molecular structure) than carotenes and causes their separation from carotenes in many types of chromatography. (Carotenes are usually more orange in color than xanthophylls. Canthaxanthin is naturally found in bacteria, algae and some fungi. Canthaxanthin is associated with E number E161g and is approved for use as a food coloring agent in different countries, including the United States and the EU. Canthaxanthin is used as poultry feed additive to yield red color in skin and yolks. The European Union permits the use of canthaxanthin in feedstuff at a maximum content of 25 mg/kg of final feedstuff while the United States allows the use of this pigment in broiler chicken and salmonid fish feeds. Canthoxanthin was first isolated in edible chanterelle mushroom (Cantharellus cinnabarinus), from which it derived its name. It has also been found in green algae, bacteria, archea (a halophilic archaeon called Haloferax alexandrines), fungi and bioaccumulates in tissues and egg yolk from wild birds and at low levels in crustaceans and fish such as carp, golden grey mullet, and seabream. Canthaxanthin is not found in wild Atlantic Salmon, but is a minor carotenoid in Pacific Salmon. Canthaxanthin is used in farm-raised trout to give a red/orange color to their flesh similar to wild trout. Canthaxanthin has been used as a food additive for egg yolk, in cosmetics and as a pigmenting agent for human skin applications. It has also been used as a feed additive in fish and crustacean farms. Canthaxanthin is a potent lipid-soluble antioxidant (PMID: 2505240). Canthaxanthin increases resistance to lipid peroxidation primarily by enhancing membrane alpha-tocopherol levels and secondarily by providing weak direct antioxidant activity. Canthaxanthin biosynthesis in bacteria and algae proceeds from beta-carotene via the action of an enzyme known as a beta-carotene ketolase, that is able to add a carbonyl group to carbon 4 and 4 of the beta carotene molecule. Food colouring. Constituent of the edible mushroom (Cantharellus cinnabarinus), sea trout, salmon and brine shrimp. It is used in broiler chicken feed to enhance the yellow colour of chicken skin D020011 - Protective Agents > D000975 - Antioxidants > D002338 - Carotenoids
Tubocurarine
Tubocurarine is only found in individuals that have used or taken this drug. It is a neuromuscular blocker and active ingredient in curare; plant based alkaloid of Menispermaceae. [PubChem]Tubocurarine, the chief alkaloid in tobacco products, binds stereo-selectively to nicotinic-cholinergic receptors at the autonomic ganglia, in the adrenal medulla, at neuromuscular junctions, and in the brain. Two types of central nervous system effects are believed to be the basis of Tubocurarines positively reinforcing properties. A stimulating effect is exerted mainly in the cortex via the locus ceruleus and a reward effect is exerted in the limbic system. At low doses the stimulant effects predominate while at high doses the reward effects predominate. Intermittent intravenous administration of Tubocurarine activates neurohormonal pathways, releasing acetylcholine, norepinephrine, dopamine, serotonin, vasopressin, beta-endorphin, growth hormone, and ACTH.

Resolvin D2
Resolvin D2 is an autacoid resolvin. Autacoids are chemical mediators including the families of resolvins and protectins, defined by their potent bioactions and novel chemical structures. The bioactive local mediators, or autacoids, that require enzymatic generation from the omega-3 essential fatty acid EPA were first identified in resolving inflammatory exudates in vivo and carry potent stereoselective biological actions. Resolvins of the E (RvE) series are derived from eicosapentaenoic acid (EPA). Those derived from docosahexaenoic acid (DHA) were termed resolvins of the D series, for example resolvin D1 (RvD1).Resolvins and protectins have specific stereoselective actions which evoke biological actions in the nanogram range in vivo and are natural exudate products. Resolvins and protectins as distinct chemical families join the lipoxins as potent agonists of endogenous anti-inflammation and are proresolving chemical mediators of interest in human disease as potential new approaches to treatment. The term resolvins (resolution-phase interaction products) was first introduced to signify that these new structures were endogenous mediators, biosynthesized in the resolution phase of inflammatory exudates, possessing very potent anti-inflammatory and immunoregulatory actions. These actions include reducing neutrophil traffic, regulating cytokine and reactive oxygen species, and lowering the magnitude of the response. In recent years, investigators have recognized inflammation as playing a key role in many prevalent diseases not previously considered to be of inflammatory etiology. These include Alzheimers disease, cardiovascular disease, and cancer, which now join those well-appreciated inflammatory disorders such as arthritis and periodontal disease. Identifying the molecular mechanism(s) that underlie the many reports of the benefits of dietary omega-3 PUFAs remains an important challenge for nutrition and medicine. Thus, that these new mediator families, resolvins and protectins, are biosynthesized from EPA and DHA, act locally, and possess potent, novel bioactions is of interest to researchers.

Retinol(Vitamin A)
Vitamin A (retinol) is a yellow fat-soluble, antioxidant vitamin important in vision and bone growth. It belongs to the family of chemical compounds known as retinoids. Retinol is ingested in a precursor form; animal sources (milk and eggs) contain retinyl esters, whereas plants (carrots, spinach) contain pro-vitamin A carotenoids. Hydrolysis of retinyl esters results in retinol while pro-vitamin A carotenoids can be cleaved to produce retinal. Retinal, also known as retinaldehyde, can be reversibly reduced to produce retinol or it can be irreversibly oxidized to produce retinoic acid. Retinol and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response. Dietary vitamin A is derived from a variety of carotenoids found in plants. It is enriched in the liver, egg yolks, and the fat component of dairy products. Retinyl esters from animal-sourced foods (or synthesized for dietary supplements for humans and domesticated animals) are acted upon by retinyl ester hydrolases in the lumen of the small intestine to release free retinol. Retinol enters intestinal absorptive cells by passive diffusion. Absorption efficiency is in the range of 70 to 90\%. Humans are at risk for acute or chronic vitamin A toxicity because there are no mechanisms to suppress absorption or excrete the excess in urine.[5] Within the cell, retinol is there bound to retinol binding protein 2 (RBP2). It is then enzymatically re-esterified by the action of lecithin retinol acyltransferase and incorporated into chylomicrons that are secreted into the lymphatic system. Unlike retinol, β-carotene is taken up by enterocytes by the membrane transporter protein scavenger receptor B1 (SCARB1). The protein is upregulated in times of vitamin A deficiency. If vitamin A status is in the normal range, SCARB1 is downregulated, reducing absorption.[6] Also downregulated is the enzyme beta-carotene 15,15'-dioxygenase (formerly known as beta-carotene 15,15'-monooxygenase) coded for by the BCMO1 gene, responsible for symmetrically cleaving β-carotene into retinal.[8] Absorbed β-carotene is either incorporated as such into chylomicrons or first converted to retinal and then retinol, bound to RBP2. After a meal, roughly two-thirds of the chylomicrons are taken up by the liver with the remainder delivered to peripheral tissues. Peripheral tissues also can convert chylomicron β-carotene to retinol.[6][15] The capacity to store retinol in the liver means that well-nourished humans can go months on a vitamin A deficient diet without manifesting signs and symptoms of deficiency. Two liver cell types are responsible for storage and release: hepatocytes and hepatic stellate cells (HSCs). Hepatocytes take up the lipid-rich chylomicrons, bind retinol to retinol-binding protein 4 (RBP4), and transfer the retinol-RBP4 to HSCs for storage in lipid droplets as retinyl esters. Mobilization reverses the process: retinyl ester hydrolase releases free retinol which is transferred to hepatocytes, bound to RBP4, and put into blood circulation. Other than either after a meal or when consumption of large amounts exceeds liver storage capacity, more than 95\% of retinol in circulation is bound to RBP4.[15] Vitamin A is a fat-soluble vitamin, hence an essential nutrient. The term "vitamin A" encompasses a group of chemically related organic compounds that includes retinol, retinal (also known as retinaldehyde), retinoic acid, and several provitamin (precursor) carotenoids, most notably beta-carotene.[3][4][5][6] Vitamin A has multiple functions: essential in embryo development for growth, maintaining the immune system, and healthy vision, where it combines with the protein opsin to form rhodopsin – the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision.[7] Vitamin A occurs as two principal forms in foods: A) retinol, found in animal-sourced foods, either as retinol or bound to a fatty acid to become a retinyl ester, and B) the carotenoids alpha-carotene, β-carotene, gamma-carotene, and the xanthophyll beta-cryptoxanthin (all of which contain β-ionone rings) that function as provitamin A in herbivore and omnivore animals which possess the enzymes that cleave and convert provitamin carotenoids to retinal and then to retinol.[8] Some carnivore species lack this enzyme. The other carotenoids have no vitamin activity.[6] Dietary retinol is absorbed from the digestive tract via passive diffusion. Unlike retinol, β-carotene is taken up by enterocytes by the membrane transporter protein scavenger receptor B1 (SCARB1), which is upregulated in times of vitamin A deficiency.[6] Storage of retinol is in lipid droplets in the liver. A high capacity for long-term storage of retinol means that well-nourished humans can go months on a vitamin A- and β-carotene-deficient diet, while maintaining blood levels in the normal range.[4] Only when the liver stores are nearly depleted will signs and symptoms of deficiency show.[4] Retinol is reversibly converted to retinal, then irreversibly to retinoic acid, which activates hundreds of genes.[9] Vitamin A deficiency is common in developing countries, especially in Sub-Saharan Africa and Southeast Asia. Deficiency can occur at any age but is most common in pre-school age children and pregnant women, the latter due to a need to transfer retinol to the fetus. Vitamin A deficiency is estimated to affect approximately one-third of children under the age of five around the world, resulting in hundreds of thousands of cases of blindness and deaths from childhood diseases because of immune system failure.[10] Reversible night blindness is an early indicator of low vitamin A status. Plasma retinol is used as a biomarker to confirm vitamin A deficiency. Breast milk retinol can indicate a deficiency in nursing mothers. Neither of these measures indicates the status of liver reserves.[6] The European Union and various countries have set recommendations for dietary intake, and upper limits for safe intake. Vitamin A toxicity also referred to as hypervitaminosis A, occurs when there is too much vitamin A accumulating in the body. Symptoms may include nervous system effects, liver abnormalities, fatigue, muscle weakness, bone and skin changes, and others. The adverse effects of both acute and chronic toxicity are reversed after consumption of high dose supplements is stopped.[6]

