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to thallium-201 in myocardial perfusion scintigraphy, though it is rarely used in this indication, having largely been replaced by [dipyridamole] and [regadenson].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

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

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. Tyrosine is an essential amino acid 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.

linolenate(18:3)
alpha-Linolenic acid (ALA) is a polyunsaturated fatty acid (PUFA). It is a member of the group of essential fatty acids called omega-3 fatty acids. alpha-Linolenic acid, in particular, is not synthesized by mammals and therefore is an essential dietary requirement for all mammals. Certain nuts (English walnuts) and vegetable oils (canola, soybean, flaxseed/linseed, olive) are particularly rich in alpha-linolenic acid. Omega-3 fatty acids get their name based on the location of one of their first double bond. In all omega-3 fatty acids, the first double bond is located between the third and fourth carbon atom counting from the methyl end of the fatty acid (n-3). Although humans and other mammals can synthesize saturated and some monounsaturated fatty acids from carbon groups in carbohydrates and proteins, they lack the enzymes necessary to insert a cis double bond at the n-6 or the n-3 position of a fatty acid. Omega-3 fatty acids like alpha-linolenic acid are important structural components of cell membranes. When incorporated into phospholipids, they affect cell membrane properties such as fluidity, flexibility, permeability, and the activity of membrane-bound enzymes. Omega-3 fatty acids can modulate the expression of a number of genes, including those involved with fatty acid metabolism and inflammation. alpha-Linolenic acid and other omega-3 fatty acids may regulate gene expression by interacting with specific transcription factors, including peroxisome proliferator-activated receptors (PPARs) and liver X receptors (LXRs). alpha-Linolenic acid is found to be associated with isovaleric acidemia, which is an inborn error of metabolism. α-Linolenic acid can be obtained by humans only through their diets. Humans lack the desaturase enzymes required for processing stearic acid into A-linoleic acid or other unsaturated fatty acids. Dietary α-linolenic acid is metabolized to stearidonic acid, a precursor to a collection of polyunsaturated 20-, 22-, 24-, etc fatty acids (eicosatetraenoic acid, eicosapentaenoic acid, docosapentaenoic acid, tetracosapentaenoic acid, 6,9,12,15,18,21-tetracosahexaenoic acid, docosahexaenoic acid).[12] Because the efficacy of n−3 long-chain polyunsaturated fatty acid (LC-PUFA) synthesis decreases down the cascade of α-linolenic acid conversion, DHA synthesis from α-linolenic acid is even more restricted than that of EPA.[13] Conversion of ALA to DHA is higher in women than in men.[14] α-Linolenic acid, also known as alpha-linolenic acid (ALA) (from Greek alpha meaning "first" and linon meaning flax), is an n−3, or omega-3, essential fatty acid. ALA is found in many seeds and oils, including flaxseed, walnuts, chia, hemp, and many common vegetable oils. In terms of its structure, it is named all-cis-9,12,15-octadecatrienoic acid.[2] In physiological literature, it is listed by its lipid number, 18:3 (n−3). It is a carboxylic acid with an 18-carbon chain and three cis double bonds. The first double bond is located at the third carbon from the methyl end of the fatty acid chain, known as the n end. Thus, α-linolenic acid is a polyunsaturated n−3 (omega-3) fatty acid. It is a regioisomer of gamma-linolenic acid (GLA), an 18:3 (n−6) fatty acid (i.e., a polyunsaturated omega-6 fatty acid with three double bonds). Alpha-linolenic acid is a linolenic acid with cis-double bonds at positions 9, 12 and 15. Shown to have an antithrombotic effect. It has a role as a micronutrient, a nutraceutical and a mouse metabolite. It is an omega-3 fatty acid and a linolenic acid. It is a conjugate acid of an alpha-linolenate and a (9Z,12Z,15Z)-octadeca-9,12,15-trienoate. Alpha-linolenic acid (ALA) is a polyunsaturated omega-3 fatty acid. It is a component of many common vegetable oils and is important to human nutrition. alpha-Linolenic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Linolenic Acid is a natural product found in Prunus mume, Dipteryx lacunifera, and other organisms with data available. Linolenic Acid is an essential fatty acid belonging to the omega-3 fatty acids group. It is highly concentrated in certain plant oils and has been reported to inhibit the synthesis of prostaglandin resulting in reduced inflammation and prevention of certain chronic diseases. Alpha-linolenic acid (ALA) is a polyunsaturated omega-3 fatty acid. It is a component of many common vegetable oils and is important to human nutrition. A fatty acid that is found in plants and involved in the formation of prostaglandins. Seed oils are the richest sources of α-linolenic acid, notably those of hempseed, chia, perilla, flaxseed (linseed oil), rapeseed (canola), and soybeans. α-Linolenic acid is also obtained from the thylakoid membranes in the leaves of Pisum sativum (pea leaves).[3] Plant chloroplasts consisting of more than 95 percent of photosynthetic thylakoid membranes are highly fluid due to the large abundance of ALA, evident as sharp resonances in high-resolution carbon-13 NMR spectra.