O-xylenes are aromatic compounds that contain a o-xylene moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 2-positions. 1,2-dimethylbenzene is a geranium tasting compound found in black walnut and papaya, which makes 1,2-dimethylbenzene a potential biomarker for the consumption of these food products. 1,2-dimethylbenzene can be found primarily in blood, feces, and saliva. 1,2-dimethylbenzene exists in all eukaryotes, ranging from yeast to humans. 1,2-dimethylbenzene is formally rated as an unfounded non-carcinogenic (IARC 3) potentially toxic compound. o-Xylene (ortho-xylene) is an aromatic hydrocarbon with the formula C6H4(CH3)2. with two methyl substituents bonded to adjacent carbon atoms of a benzene ring (the ortho configuration). It is a constitutional isomer of m-xylene and p-xylene, the mixture being called xylene or xylenes. o-Xylene is a colorless slightly oily flammable liquid . If the compound has been ingested, rapid gastric lavage should be performed using 5\\% sodium bicarbonate. For skin contact, the skin should be washed with soap and water. If the compound has entered the eyes, they should be washed with large quantities of isotonic saline or water. In serious cases, atropine and/or pralidoxime should be administered. Anti-cholinergic drugs work to counteract the effects of excess acetylcholine and reactivate AChE. Atropine can be used as an antidote in conjunction with pralidoxime or other pyridinium oximes (such as trimedoxime or obidoxime), though the use of -oximes has been found to be of no benefit, or possibly harmful, in at least two meta-analyses. Atropine is a muscarinic antagonist, and thus blocks the action of acetylcholine peripherally (T3DB). o-Xylene belongs to the family of Toluenes. These are compounds containing a benzene ring which bears a methane group.
Tetrahydrofolic acid
Tetrahydrofolate is a soluble coenzyme (vitamin B9) that is synthesized de novo by plants and microorganisms, and absorbed from the diet by animals. It is composed of three distinct parts: a pterin ring, a p-ABA (p-aminobenzoic acid) and a polyglutamate chain with a number of residues varying between 1 and 8. Only the tetra-reduced form of the molecule serves as a coenzyme for C1 transfer reactions. In biological systems, the C1-units exist under various oxidation states and the different tetrahydrofolate derivatives constitute a family of related molecules named indistinctly under the generic term folate. (PMID 16042593). Folate is important for cells and tissues that rapidly divide. Cancer cells divide rapidly, and drugs that interfere with folate metabolism are used to treat cancer. Methotrexate is a drug often used to treat cancer because it inhibits the production of the active form, tetrahydrofolate. Unfortunately, methotrexate can be toxic, producing side effects such as inflammation in the digestive tract that make it difficult to eat normally. -- Wikipedia; Signs of folic acid deficiency are often subtle. Diarrhea, loss of appetite, and weight loss can occur. Additional signs are weakness, sore tongue, headaches, heart palpitations, irritability, and behavioral disorders. Women with folate deficiency who become pregnant are more likely to give birth to low birth weight and premature infants, and infants with neural tube defects. In adults, anemia is a sign of advanced folate deficiency. In infants and children, folate deficiency can slow growth rate. Some of these symptoms can also result from a variety of medical conditions other than folate deficiency. It is important to have a physician evaluate these symptoms so that appropriate medical care can be given. -- Wikipedia; Folinic acid is a form of folate that can help rescue or reverse the toxic effects of methotrexate. Folinic acid is not the same as folic acid. Folic acid supplements have little established role in cancer chemotherapy. There have been cases of severe adverse effects of accidental substitution of folic acid for folinic acid in patients receiving methotrexate cancer chemotherapy. It is important for anyone receiving methotrexate to follow medical advice on the use of folic or folinic acid supplements. -- Wikipedia. Low concentrations of folate, vitamin B12, or vitamin B6 may increase the level of homocysteine, an amino acid normally found in blood. There is evidence that an elevated homocysteine level is an independent risk factor for heart disease and stroke. The evidence suggests that high levels of homocysteine may damage coronary arteries or make it easier for blood clotting cells called platelets to clump together and form a clot. However, there is currently no evidence available to suggest that lowering homocysteine with vitamins will reduce your risk of heart disease. Clinical intervention trials are needed to determine whether supplementation with folic acid, vitamin B12 or vitamin B6 can lower your risk of developing coronary heart disease. -- Wikipedia.

5,10-Methylene-THF
5,10-Methylene-THF is an intermediate in glycine, serine and threonine metabolism and one carbon metabolism. 5,10-CH2-THF can also be used as a coenzyme in the biosynthesis of thymidine. More specifically it is the C1-donor in the reactions catalyzed by thymidylate synthase and thymidylate synthase (FAD). It also acts as a coenzyme in the synthesis of serine from glycine via the enzyme serine hydroxymethyl transferase. 5,10-Methylene-THF is a substrate for Methylenetetrahydrofolate reductase. This enzyme converts 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate. This reaction is required for the multistep process that converts the amino acid homocysteine to methionine. The body uses methionine to make proteins and other important compounds. 5,10-CH2-THF is a substrate for many enzymes including Bifunctional methylenetetrahydrofolate dehydrogenase/cyclohydrolase (mitochondrial), Aminomethyltransferase (mitochondrial), Serine hydroxymethyltransferase (mitochondrial), Methylenetetrahydrofolate reductase, C-1-tetrahydrofolate synthase (cytoplasmic), Serine hydroxymethyltransferase (cytosolic) and Thymidylate synthase. 5,10-Methylene-THF is an intermediate in the metabolism of Methane and the metabolism of Nitrogen.

Hydrogen
Hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. With an atomic weight of 1.00794, hydrogen is the lightest element. Besides the common H1 isotope, hydrogen exists as the stable isotope Deuterium and the unstable, radioactive isotope Tritium. Hydrogen is the most abundant of the chemical elements, constituting roughly 75\\% of the universes elemental mass. Hydrogen can form compounds with most elements and is present in water and most organic compounds. It plays a particularly important role in acid-base chemistry, in which many reactions involve the exchange of protons between soluble molecules. Oxidation of hydrogen, in the sense of removing its electron, formally gives H+, containing no electrons and a nucleus which is usually composed of one proton. That is why H+ is often called a proton. This species is central to discussion of acids. Under the Bronsted-Lowry theory, acids are proton donors, while bases are proton acceptors. A bare proton H+ cannot exist in solution because of its strong tendency to attach itself to atoms or molecules with electrons. However, the term proton is used loosely to refer to positively charged or cationic hydrogen, denoted H+. H2 is a product of some types of anaerobic metabolism and is produced by several microorganisms, usually via reactions catalyzed by iron- or nickel-containing enzymes called hydrogenases. These enzymes catalyze the reversible redox reaction between H2 and its component two protons and two electrons. Creation of hydrogen gas occurs in the transfer of reducing equivalents produced during pyruvate fermentation to water. Hydrogen has been found to be a metabolite of Citrobacter, Cyanobacteria, Enterobacter, Halobacterium and Rhodobacteraceae (PMID: 28042989; PMID: 16371161) (https://www.insa.nic.in/writereaddata/UpLoadedFiles/PINSA/Vol51B_1985_2_Art16.pdf) (https://www.researchgate.net/publication/222428793_High_Hydrogen_Yield_from_a_Two-step_Process_of_Dark-_and_Photo-fermentation_of_Sucrose) (Tao, Y; Chen, Y; Wu, Y; He, Y; Zhou, Z (2007). "High hydrogen yield from a two-step process of dark- and photo-fermentation of sucrose". International Journal of Hydrogen Energy. 32 (2): 200-206). It is used as a packaging gas [DFC]
CDP-ethanolamine
CDP-ethanolamine, also known as cytidine 5’-diphosphoethanolamine, belongs to the class of organic compounds known as CDP-ethanolamines. These are phosphoethanolamines that consist of an ethanolamine having a cytidine 5-diphosphate moiety attached to the oxygen. CDP-ethanolamine is a very strong basic compound (based on its pKa). In humans, CDP-ethanolamine is involved in phosphatidylethanolamine biosynthesis. Outside of the human body, CDP-ethanolamine has been detected, but not quantified in, several different foods, such as Chinese water chestnuts, buffalo currants, red huckleberries, eggplants, and brazil nuts. This could make CDP-ethanolamine a potential biomarker for the consumption of these foods. Cytidine is a molecule (known as a nucleoside) that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a beta-N1-glycosidic bond. [HMDB]. CDP-Ethanolamine is found in many foods, some of which are allspice, hedge mustard, wasabi, and green vegetables.
Chloride ion
Under standard conditions, chlorine exists as a diatomic molecule. Chlorine is a highly toxic, pale yellow-green gas that has a specific strong smell. In nature, chlorine is most abundant as a chloride ion. Physiologically, it exists as an ion in the body. The chloride ion is an essential anion that the body needs for many critical functions. It also helps keep the bodys acid-base balance. The amount of chloride in the blood is carefully controlled by the kidneys. Chloride ions have important physiological roles. For instance, in the central nervous system, the inhibitory action of glycine and some of the action of GABA relies on the entry of Cl- into specific neurons. Also, the chloride-bicarbonate exchanger biological transport protein relies on the chloride ion to increase the bloods capacity of carbon dioxide, in the form of the bicarbonate ion. Chloride-transporting proteins (CLC) play fundamental roles in many tissues in the plasma membrane as well as in intracellular membranes. CLC proteins form a gene family that comprises nine members in mammals, at least four of which are involved in human genetic diseases. GABA(A) receptors are pentameric complexes that function as ligand-gated chloride ion channels. WNK kinases are a family of serine-threonine kinases that have been shown to play an essential role in the regulation of electrolyte homeostasis, and they are found in diverse epithelia throughout the body that are involved in chloride ion flux. Cystic fibrosis (CF) is caused by alterations in the CF transmembrane conductance regulator (CFTCR) gene that result in deranged sodium and chloride ion transport channels. (PMID: 17539703, 17729441, 17562499, 15300163) (For a complete review see Evans, Richard B. Chlorine: state of the art. Lung (2005), 183(3), 151-167. PMID: 16078037). The chloride ion is formed when the element chlorine picks up one electron to form the Cl- anion. The chloride ion is one of the most common anions in nature and is necessary to most forms of life. It is an essential electrolyte responsible for maintaining acid/base balance and regulating fluid in and out of cells. [Wikipedia]. Chloride is found in many foods, some of which are jute, grapefruit, lentils, and lime.
7-Dehydrocholesterol
7-Dehydrocholesterol (7-DHC), also known as provitamin D3 or 5,7-cholestadien-3-b-ol, belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 7-dehydrocholesterol is also classified as a sterol. 7-Dehydrocholesterol is known as a zoosterol, meaning that it is a sterol isolated from animals (to distinguish those sterols isolated from plants which are called phytosterols). 7-DHC functions in the serum as a cholesterol precursor and is photochemically converted to vitamin D3 in the skin. Therefore 7-DHC functions as provitamin-D3. The presence of 7-DHC in human skin enables humans and other mammals to manufacture vitamin D3 (cholecalciferol) from ultraviolet rays in the sun light, via an intermediate isomer pre-vitamin D3. 7-DHC absorbs UV light most effectively at wavelengths between 290 and 320 nm and, thus, the production of vitamin D3 will occur primarily at those wavelengths (PMID: 9625080). The two most important factors that govern the generation of pre-vitamin D3 are the quantity (intensity) and quality (appropriate wavelength) of the UVB irradiation reaching the 7-dehydrocholesterol deep in the stratum basale and stratum spinosum (PMID: 9625080). 7-DHC is also found in the milk of several mammalian species, including cows (PMID: 10999630; PMID: 225459). It was discovered by Nobel-laureate organic chemist Adolf Windaus. 7-DHC can be produced by animals and plants via different pathways (PMID: 23717318). It is not produced by fungi in significant amounts. 7-DHC is made by some algae and can also be produced by some bacteria. 7-Dehydrocholesterol is a zoosterol (a sterol produced by animals rather than plants). It is a provitamin-D. The presence of this compound in skin enables humans to manufacture vitamin D3 from ultra-violet rays in the sun light, via an intermediate isomer provitamin D3. It is also found in breast milk.

3-deoxy-D-manno-octulosonate
3-deoxy-d-manno-octulosonate, also known as kdo or 2-dehydro-3-deoxy-D-octonate, belongs to sugar acids and derivatives class of compounds. Those are compounds containing a saccharide unit which bears a carboxylic acid group. 3-deoxy-d-manno-octulosonate is soluble (in water) and a moderately acidic compound (based on its pKa). 3-deoxy-d-manno-octulosonate can be found in a number of food items such as peppermint, okra, horseradish tree, and hazelnut, which makes 3-deoxy-d-manno-octulosonate a potential biomarker for the consumption of these food products. 3-deoxy-d-manno-octulosonate may be a unique E.coli metabolite.
Bromide
Bromine is a brown or red liquid with a characteristic odor. Bromine is mainly used in the manufacture of dyes, inks, flame retardants, pharmaceuticals and chemical warfare agents. Occupational exposure to bromine may occur during the production and the application of bromine compounds and during other industrial activities. This compound is adsorbed into the human body through the respiratory tract, skin (occupational exposure) and alimentary tract (general population). Physiologically, bromine exists as an ion in the body. Slight eye irritation occurs as a consequence of chronic exposure to bromine vapors at concentration of 1 mg/m3. Higher concentrations increase this effect and cause nasal and skin irritation. Many years observations have shown that during occupational exposure to bromine vapors at concentrations of up to 0.7 mg/m3 (0.1 ppm), there are no observed adverse effects. From cytotoxicity and mutagenicity assays, it is known that brominated organic compounds are more toxic than chlorinated organic compounds. However, only a limited number of brominated organic compounds have been regulated. (PMID: 17316744). Bromine is a brown or red liquid with a characteristic odor.