[4] Some studies state that ALA remains stable during processing and cooking.[5] However, other studies state that ALA might not be suitable for baking as it will polymerize with itself, a feature exploited in paint with transition metal catalysts. Some ALA may also oxidize at baking temperatures. Gamma-linolenic acid (γ-Linolenic acid) is an omega-6 (n-6), 18 carbon (18C-) polyunsaturated fatty acid (PUFA) extracted from Perilla frutescens. Gamma-linolenic acid supplements could restore needed PUFAs and mitigate the disease[1]. Gamma-linolenic acid (γ-Linolenic acid) is an omega-6 (n-6), 18 carbon (18C-) polyunsaturated fatty acid (PUFA) extracted from Perilla frutescens. Gamma-linolenic acid supplements could restore needed PUFAs and mitigate the disease[1]. α-Linolenic acid, isolated from Perilla frutescens, is an essential fatty acid that cannot be synthesized by humans. α-Linolenic acid can affect the process of thrombotic through the modulation of PI3K/Akt signaling. α-Linolenic acid possess the anti-arrhythmic properties and is related to cardiovascular disease and cancer[1]. α-Linolenic acid, isolated from Perilla frutescens, is an essential fatty acid that cannot be synthesized by humans. α-Linolenic acid can affect the process of thrombotic through the modulation of PI3K/Akt signaling. α-Linolenic acid possess the anti-arrhythmic properties and is related to cardiovascular disease and cancer[1]. α-Linolenic acid, isolated from Perilla frutescens, is an essential fatty acid that cannot be synthesized by humans. α-Linolenic acid can affect the process of thrombotic through the modulation of PI3K/Akt signaling. α-Linolenic acid possess the anti-arrhythmic properties and is related to cardiovascular disease and cancer[1].
Uridine
Uridine, also known as beta-uridine or 1-beta-D-ribofuranosylpyrimidine-2,4(1H,3H)-dione, is a member of the class of compounds known as pyrimidine nucleosides. Pyrimidine nucleosides are compounds comprising a pyrimidine base attached to a ribosyl or deoxyribosyl moiety. More specifically, uridine is a nucleoside consisting of uracil and D-ribose and a component of RNA. Uridine is soluble (in water) and a very weakly acidic compound (based on its pKa). Uridine can be synthesized from uracil. It is one of the five standard nucleosides which make up nucleic acids, the others being adenosine, thymidine, cytidine and guanosine. The five nucleosides are commonly abbreviated to their one-letter codes U, A, T, C and G respectively. Uridine is also a parent compound for other transformation products, including but not limited to, nikkomycin Z, 3-(enolpyruvyl)uridine 5-monophosphate, and 5-aminomethyl-2-thiouridine. Uridine can be found in most biofluids, including urine, breast milk, cerebrospinal fluid (CSF), and blood. Within the cell, uridine is primarily located in the mitochondria, in the nucleus and the lysosome. It can also be found in the extracellular space. As an essential nucleoside, uridine exists in all living species, ranging from bacteria to humans. In humans, uridine is involved in several metabolic disorders, some of which include dhydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and beta-ureidopropionase deficiency. Moreover, uridine is found to be associated with Lesch-Nyhan syndrome, which is an inborn error of metabolism. Uridine is a nucleoside consisting of uracil and D-ribose and a component of RNA. Uridine plays a role in the glycolysis pathway of galactose. In humans there is no catabolic process to metabolize galactose. Therefore, galactose is converted to glucose and metabolized via the normal glucose metabolism pathways. More specifically, consumed galactose is converted into galactose 1-phosphate (Gal-1-P). This molecule is a substrate for the enzyme galactose-1-phosphate uridyl transferase which transfers a UDP molecule to the galactose molecule. The end result is UDP-galactose and glucose-1-phosphate. This process is continued to allow the proper glycolysis of galactose. Uridine is found in many foods (anything containing RNA) but is destroyed in the liver and gastrointestinal tract, and so no food, when consumed, has ever been reliably shown to elevate blood uridine levels. On the other hand, consumption of RNA-rich foods may lead to high levels of purines (adenine and guanosine) in blood. High levels of purines are known to increase uric acid production and may aggravate or lead to conditions such as gout. Uridine is a ribonucleoside composed of a molecule of uracil attached to a ribofuranose moiety via a beta-N(1)-glycosidic bond. It has a role as a human metabolite, a fundamental metabolite and a drug metabolite. It is functionally related to a uracil. Uridine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Uridine is a Pyrimidine Analog. The chemical classification of uridine is Pyrimidines, and Analogs/Derivatives. Uridine is a natural product found in Ulva australis, Synechocystis, and other organisms with data available. Uridine is a nucleoside consisting of uracil and D-ribose and a component of RNA. Uridine has been studied as a rescue agent to reduce the toxicities associated with 5-fluorouracil (5-FU), thereby allowing the administration of higher doses of 5-FU in chemotherapy regimens.

4-Hydroxybenzoic acid
4-Hydroxybenzoic acid, also known as p-hydroxybenzoate or 4-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. 4-Hydroxybenzoic acid is a white crystalline solid that is slightly soluble in water and chloroform but more soluble in polar organic solvents such as alcohols and acetone. It is a nutty and phenolic tasting compound. 4-Hydroxybenzoic acid exists in all living species, ranging from bacteria to plants to humans. 4-Hydroxybenzoic acid can be found naturally in coconut. It is one of the main catechins metabolites found in humans after consumption of green tea infusions. It is also found in wine, in vanilla, in Açaí oil, obtained from the fruit of the açaí palm (Euterpe oleracea), at relatively high concetrations (892±52 mg/kg). It is also found in cloudy olive oil and in the edible mushroom Russula virescens. It has been detected in red huckleberries, rabbiteye blueberries, and corianders and in a lower concentration in olives, red raspberries, and almonds. In humans, 4-hydroxybenzoic acid is involved in ubiquinone biosynthesis. In particular, the enzyme 4-hydroxybenzoate polyprenyltransferase uses a polyprenyl diphosphate and 4-hydroxybenzoate to produce diphosphate and 4-hydroxy-3-polyprenylbenzoate. This enzyme participates in ubiquinone biosynthesis. 4-Hydroxybenzoic acid can be biosynthesized by the enzyme Chorismate lyase. Chorismate lyase is an enzyme that transforms chorismate into 4-hydroxybenzoate and pyruvate. This enzyme catalyses the first step in ubiquinone biosynthesis in Escherichia coli and other Gram-negative bacteria. 4-Hydroxybenzoate is an intermediate in many enzyme-mediated reactions in microbes. For instance, the enzyme 4-hydroxybenzaldehyde dehydrogenase uses 4-hydroxybenzaldehyde, NAD+ and H2O to produce 4-hydroxybenzoate, NADH and H+. This enzyme participates in toluene and xylene degradation in bacteria such as Pseudomonas mendocina. 4-hydroxybenzaldehyde dehydrogenase is also found in carrots. The enzyme 4-hydroxybenzoate 1-hydroxylase transforms 4-hydroxybenzoate, NAD(P)H, 2 H+ and O2 into hydroquinone, NAD(P)+, H2O and CO2. This enzyme participates in 2,4-dichlorobenzoate degradation and is found in Candida parapsilosis. The enzyme 4-hydroxybenzoate 3-monooxygenase transforms 4-hydroxybenzoate, NADPH, H+ and O2 into protocatechuate, NADP+ and H2O. This enzyme participates in benzoate degradation via hydroxylation and 2,4-dichlorobenzoate degradation and is found in Pseudomonas putida and Pseudomonas fluorescens. 4-Hydroxybenzoic acid is a popular antioxidant in part because of its low toxicity. 4-Hydroxybenzoic acid has estrogenic activity both in vitro and in vivo (PMID 9417843).