Sodium
Na+, also known as sodium ion or na(+), is a member of the class of compounds known as homogeneous alkali metal compounds. Homogeneous alkali metal compounds are inorganic compounds containing only metal atoms,with the largest atom being a alkali metal atom. Na+ can be found in a number of food items such as nanking cherry, opium poppy, alpine sweetvetch, and salmonberry, which makes na+ a potential biomarker for the consumption of these food products. Na+ can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine, as well as in human kidney tissue. Na+ exists in all eukaryotes, ranging from yeast to humans. In humans, na+ is involved in several metabolic pathways, some of which include eplerenone action pathway, betaxolol action pathway, furosemide action pathway, and morphine action pathway. Na+ is also involved in several metabolic disorders, some of which include diltiazem action pathway, bendroflumethiazide action pathway, dimethylthiambutene action pathway, and lidocaine (antiarrhythmic) action pathway. NA, N.A., Na, or n/a may refer to: . Sodium ions are necessary for regulation of blood and body fluids, transmission of nerve impulses, heart activity, and certain metabolic functions. Physiologically, it exists as an ion in the body. Sodium is needed by animals, which maintain high concentrations in their blood and extracellular fluids, but the ion is not needed by plants. The human requirement for sodium in the diet is less than 500 mg per day, which is typically less than a tenth as much as many diets "seasoned to taste." Most people consume far more sodium than is physiologically needed. For certain people with salt-sensitive blood pressure, this extra intake may cause a negative effect on health.
Queuine
Queuine is a highly modified derivative of guanine found in the first position of the anticodon of the transfer RNAs for asp, asn, his and tyr. The original transcripts of these tRNAs contain guanine in this position. All organisms with the exception of yeast and mycoplasma contain queuine. Bacteria synthesize queuine but it cannot be synthesized by higher mammals. Significant amounts of free queuine are present in common plant and animal food products.

Retinyl palmitate
Retinyl palmitate, also known as vitamin a palmitate or aquasol a, is a member of the class of compounds known as wax monoesters. Wax monoesters are waxes bearing an ester group at exactly one position. Thus, retinyl palmitate is considered to be an isoprenoid lipid molecule. Retinyl palmitate is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Retinyl palmitate can be found in a number of food items such as rocket salad (sspecies), black elderberry, common grape, and vaccinium (blueberry, cranberry, huckleberry), which makes retinyl palmitate a potential biomarker for the consumption of these food products. Retinyl palmitate can be found primarily in blood, as well as throughout most human tissues. In humans, retinyl palmitate is involved in the retinol metabolism. Retinyl palmitate is also involved in vitamin A deficiency, which is a metabolic disorder. An alternate spelling, retinol palmitate, which violates the -yl organic chemical naming convention for esters, is also frequently seen . Retinyl palmitate, or vitamin A palmitate, is a common vitamin supplement, with formula C36H60O2. It is available in both oral and injectable forms for treatment of vitamin A deficiency, under the brand names Aquasol and Palmitate. Retinyl palmitate is an alternate for retinyl acetate in vitamin A supplements, and is available in oily or dry forms. It is a pre-formed version of vitamin A, and can thus be realistically over-dosed, unlike beta-carotene.

Protochlorophyllide
Protochlorophyllide is found in fruits. Protochlorophyllide is isolated from the seed husks of Cucurbita pepo Chlorophyll itself is bound to proteins and can transfer the absorbed energy in the required direction. Protochlorophyllide, differently, mostly occurs in the free form and under light conditions acts as photosensitizer, forming highly toxic free radicals. Hence plants need an efficient mechanism of regulating the amount of chlorophyll precursor. In angiosperms, this is done at the step of D-Aminolevulinic acid (ALA), one of the intermediate compounds in the biosynthesis pathway. Plants that are fed by ALA accumulate high and toxic levels of protochlorophyllide, so do the mutants with the damaged regulatory system. Despite of numerous past attempts to find the mutant that overacumulates protochlorophyllide under usual conditions, only one such gene (flu) is currently (2009) known. Flu (first described in ) is a nuclear - encoded, chloroplast - located protein that appears containing only protein - protein interaction sites. It is currently not know which other proteins interact through this linker. The regulatory protein is a transmembrane protein that is located in the thylakoid membrane. Later it was discovered that Tigrina mutants in barley, known long time ago, are also mutated in the same gene It is not obvious why no mutants of any other gene were observed; maybe mutations in other proteins, involved into the regulatory chain, are fatal. Flu is a single gene, not a member of the gene family. Protochlorophyllide , more accurate monovinyl protochlorophyllide, is an immediate precursor of chlorophyll a that lacks the phytol side chain of chlorophyll. Unlike chlorophyll, protochlorophyllide is highly fluorescent; mutants that accumulate it glow in red if irradiated by the blue lightIn Angiosperms, the last step, conversion of protochlorophyllide to chlorophyll, is light - dependent and such plants are pale (etiolated) if grown in the darkness. Gymnosperms, algae, and photosynthetic bacteria additionally have another, light - independent enzyme and grow green in the darkness as well. The enzyme that converts protochlorophyllide to chlorophyll is protochlorophyllide reductase , EC 1.3.1.33. There are two structurally unrelated proteins with this activity: the light - dependent and the dark - operative. The light dependent reductase needs light to operate. The dark - operative version is a completely different protein, consisting of three subunits that exhibit significant sequence similarity to the three subunits of nitrogenase, which catalyzes the formation of ammonia from dinitrogen. This enzyme might be evolutionary older but (being similar to nitrogenase) is highly sensitive to free oxygen and does not work if its concentration exceeds about 3 \\%. Hence the alternative, light dependent version needed to evolve

Prostaglandin G2
Prostaglandin G2 (PGG2) is synthesized from arachidonic acid on a cyclooxygenase (COX) metabolic pathway as a primary step; the COX biosynthesis of prostaglandin (PG) begins with the highly specific oxygenation of arachidonic acid in the 11R configuration and ends with a 15S oxygenation to form PGG2. The COX site activity that catalyzes the conversion of arachidonic acid to PGG2 is the target for nonsteroidal antiinflammatory drugs (NSAIDs). The peroxidase site activity catalyzes the two-electron reduction of the hydroperoxide bond of PGG2 to yield the corresponding alcohol prostaglandin H2 (PGH2). The formation of a phenoxyl radical on Tyr385 couples the activities of the two sites. The Tyr385 radical is produced via oxidation by compound I, an oxoferryl porphyrin -cation radical, which is generated by reaction of the hemin resting state with PGG2 or other hydroperoxides. The tyrosyl radical homolytically abstracts the 13proS hydrogen atom of arachidonic acid which initiates a radical cascade that ends with the stereoselective formation of PGG2. PGG2 then migrates from the cyclooxygenase (COX) site to the peroxidase (POX) site where it reacts with the hemin group to generate PGH2 and compound I. The heterolytic oxygen-oxygen bond cleavage is assisted by the conserved distal residues His207 and Gln203, mutation of which has been shown to severely impair enzyme activity. Compound I, upon reaction with Tyr385, gives compound II, which in turn is reduced to the hemin resting state by one-electron oxidation of reducing cosubstrates or undergoes reactions that result in enzyme self-inactivation. Prostaglandin endoperoxide H synthase (PGHS) 1 is a bifunctional membrane enzyme of the endoplasmic reticulum that converts arachidonic acid into prostaglandin H2 (PGH2), the precursor of all prostaglandins, thromboxanes, and prostacyclins. These lipid mediators are intricately involved in normal physiology, namely, in mitogenesis, fever generation, pain response, lymphocyte chemotaxis, fertility, and contradictory stimuli such as vasoconstriction and vasodilatation, as well as platelet aggregation and quiescence. PGHS is implicated in numerous pathologies, including inflammation, cancers of the colon, lung, and breast, Alzheimers disease, Parkinsons disease, and numerous cardiovascular diseases including atherosclerosis, thrombosis, myocardial infarction, and stroke. (PMID: 14594816, 16552393, 16411757). Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. Prostaglandin G2 (PGG2) is synthesized from arachidonic acid on a cyclooxygenase (COX) metabolic pathway as a primary step; the COX biosynthesis of prostaglandin (PG) begins with the highly specific oxygenation of arachidonic acid in the 11R configuration and ends with a 15S oxygenation to form PGG2.

The enzyme 23-cyclic-nucleotide 2-phosphodiesterase (E.C. 3.1.4.16) catalyses the hydrolysis of both 2,3-cyclic AMP and 2,3-cyclic GMP into 3-AMP and 3-GMP, respectively, at the 3-terminal of RNA. 2,3-cyclic phosphate termini are produced, as either intermediates or final products, during RNA cleavage by many different endoribonucleases. The enzyme RNA 3-phosphate cyclase also converts the 3-terminal phosphate in RNA into the 2,3-cyclic phosphodiester in the ATP-dependent reaction which involves formation of the covalent cyclase-AMP and the RNA-N3 pp5 A intermediates (PMID: 10397337). This enzyme could be involved in the maintenance of cyclic ends in tRNA splicing intermediates or in the cyclization of the 3 end of U6 snRNA (PMID: 9184239). Guanosine-2,3-cyclic phosphate is capable of blocking DNA synthesis in vitro (PMID: 7528887). 2, 3-cGMP seems to preferentially stimulate mature T-cells while 3, 5-cGMP preferentially acts on B-cells (PMID: 163786).

Leukotriene F4
Leukotriene F4 is an intermediate in Arachidonic acid metabolism. Leukotriene F4 is converted from Leukotriene E4 via the enzyme Transferases (EC 2.3.2.-).Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. Leukotriene F4 is an intermediate in Arachidonic acid metabolism. Leukotriene F4 is converted from Leukotriene E4 via the enzyme Transferases (EC 2.3.2.-).

Carbenicillin
Carbenicillin is only found in individuals that have used or taken this drug. It is a broad-spectrum semisynthetic penicillin derivative used parenterally. It is susceptible to gastric juice and penicillinase and may damage platelet function. [PubChem]Free carbenicillin is the predominant pharmacologically active fraction of the salt. Carbenicillin exerts its antibacterial activity by interference with final cell wall synthesis of susceptible bacteria. Penicillins acylate the penicillin-sensitive transpeptidase C-terminal domain by opening the lactam ring. This inactivation of the enzyme prevents the formation of a cross-link of two linear peptidoglycan strands, inhibiting the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that carbenicillin interferes with an autolysin inhibitor.

m-Xylene
M-xylene, also known as 1,3-dimethylbenzene or M-xylol, is a member of the class of compounds known as M-xylenes. M-xylenes are aromatic compounds that contain a m-xylene moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 3-positions. M-xylene is a plastic tasting compound found in black walnut, parsley, and safflower, which makes M-xylene a potential biomarker for the consumption of these food products. M-xylene can be found primarily in blood and feces. M-xylene exists in all eukaryotes, ranging from yeast to humans. M-xylene is formally rated as an unfounded non-carcinogenic (IARC 3) potentially toxic compound. m-Xylene (meta-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes. The m- stands for meta-, indicating that the two methyl groups in m-xylene occupy positions 1 and 3 on a benzene ring. It is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o-xylene and p-xylene. All have the same chemical formula C6H4(CH3)2. All xylene isomers are colorless and highly flammable . If the compound has been ingested, rapid gastric lavage should be performed using 5\\% sodium bicarbonate. For skin contact, the skin should be washed with soap and water. If the compound has entered the eyes, they should be washed with large quantities of isotonic saline or water. In serious cases, atropine and/or pralidoxime should be administered. Anti-cholinergic drugs work to counteract the effects of excess acetylcholine and reactivate AChE. Atropine can be used as an antidote in conjunction with pralidoxime or other pyridinium oximes (such as trimedoxime or obidoxime), though the use of -oximes has been found to be of no benefit, or possibly harmful, in at least two meta-analyses. Atropine is a muscarinic antagonist, and thus blocks the action of acetylcholine peripherally (T3DB). m-Xylene, also known as 1,3-xylene or m-dimethylbenzene, belongs to the class of organic compounds known as m-xylenes. These are aromatic compounds that contain a m-xylene moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 3-positions. The conversion m-xylene to isophthalic acid entails catalytic oxidation. m-Xylene (meta-xylene) is an aromatic hydrocarbon. m-Xylene is possibly neutral. m-Xylene is a plastic tasting compound. m-xylene is found, on average, in the highest concentration in safflowers. m-xylene has also been detected, but not quantified, in black walnuts and parsley. This could make m-xylene a potential biomarker for the consumption of these foods. Xylenes are not acutely toxic, for example the LD50 (rat, oral) is 4300 mg/kg. m-Xylene is a potentially toxic compound. Concerns with xylenes focus on narcotic effects. The m- stands for meta-, indicating that the two methyl groups in m-xylene occupy positions 1 and 3 on a benzene ring. All xylene isomers are colorless and highly flammable. Petroleum contains about 1 weight percent xylenes.

Proparacaine
Proparacaine is only found in individuals that have used or taken this drug. It is a topical anesthetic drug of the amino ester group. It is available as its hydrochloride salt in ophthalmic solutions at a concentration of 0.5\\%. [Wikipedia]The exact mechanism whereby proparacaine and other local anesthetics influence the permeability of the cell membrane is unknown; however, several studies indicate that local anesthetics may limit sodium ion permeability through the lipid layer of the nerve cell membrane. Proparacaine may alter epithelial sodium channels through interaction with channel protein residues. This limitation prevents the fundamental change necessary for the generation of the action potential.

Ethosuximide
Ethosuximide is only found in individuals that have used or taken this drug. It is an anticonvulsant especially useful in the treatment of absence seizures unaccompanied by other types of seizures. [PubChem]Binds to T-type voltage sensitive calcium channels. Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1G gives rise to T-type calcium currents. T-type calcium channels belong to the "low-voltage activated (LVA)" group and are strongly blocked by mibefradil. A particularity of this type of channels is an opening at quite negative potentials and a voltage-dependent inactivation. T-type channels serve pacemaking functions in both central neurons and cardiac nodal cells and support calcium signaling in secretory cells and vascular smooth muscle. They may also be involved in the modulation of firing patterns of neurons which is important for information processing as well as in cell growth processes.

Apraclonidine is only found in individuals that have used or taken this drug.Apraclonidine, also known as iopidine, is a sympathomimetic used in glaucoma therapy.Apraclonidine is a relatively selective alpha2 adrenergic receptor agonist that stimulates alpha1 receptors to a lesser extent. It has a peak ocular hypotensive effect occurring at two hours post-dosing. The exact mechanism of action is unknown, but fluorophotometric studies in animals and humans suggest that Apraclonidine has a dual mechanism of action by reducing aqueous humor production through the constriction of afferent ciliary process vessels, and increasing uveoscleral outflow.

Metipranolol
Metipranolol is only found in individuals that have used or taken this drug. It is a beta-adrenergic antagonist effective for both beta-1 and beta-2 receptors. It is used as an antiarrhythmic, antihypertensive, and antiglaucoma agent. [PubChem]Although it is known that metipranolol binds the beta1 and beta2 adrenergic receptors, the mechanism of metipranolols action is not known. It has no significant intrinsic sympathomimetic activity, and has only weak local anesthetic (membrane-stabilizing) and myocardial depressant activity. It appears that the ophthalmic beta-adrenergic blocking agents reduce aqueous humor production, as demonstrated by tonography and fluorophotometry. A slight increase in aqueous humor outflow may be an additional mechanism.