Isolated from many plants, free and combined. Alkyl esters of 4-hydroxybenzoic acid (see below) are used as food and cosmetic preservatives, mainly in their Na salt form, which makes them more water soluble. They are active at low concentrations and more pH-independent than the commonly used Benzoic acid
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. Slightly bitter taste. pH (1\\\\\\% aqueous solution) 5.4 to 6. (NTP, 1992) L-phenylalanine is the L-enantiomer of phenylalanine. It has a role as a nutraceutical, a micronutrient, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite, an algal metabolite, a mouse metabolite, a human xenobiotic metabolite and an EC 3.1.3.1 (alkaline phosphatase) inhibitor. 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). The psychotropic drugs (mescaline, morphine, codeine, and papaverine) also have phenylalanine as a constituent. Phenylalanine is a precursor of the neurotransmitters called catecholamines, which are adrenalin-like substances. 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 high protein foods, such as meat, cottage cheese and wheat germ. A new dietary source of phenylalanine is artificial sweeteners containing aspartame. 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.

Palmitic acid
Palmitic acid, also known as palmitate or hexadecanoic 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, palmitic acid is considered to be a fatty acid lipid molecule. Palmitic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Palmitic acid can be found in a number of food items such as sacred lotus, spinach, shallot, and corn salad, which makes palmitic acid a potential biomarker for the consumption of these food products. Palmitic acid can be found primarily in most biofluids, including feces, sweat, cerebrospinal fluid (CSF), and urine, as well as throughout most human tissues. Palmitic acid exists in all living species, ranging from bacteria to humans. In humans, palmitic acid is involved in several metabolic pathways, some of which include alendronate action pathway, rosuvastatin action pathway, simvastatin action pathway, and cerivastatin action pathway. Palmitic acid is also involved in several metabolic disorders, some of which include hypercholesterolemia, familial lipoprotein lipase deficiency, ethylmalonic encephalopathy, and carnitine palmitoyl transferase deficiency (I). Moreover, palmitic acid is found to be associated with schizophrenia. Palmitic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Palmitic acid, or hexadecanoic acid in IUPAC nomenclature, is the most common saturated fatty acid found in animals, plants and microorganisms. Its chemical formula is CH3(CH2)14COOH, and its C:D is 16:0. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Palmitic acid can also be found in meats, cheeses, butter, and dairy products. Palmitate is the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4) . Palmitic acid is the first fatty acid produced during lipogenesis (fatty acid synthesis) and from which longer fatty acids can be produced. Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC) which is responsible for converting acetyl-ACP to malonyl-ACP on the growing acyl chain, thus preventing further palmitate generation (DrugBank). Palmitic acid, or hexadecanoic acid, is one of the most common saturated fatty acids found in animals, plants, and microorganisms. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Excess carbohydrates in the body are converted to palmitic acid. Palmitic acid is the first fatty acid produced during fatty acid synthesis and is the precursor to longer fatty acids. As a consequence, palmitic acid is a major body component of animals. In humans, one analysis found it to make up 21–30\\\% (molar) of human depot fat (PMID: 13756126), and it is a major, but highly variable, lipid component of human breast milk (PMID: 352132). Palmitic acid is used to produce soaps, cosmetics, and industrial mould release agents. These applications use sodium palmitate, which is commonly obtained by saponification of palm oil. To this end, palm oil, rendered from palm tree (species Elaeis guineensis), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate. Aluminium salts of palmitic acid and naphthenic acid were combined during World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid (Wikipedia). Palmitic acid is also used in the determination of water hardness and is a surfactant of Levovist, an intravenous ultrasonic contrast agent. Hexadecanoic acid is a straight-chain, sixteen-carbon, saturated long-chain fatty acid. It has a role as an EC 1.1.1.189 (prostaglandin-E2 9-reductase) inhibitor, a plant metabolite, a Daphnia magna metabolite and an algal metabolite. It is a long-chain fatty acid and a straight-chain saturated fatty acid. It is a conjugate acid of a hexadecanoate.