24-Hydroxycholesterol
24-Hydroxycholesterol (24OHC) is almost exclusively formed in the brain. The enzymatic conversion of CNS cholesterol to 24OHC, which readily crosses the blood-brain barrier, is the major pathway for brain cholesterol elimination and brain cholesterol homeostasis maintenance. The enzyme mediating this conversion has been characterized at the molecular level as cholesterol 24-hydroxylase (EC 1.14.13.98, CYP46) and is mainly located in neurons. Like other oxysterols, 24OHC is efficiently converted into normal bile acids or excreted in bile in its sulfated and glucuronidated form. Levels of 24OHC in the circulation decrease with age in infants and children. In adults, however, the levels appear to be stable. There is accumulating evidence pointing toward a potentially important link between cholesterol, beta-amyloid, and Alzheimers disease. Patients with active demyelinating diseases had increased levels of 24OHC in cerebrospinal fluid (CSF). Patients with Alzheimers disease have slightly increased levels of 24OHC in CSF. Patients with multiple sclerosis have a tendency to have higher levels of 24OHC during active periods.

Lipid A
Lipid A is a lipid component of an endotoxin held responsible for toxicity of Gram-negative bacteria. It is the innermost of the three regions of the lipopolysaccharide (LPS, also called endotoxin) molecule, and its hydrophobic nature allows it to anchor the LPS to the outer membrane. While its toxic effects can be damaging, the sensing of lipid A by the human immune system may also be critical for the onset of immune responses to Gram-negative infection, and for the subsequent successful fight against the infection. Many of the immune activating abilities of LPS can be attributed to the lipid A unit. It is a very potent stimulant of the immune system, activating cells (for example, monocytes or macrophages) at picogram per milliliter quantities. Lipid A has been found in Escherichia, Pseudomonas, Salmonella and meningococcus (PMID: 11948150; PMID: 12045108).

Isopropylbenzene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Isopropylbenzene is a component of petroleum destillates. Petroleum distillate poisoning may cause nausea, vomiting, cough, pulmonary irritation progressing to pulmonary edema, bloody sputum, and bronchial pneumonia. Petroleum distillates are also irritating to the skin. Petroleum distillates are aspiration hazards and may cause pulmonary damage, central nervous system depression, and cardiac effects such as cardiac arrhythmias. They may also affect the blood, immune system, liver, and kidney. At high amounts, central nervous system depression may also occur, with symptoms such as weakness, dizziness, slow and shallow respiration, unconsciousness, and convulsions. Gastric lavage, emesis, and the administration of activated charcoal should be avoided, as vomiting increases the risk of aspiration. Treatment is mainly symptomatic and supportive. Volatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration. Trace constituent of ginger oil (Zingiber officinale)

Lithium
Lithium (Li) is an alkali metal. First described as a mood stabilizer in 1949, it remains an efficacious treatment for bipolar disorders. Recent emerging evidence of its neuroprotective and neurogenic effects alludes to lithiums potential therapeutic use in stroke and neurodegenerative diseases. One intriguing clinical application is in the treatment of Alzheimers disease. Ongoing clinical trials are evaluating lithiums abilities to lower tau and beta-amyloid levels in cerebrospinal fluid in Alzheimers patients. Lithium reduces brain inositol levels by inhibiting the enzyme inositol monophosphatase. This suggests that inositol monophosphatase inhibition is a key mechanism of Lis therapeutic action and that design of new inositol monophosphatase inhibitors may be a practical strategy to create new compounds with Li-like therapeutic effects. Lithium reduces the severity of some behavioral complications of Alzheimers disease (AD). And there are growing indications that Li may be of benefit to the underlying pathology of AD, as well as an array of other common CNS disorders, including stroke, Parkinsons disease, and Huntingtons disease. Physiologically, it exists as an ion in the body. Despite these demonstrated and prospective therapeutic benefits, Lis mechanism of action remains elusive, and opinions differ regarding the most relevant molecular targets. Lithium inhibits several enzymes; significant among these are inositol monophosphatase (IMPase), glycogen synthase kinase-3 (GSK-3), and the proteasome. Lithium has a narrow therapeutic range, and several well characterised adverse effects limit the potential usefulness of higher doses. Acute ingestion in Li-naive patients is generally associated with only short-lived exposure to high concentrations, due to extensive distribution of Li throughout the total body water compartment. Conversely, chronic toxicity and acute-on-therapeutic ingestion are associated with prolonged exposure to higher tissue concentrations and, therefore, greater toxicity. Lithium toxicity may be life threatening, or result in persistent cognitive and neurological impairment. Therefore, enhanced Li clearance has been explored as a means of minimizing exposure to high tissue concentrations. Although haemodialysis is highly effective in removing circulating Li, serum concentrations often rebound so repeated or prolonged treatment may be required. Continuous arteriovenous haemodiafiltration and continuous venovenous haemodiafiltration increase Li clearance, albeit to a lesser extent than haemodialysis, and are more widely accessible. Lithium reduces brain inositol levels by inhibiting IMPase, suggesting that IMPases inhibition is a key mechanism of Lis therapeutic action and that design of new IMPase inhibitors may be a practical strategy to create new compounds with Li-like therapeutic effects. (PMID: 17688381, 17316163, 8110911, 17288494). Lithium is found in many foods, some of which are endive, yellow zucchini, romaine lettuce, and common bean. Lithium (Li) is an alkali metal.

Rubidium
Rubidium is a soft, silvery-white metallic element of the alkali metal group, present in traces amounts in human tissues and fluids. Rb-87, a naturally occurring isotope, is (slightly) radioactive. Rubidium is very soft and highly reactive, with properties similar to other elements in group 1, like rapid oxidation in air. Rubidium, particularly 87Rb, in the form of vapor, is one of the most commonly-used atomic species employed for laser cooling and Bose-Einstein condensation. Its desirable features for this application include the ready availability of inexpensive diode laser light at the relevant wavelength, and the moderate temperatures required to obtain substantial vapor pressures. Physiologically, it exists as an ion in the body. It has been found slightly increased in neoplastic human breast tissues obtained from patients at the time of mastectomy, compared to normal tissue. (PMID: 6488192, 15820728, 7324778, 9630429, 577330). Rubidium is a chemical element with the symbol Rb and atomic number 37. Rubidium is not known to be necessary for any living organisms. However, like caesium, rubidium ions are handled by living organisms in a manner similar to potassium ions, being actively taken up by plants and by animal cells. Rubidium, like sodium and potassium, almost always has ==+1== oxidation state when dissolved in water, including its presence in all biological systems. The human body tends to treat Rb==+== ions as if they were potassium ions, and therefore concentrates rubidium in the bodys intracellular fluid. The ions are not particularly toxic. [Wikipedia]. Rubidium is found in many foods, some of which are garden tomato, sweet orange, black walnut, and coconut.