Stigmasterol
Stigmasterol is a phytosterol, meaning it is steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention. Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15\\%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. Stigmasterol is found to be associated with phytosterolemia, which is an inborn error of metabolism. Stigmasterol is a 3beta-sterol that consists of 3beta-hydroxystigmastane having double bonds at the 5,6- and 22,23-positions. It has a role as a plant metabolite. It is a 3beta-sterol, a stigmastane sterol, a 3beta-hydroxy-Delta(5)-steroid and a member of phytosterols. It derives from a hydride of a stigmastane. Stigmasterol is a natural product found in Ficus auriculata, Xylopia aromatica, and other organisms with data available. Stigmasterol is a steroid derivative characterized by the hydroxyl group in position C-3 of the steroid skeleton, and unsaturated bonds in position 5-6 of the B ring, and position 22-23 in the alkyl substituent. Stigmasterol is found in the fats and oils of soybean, calabar bean and rape seed, as well as several other vegetables, legumes, nuts, seeds, and unpasteurized milk. See also: Comfrey Root (part of); Saw Palmetto (part of); Plantago ovata seed (part of). Stigmasterol is an unsaturated plant sterol occurring in the plant fats or oils of soybean, calabar bean, and rape seed, and in a number of medicinal herbs, including the Chinese herbs Ophiopogon japonicus (Mai men dong) and American Ginseng.

Constituent of Artocarpus integrifolia fruits and Solanum tuberosum (potato)
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.

L-Alanine
Alanine (Ala), also known as L-alanine 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. Alanine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar amino acid. In humans, alanine is a non-essential amino acid that can be easily made in the body from either the conversion of pyruvate or the breakdown of the dipeptides carnosine and anserine. Alanine can be also synthesized from branched chain amino acids such as valine, leucine, and isoleucine. Alanine is produced by reductive amination of pyruvate through a two-step process. In the first step, alpha-ketoglutarate, ammonia and NADH are converted by the enzyme known glutamate dehydrogenase to glutamate, NAD+ and water. In the second step, the amino group of the newly-formed glutamate is transferred to pyruvate by an aminotransferase enzyme, regenerating the alpha-ketoglutarate, and converting the pyruvate to alanine. The net result is that pyruvate and ammonia are converted to alanine. In mammals, alanine plays a key role in glucose–alanine cycle between tissues and liver. In muscle and other tissues that degrade amino acids for fuel, amino groups are collected in the form of glutamate by transamination. Glutamate can then transfer its amino group to pyruvate, a product of muscle glycolysis, through the action of alanine aminotransferase, forming alanine and alpha-ketoglutarate. The alanine enters the bloodstream and is transported to the liver. The alanine aminotransferase reaction takes place in reverse in the liver, where the regenerated pyruvate is used in gluconeogenesis, forming glucose which returns to the muscles through the circulation system. Alanine is highly concentrated in muscle and is one of the most important amino acids released by muscle, functioning as a major energy source. Plasma alanine is often decreased when the BCAA (branched-chain amino acids) are deficient. This finding may relate to muscle metabolism. Alanine is highly concentrated in meat products and other high-protein foods like wheat germ and cottage cheese. Alanine is an important participant as well as a regulator of glucose metabolism. Alanine levels parallel blood sugar levels in both diabetes and hypoglycemia, and alanine is reduced in both severe hypoglycemia and the ketosis of diabetes. Alanine is an important amino acid for lymphocyte reproduction and immunity. Alanine therapy has helped dissolve kidney stones in experimental animals. Normal alanine metabolism, like that of other amino acids, is highly dependent upon enzymes that contain vitamin B6. Alanine, like GABA, taurine, and glycine, is an inhibitory neurotransmitter in the brain (http://www.dcnutrition.com/AminoAcids/). L-Alanine. CAS Common Chemistry.

4-Bromophenol
4-Bromophenol, also known as P-Bromohydroxybenzene, is classified as a member of the P-bromophenols. P-bromophenols are bromophenols carrying a iodine at the C4 position of the benzene ring. 4-Bromophenol is considered to be slightly soluble (in water) and acidic
Stearidonic acid
Steridonic acid, also known as (6z,9z,12z,15z)-octadecatetraenoic acid or stearidonate, belongs to lineolic acids and derivatives class of compounds. Those are derivatives of lineolic acid. Lineolic acid is a polyunsaturated omega-6 18 carbon long fatty acid, with two CC double bonds at the 9- and 12-positions. Thus, steridonic acid is considered to be a fatty acid lipid molecule. Steridonic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Steridonic acid can be found in borage, which makes steridonic acid a potential biomarker for the consumption of this food product. Steridonic acid can be found primarily in blood and feces. In humans, steridonic acid is involved in the alpha linolenic acid and linoleic acid metabolism. Stearidonic acid is found in dietary plant oils which are metabolized to longer-chain, more unsaturated (n-3) PUFA. These oils appear to possess hypotriglyceridemic properties typically associated with fish oils.(PMID: 15173404). Stearidonic acid may be used as a precursor to increase the EPA content of human lipids and that combinations of gamma-linolenic acid and stearidonic acid eicosapentaenoic acid can be used to manipulate the fatty acid compositions of lipid pools in subtle ways. Such effects may offer new strategies for manipulation of cell composition in order to influence cellular responses and functions in desirable ways. (PMID: 15120716).