Folinic acid
(6S)-5-formyltetrahydrofolic acid is the pharmacologically active (6S)-stereoisomer of 5-formyltetrahydrofolic acid. It has a role as an antineoplastic agent and a metabolite. It is a conjugate acid of a (6S)-5-formyltetrahydrofolate(2-). Levoleucovorin is the enantiomerically active form of Folinic Acid (also known as 5-formyl tetrahydrofolic acid or leucovorin). Commercially available leucovorin is composed of a 1:1 racemic mixture of the dextrorotary and levorotary isomers, while levoleucovorin contains only the pharmacologically active levo-isomer. In vitro, the levo-isomer has been shown to be rapidly converted to the biologically available methyl-tetrahydrofolate form while the dextro form is slowly excreted by the kidneys. Despite this difference in activity, the two commercially available forms have been shown to be pharmacokinetically identical and may be used interchangeably with limited differences in efficacy or side effects (Kovoor et al, 2009). As folate analogs, levoleucovorin and leucovorin are both used to counteract the toxic effects of folic acid antagonists, such as methotrexate, which act by inhibiting the enzyme dihydrofolate reductase (DHFR). They are indicated for use as rescue therapy following use of high-dose methotrexate in the treatment of osteosarcoma or for diminishing the toxicity associated with inadvertent overdosage of folic acid antagonists. Levoleucovorin, as the product Fusilev (FDA), has an additional indication for use in combination chemotherapy with 5-fluorouracil in the palliative treatment of patients with advanced metastatic colorectal cancer. Folic acid is an essential B vitamin required by the body for the synthesis of purines, pyrimidines, and methionine before incorporation into DNA or protein. However, in order to function in this role, it must first be reduced by the enzyme dihydrofolate reductase (DHFR) into the cofactors dihydrofolate (DHF) and tetrahydrofolate (THF). This important pathway, which is required for de novo synthesis of nucleic acids and amino acids, is disrupted when high-dose methotrexate is used for cancer therapy. As methotrexate functions as a DHFR inhibitor to prevent DNA synthesis in rapidly dividing cells, it also prevents the formation of DHF and THF. This results in a deficiency of coenzymes and a resultant buildup of toxic substances that are responsible for numerous adverse side effects of methotrexate therapy. As levoleucovorin and leucovorin are analogs of tetrahydrofolate (THF), they are able to bypass DHFR reduction and act as a cellular replacement for the co-factor THF, thereby preventing these toxic side effects. Levoleucovorin is a Folate Analog. Levoleucovorin is a natural product found in Homo sapiens with data available. Levoleucovorin is the active l-isomer of the racemic mixture of the 5-formyl derivative of tetrahydrofolic acid. Metabolically active, l-leucovorin, also known levoleucovorin, does not require bioactivation by dihydrofolate reductase, an enzyme inhibited by folic acid antagonists. This agent may enhance the effects of fluoropyrimidines by stabilizing their binding to the enzyme thymidylate synthase. (NCI04) 5-Formyltetrahydrofolic acid is a metabolite found in or produced by Saccharomyces cerevisiae. A folate analog consisting of the pharmacologically active isomer of LEUCOVORIN. See also: Levoleucovorin Calcium (active moiety of); Levoleucovorin disodium (active moiety of). Folinic acid (CAS: 58-05-9), also known as leucovorin, is a medication used to decrease the toxic effects of methotrexate (a chemotherapy agent and immune system suppressant) and pyrimethamine (Wikipedia). Folinic acid is the active metabolite of folic acid. Leucovorin is used principally as its calcium salt as an antidote to folic acid antagonists which block the conversion of folic acid to folinic acid.

3alpha,7alpha,12beta-Trihydroxy-5beta-cholanoic acid
3alpha,7alpha,12beta-Trihydroxy-5beta-cholanoic acid, also known as lagocholic acid, is a bile acid. Bile acids with beta-hydroxyl and carbonyl groups at the C-3,7, and/or 12 positions are bile acids usually found in the urine of healthy humans (PMID: 8743575). Bile acids are steroid acids found predominantly in the bile of mammals. The distinction between different bile acids is minute, depending only on the presence or absence of hydroxyl groups on positions 3, 7, and 12. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. Bile acids have potent toxic properties (e.g. membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues (PMID: 11316487, 16037564, 12576301, 11907135).

Flumequine
Ciprofloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It functions by inhibiting DNA gyrase, a type II topoisomerase, and topoisomerase IV, enzymes necessary to separate bacterial DNA, thereby inhibiting cell division. Flumequine is a 9-fluoro-6,7-dihydro-5-methyl-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid. The molecular formula is C14H12FNO3 It is a white powder, odorless, flavorless, insoluble in water but soluble in organic solvent. Flumequine is a synthetic chemotherapeutic antibiotic of the fluoroquinolone drug class used to treat bacterial infections. It is a first-generation fluoroquinolone antibacterial that has been removed from clinical use and is no longer being marketed. It kills bacteria by interfering with the enzymes that cause DNA to unwind and duplicate. Flumequine was used in veterinarian medicine for the treatment of enteric infections (all infections of the intestinal tract), as well as to treat cattle, swine, chickens, and fish, but only in a limited number of countries. It was occasionally used in France (and a few other European Countries) to treat urinary tract infections under the trade name Apurone. However this was a limited indication because only minimal serum levels were achieved. The first quinolone used was nalidixic acid (was marketed in many countries as Negram) followed by the fluoroquinolone flumequine. The first-generation fluoroquinolone agents, such as flumequine, had poor distribution into the body tissues and limited activity. As such they were used mainly for treatment of urinary tract infections. Flumequine (benzo quinolizine) was first patented in 1973, (German Patent) by Rikker Labs. Flumequine is a known antimicrobial compound described and claimed in U.S. Pat. No. 3,896,131 (Example 3), July 22, 1975. Flumequine is the first quinolone compound with a fluorine atom at the C6-position of the related quinolone basic molecular structure. Even though this was the first fluoroquinolone, it is oftentimes overlooked when classifying the drugs within this class by generations and excluded from such a list. There continues to be considerable debate as to whether or not this DNA damage is to be considered one of the mechanisms of action concerning the severe adverse reactions experienced by some patients following fluoroquinolone therapy.

(3R,3'R,6'R,9-cis)-beta,epsilon-Carotene-3,3'-diol
(3R,3R,6R,9-cis)-beta,epsilon-Carotene-3,3-diol is a carotenoid found in human fluids such as serum and breast milk (PMID: 9164160). Carotenoids are isoprenoid molecules that are widespread in nature and are typically seen as pigments in fruits, flowers, birds and crustacea. Animals are unable to synthesise carotenoids de novo, and rely upon the diet as a source of these compounds. Over recent years there has been considerable interest in dietary carotenoids with respect to their potential in alleviating age-related diseases in humans. This attention has been mirrored by significant advances in cloning most of the carotenoid genes and in the genetic manipulation of crop plants with the intention of increasing levels in the diet. Studies have shown an inverse relationship between the consumption of certain fruits and vegetables and the risk of epithelial cancer. Since carotenoids are among the micronutrients found in cancer preventive foods, detailed qualitative and quantitative determination of these compounds, particularly in fruits and vegetables and in human plasma, have recently become increasingly important (PMID: 1416048, 15003396).

Thromboxane A2
Thromboxane A2 is an unstable intermediate between the prostaglandin endoperoxides and thromboxane B2. The compound has a bicyclic oxaneoxetane structure. It is a potent inducer of platelet aggregation and causes vasoconstriction. It is the principal component of rabbit aorta contracting substance (RCS).Thromboxanes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways.
Leucinic acid
Leucinic acid, also known as leucic acid, 2-hydroxyisocaproic acid or 2-hydroxy-4-methylvaleric acid, belongs to the class of organic compounds known as hydroxy fatty acids. These are fatty acids in which the chain bears a hydroxyl group. Leucinic acid is a valeric acid derivative having a hydroxy substituent at the 2-position and a methyl substituent at the 4-position. It is an alpha-hydroxy analogue of leucine and a metabolite of the branched-chain amino acid leucine. Leucinic acid is found in all organisms ranging from bacteria to plants to animals. Leucinic acid has been found in a patient with dihydrolipoyl dehydrogenase (DLD) deficiency (PMID: 6688766). DLD deficiency is caused by mutations in the DLD gene and is inherited in an autosomal recessive manner. A common feature of dihydrolipoamide dehydrogenase deficiency is a potentially life-threatening buildup of lactic acid in tissues (lactic acidosis), which can cause nausea, vomiting, severe breathing problems, and an abnormal heartbeat. Neurological problems are also common in this condition; the first symptoms in affected infants are often decreased muscle tone (hypotonia) and extreme tiredness (lethargy). As the problems worsen, affected infants can have difficulty feeding, decreased alertness, and seizures. Liver problems can also occur in dihydrolipoamide dehydrogenase deficiency, ranging from an enlarged liver (hepatomegaly) to life-threatening liver failure. In some affected people, liver disease, which can begin anytime from infancy to adulthood, is the primary symptom. Leucinic acid is also present in the urine of patients with short bowel syndrome (PMID: 4018104) Leucinic acid has been isolated from amniotic fluid (PMID: 6467607), and have been found in a patient with dihydrolipoyl dehydrogenase deficiency (PMID 6688766).
Indoleacrylic acid
Indoleacrylic acid (CAS: 1204-06-4), also known as indoleacrylate, IA, and IAcrA, is a member of the class of compounds known as indoles. Indoles are compounds containing an indole moiety, which consists of pyrrole ring fused to benzene to form 2,3-benzopyrrole. Indoleacrylic acid is practically insoluble (in water) and a weak acidic compound (based on its pKa). Within the cell, indoleacrylic acid is primarily located in the membrane (predicted from logP). Indoleacrylic acid is best known as a plant growth hormone (a natural auxin), whereas its biological role in animals is still unknown. A two-stage production of this compound is likely: intestinal microorganisms catabolize tryptophan to indole derivatives which are then absorbed and converted into indoleacrylic acid and its glycine conjugate, indolylacryloylglycine (IAcrGly). Indolylacryloylglycine excretion in urine is especially pronounced in some myopathies, namely in boys with Duchenne muscular dystrophy (PMID: 10707769). It has been recently found that indoleacrylic acid promotes intestinal epithelial barrier function and mitigates inflammatory responses. Stimulating indoleacrylic acid production could promote anti-inflammatory responses and have therapeutic benefits (PMID: 28704649). Urinary Indole-3-acrylate is produced by Clostridium sporogenes (PMID: 29168502). Indoleacrylic acid is also a metabolite of Peptostreptococcus (PMID: 28704649, 29168502). trans-3-Indoleacrylic acid is an endogenous metabolite.

5,6,7,8-Tetrahydrofolic acid
Tetrahydrofolate is a soluble coenzyme (vitamin B9) that is synthesized de novo by plants and microorganisms, and absorbed from the diet by animals. It is composed of three distinct parts: a pterin ring, a p-ABA (p-aminobenzoic acid) and a polyglutamate chain with a number of residues varying between 1 and 8. Only the tetra-reduced form of the molecule serves as a coenzyme for C1 transfer reactions. In biological systems, the C1-units exist under various oxidation states and the different tetrahydrofolate derivatives constitute a family of related molecules named indistinctly under the generic term folate.

2-Aminoadipic acid
Aminoadipic acid, also known as a-aminoadipate or Aad, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Aminoadipic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Aminoadipic acid exists in all eukaryotes, ranging from yeast to humans. Within humans, aminoadipic acid participates in a number of enzymatic reactions. In particular, aminoadipic acid can be biosynthesized from allysine; which is mediated by the enzyme Alpha-aminoadipic semialdehyde dehydrogenase. In addition, aminoadipic acid and oxoglutaric acid can be converted into oxoadipic acid and L-glutamic acid; which is catalyzed by the enzyme kynurenine/alpha-aminoadipate aminotransferase, mitochondrial. In humans, aminoadipic acid is involved in the metabolic disorder called 2-aminoadipic 2-oxoadipic aciduria. Outside of the human body, Aminoadipic acid is found, on average, in the highest concentration within a few different foods, such as wheats, milk (cow), and ryes and in a lower concentration in dills, garden onions, and white cabbages. Aminoadipic acid has also been detected, but not quantified in, several different foods, such as barley, cow milks, cow milks, cow milks, and cow milks. This could make aminoadipic acid a potential biomarker for the consumption of these foods. Aminoadipic acid is a potentially toxic compound. Aminoadipic acid, with regard to humans, has been found to be associated with several diseases such as alpha-aminoadipic and alpha-ketoadipic aciduria, colorectal cancer, metastatic melanoma, and eosinophilic esophagitis; aminoadipic acid has also been linked to the inborn metabolic disorder 2-ketoadipic acidemia. A metabolite in the principal biochemical pathway of lysine. It antagonizes neuroexcitatory activity modulated by the glutamate receptor, N-methyl-D-aspartate; (NMDA).

β-Carotene
The novel carbohydrate-derived b-carboline, 1-pentahydroxypentyl-1,2,3,4-tetrahydro-b-carboline-3-carboxylic acid, was identified in fruit- and vegetable-derived products such as juices, jams, and tomato sauces. This compound occurred as two diastereoisomers, a cis isomer (the major compound) and a trans isomer, ranging from undetectable amounts to 6.5 ug/g. Grape, tomato, pineapple, and tropical juices exhibited the highest amount of this alkaloid (up to 3.8 mg/L), whereas apple, banana, and peach juices showed very low or nondetectable levels. This tetrahydro-b-carboline was also found in jams (up to 0.45 ug/g), and a relative high amount was present in tomato concentrate (6.5 ug/g) and sauce (up to 1.8 ug/g). This b-carboline occurred in fruit-derived products as a glycoconjugate from a chemical condensation of d-glucose and l-tryptophan that is highly favored at low pH values and high temperature. Production, processing treatments, and storage of fruit juices and jams can then release this b-carboline. Fruit-derived products and other foods containing this compound might be an exogenous dietary source of this glucose-derived tetrahydro-b-carboline.(PMID: 12137498) [HMDB] Window width to select the precursor ion was 3 Da.; CONE_VOLTAGE is 20 V.; This record was created by the financial support of MEXT/JSPS KAKENHI Grant Number 19HP8024 to the Mass Spectrometry Society of Japan.

Zeaxanthin
Meso-zeaxanthin (3R,3´S-zeaxanthin) is a xanthophyll carotenoid, as it contains oxygen and hydrocarbons, and is one of the three stereoisomers of zeaxanthin. Of the three stereoisomers, meso-zeaxanthin is the second most abundant in nature after 3R,3´R-zeaxanthin, which is produced by plants and algae. To date, meso-zeaxanthin has been identified in specific tissues of marine organisms and in the macula lutea, also known as the "yellow spot", of the human retina . Meso-zeaxanthin is a member of the class of compounds known as xanthophylls. Xanthophylls are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone. Meso-zeaxanthin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Meso-zeaxanthin can be found in channel catfish, crustaceans, and fishes, which makes meso-zeaxanthin a potential biomarker for the consumption of these food products.

cholate
Cholic acid, also known as 3a,7a,12a-trihydroxy-5b-cholanate or cholate, belongs to trihydroxy bile acids, alcohols and derivatives class of compounds. Those are prenol lipids structurally characterized by a bile acid or alcohol which bears three hydroxyl groups. Thus, cholic acid is considered to be a bile acid lipid molecule. Cholic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Cholic acid can be found in a number of food items such as cocoa bean, walnut, garden rhubarb, and carob, which makes cholic acid a potential biomarker for the consumption of these food products. Cholic acid can be found primarily in bile, blood, feces, and urine, as well as throughout all human tissues. Cholic acid exists in all living organisms, ranging from bacteria to humans. In humans, cholic acid is involved in few metabolic pathways, which include bile acid biosynthesis, cerebrotendinous xanthomatosis (CTX), congenital bile acid synthesis defect type II, and congenital bile acid synthesis defect type III. Cholic acid is also involved in few metabolic disorders, which include 27-hydroxylase deficiency, familial hypercholanemia (FHCA), and zellweger syndrome. Moreover, cholic acid is found to be associated with biliary atresia, cirrhosis, cystic fibrosis, and primary biliary cirrhosis. Cholic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound.

Cyanidin 3-glucoside
Cyanidin 3-glucoside, also known as chrysanthenin or cyanidin 3-glucoside chloride (CAS: 7084-24-4), belongs to the class of organic compounds known as pyranones and derivatives. Pyranones and derivatives are compounds containing a pyran ring which bears a ketone. Cyanidin 3-glucoside is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, cyanidin 3-glucoside is found, on average, in the highest concentration within a few different foods, such as black elderberries, rubus (blackberry, raspberry), and bilberries and in a lower concentration in redcurrants, strawberries, and sweet oranges. Cyanidin 3-glucoside has also been detected, but not quantified in, several different foods, such as common pea, peaches, Tartary buckwheats, soft-necked garlic, and fats and oils. This could make cyanidin 3-glucoside a potential biomarker for the consumption of these foods. Cyanidin (and its glycosides) is the most commonly occurring of the anthocyanins, a widespread group of pigments responsible for the red-blue colour of many fruits and vegetables (PMID: 14711454). BioTransformer predicts that cyanidin 3-glucoside is a product of cyanidin 3-sophoroside metabolism via a glycoside-hydrolysis reaction occurring in human gut microbiota and catalyzed by the EC.3.2.1.X enzyme (PMID: 30612223). Found in many plants and fruits, e.g. cherries, olives and grapes