Cholesterol
Cholesterol is a sterol (a combination steroid and alcohol) and a lipid found in the cell membranes of all body tissues and transported in the blood plasma of all animals. The name originates from the Greek chole- (bile) and stereos (solid), and the chemical suffix -ol for an alcohol. This is because researchers first identified cholesterol in solid form in gallstones in 1784. In the body, cholesterol can exist in either the free form or as an ester with a single fatty acid (of 10-20 carbons in length) covalently attached to the hydroxyl group at position 3 of the cholesterol ring. Due to the mechanism of synthesis, plasma cholesterol esters tend to contain relatively high proportions of polyunsaturated fatty acids. Most of the cholesterol consumed as a dietary lipid exists as cholesterol esters. Cholesterol esters have a lower solubility in water than cholesterol and are more hydrophobic. They are hydrolyzed by the pancreatic enzyme cholesterol esterase to produce cholesterol and free fatty acids. Cholesterol has vital structural roles in membranes and in lipid metabolism in general. It is a biosynthetic precursor of bile acids, vitamin D, and steroid hormones (glucocorticoids, estrogens, progesterones, androgens and aldosterone). In addition, it contributes to the development and functioning of the central nervous system, and it has major functions in signal transduction and sperm development. Cholesterol is a ubiquitous component of all animal tissues where much of it is located in the membranes, although it is not evenly distributed. The highest proportion of unesterified cholesterol is in the plasma membrane (roughly 30-50\\\\% of the lipid in the membrane or 60-80\\\\% of the cholesterol in the cell), while mitochondria and the endoplasmic reticulum have very low cholesterol contents. Cholesterol is also enriched in early and recycling endosomes, but not in late endosomes. The brain contains more cholesterol than any other organ where it comprises roughly a quarter of the total free cholesterol in the human body. Of all the organic constituents of blood, only glucose is present in a higher molar concentration than cholesterol. Cholesterol esters appear to be the preferred form for transport in plasma and as a biologically inert storage (de-toxified) form. They do not contribute to membranes but are packed into intracellular lipid particles. Cholesterol molecules (i.e. cholesterol esters) are transported throughout the body via lipoprotein particles. The largest lipoproteins, which primarily transport fats from the intestinal mucosa to the liver, are called chylomicrons. They carry mostly triglyceride fats and cholesterol that are from food, especially internal cholesterol secreted by the liver into the bile. In the liver, chylomicron particles give up triglycerides and some cholesterol. They are then converted into low-density lipoprotein (LDL) particles, which carry triglycerides and cholesterol on to other body cells. In healthy individuals, the LDL particles are large and relatively few in number. In contrast, large numbers of small LDL particles are strongly associated with promoting atheromatous disease within the arteries. (Lack of information on LDL particle number and size is one of the major problems of conventional lipid tests.). In conditions with elevated concentrations of oxidized LDL particles, especially small LDL particles, cholesterol promotes atheroma plaque deposits in the walls of arteries, a condition known as atherosclerosis, which is a major contributor to coronary heart disease and other forms of cardiovascular disease. There is a worldwide trend to believe that lower total cholesterol levels tend to correlate with lower atherosclerosis event rates (though some studies refute this idea). As a result, cholesterol has become a very large focus for the scientific community trying to determine the proper amount of cholesterol needed in a healthy diet. However, the primary association of atherosclerosis with c... Constituent either free or as esters, of fish liver oils, lard, dairy fats, egg yolk and bran Cholesterol is the major sterol in mammals. It is making up 20-25\\% of structural component of the plasma membrane. Plasma membranes are highly permeable to water but relatively impermeable to ions and protons. Cholesterol plays an important role in determining the fluidity and permeability characteristics of the membrane as well as the function of both the transporters and signaling proteins[1][2].

Phenol
Phenol, is a toxic, colourless crystalline solid with a sweet tarry odor that resembles a hospital smell. It is commonly used as an antiseptic and disinfectant. It is active against a wide range of micro-organisms including some fungi and viruses, but is only slowly effective against spores. It has been used to disinfect skin and to relieve itching. Phenol is also used in the preparation of cosmetics including sunscreens, hair dyes, and skin lightening preparations. It is also used in the production of drugs (it is the starting material in the industrial production of aspirin), weedkillers, and synthetic resins. Phenol can be found in areas with high levels of motor traffic, therefore, people living in crowded urban areas are frequently exposed to traffic-derived phenol vapor. The average (mean +/- SD) phenol concentration in urine among normal individuals living in urban areas is 7.4 +/- 2.2 mg/g of creatinine. Exposure of the skin to concentrated phenol solutions causes chemical burns which may be severe; in laboratories where it is used, it is usually recommended that polyethylene glycol solution is kept available for washing off splashes. Notwithstanding the effects of concentrated solutions, it is also used in cosmetic surgery as an exfoliant, to remove layers of dead skin (Wikipedia). In some bacteria phenol can be directly synthesized from tyrosine via the enzyme tyrosine phenol-lyase [EC:4.1.99.2]. It can be produced by Escherichia and Pseudomonas. Phenol has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). It is used as a flavouring agent in a few foods, at maximum levels below 10 ppm

D-Alanine
Alanine is a nonessential amino acid made in the body from the conversion of the carbohydrate pyruvate or the breakdown of DNA and the dipeptides carnosine and anserine. It is highly concentrated in muscle and is one of the most important amino acids released by muscle, functioning as a major energy source. Plasma alanine is often decreased when the BCAA (Branched Chain Amino Acids) are deficient. This finding may relate to muscle metabolism. Alanine is highly concentrated in meat products and other high-protein foods like wheat germ and cottage cheese. Alanine is an important participant as well as regulator in glucose metabolism. Alanine levels parallel blood sugar levels in both diabetes and hypoglycemia, and alanine reduces both severe hypoglycemia and the ketosis of diabetes. It is an important amino acid for lymphocyte reproduction and immunity. Alanine therapy has helped dissolve kidney stones in experimental animals. Normal alanine metabolism, like that of other amino acids, is highly dependent upon enzymes that contain vitamin B6. Alanine, like GABA, taurine and glycine, is an inhibitory neurotransmitter in the brain. Alanine can be found in some Gram-positive bacteria (PMID:24752840). Amino acids are one of the most important molecules in living organisms, and most of them have a chiral carbon at a -position. In the higher animals, a large part of the naturally occurring amino acids is the L-form, and the stereoisomers (D-amino acids) had been believed to be rare. However, several D-amino acids have been found in mammals including humans, and their distributions, functions and origins have gradually been clarified. The D-alanine (D-Ala) amounts have also been reported to change in the case of diseases. Proteins of the frontal lobe white and gray matter of human brains, both normal and Alzheimer subjects, contain D-alanine at concentrations between 0.50 and 1.28 mumol/g of wet tissue, 50-70-times lower than the concentration of L-alanine. D-Alanine have been detected in the sera of both normal subjects and patients with renal dysfunction, and their concentrations were higher in the patients than in the normal subjects.

Alanine
An alpha-amino acid that consists of propionic acid bearing an amino substituent at position 2. Alanine (symbol Ala or A),[4] or α-alanine, is an α-amino acid that is used in the biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to the central carbon atom which also carries a methyl group side chain. Consequently it is classified as a nonpolar, aliphatic α-amino acid. Under biological conditions, it exists in its zwitterionic form with its amine group protonated (as −NH + 3 ) and its carboxyl group deprotonated (as −CO − 2 ). It is non-essential to humans as it can be synthesized metabolically and does not need to be present in the diet. It is encoded by all codons starting with GC (GCU, GCC, GCA, and GCG). The L-isomer of alanine (left-handed) is the one that is incorporated into proteins. L-alanine is second only to L-leucine in rate of occurrence, accounting for 7.8\\\\\% of the primary structure in a sample of 1,150 proteins.[5] The right-handed form, D-alanine, occurs in peptides in some bacterial cell walls[6]: 131 (in peptidoglycan) and in some peptide antibiotics, and occurs in the tissues of many crustaceans and molluscs as an osmolyte. D-Alanine is a weak GlyR (inhibitory glycine receptor) and PMBA agonist, with an EC50 of 9 mM for GlyR.
