Beta-Tyrosine

3-Amino-3-(4-hydroxyphenyl)propionic acid

C9H11NO3 (181.0738896)


The use of tyrosine kinase receptor inhibitors is increasingly becoming a valuable therapeutic alternative in tumors carrying activated tyrosine kinase receptors. GMR beta tyrosine residues are not necessary for activation of the JAK/STAT pathway, or for proliferation, viability, or adhesion signaling in Ba/F3 cells, although tyrosine residues significantly affect the magnitude of the response.

Beta-Alanine

Omega-aminopropionic acid

C3H7NO2 (89.0476762)


beta-Alanine is the only naturally occurring beta-amino acid - an amino acid in which the amino group is at the beta-position from the carboxylate group. It is formed in vivo by the degradation of dihydrouracil and carnosine. It is a component of the naturally occurring peptides carnosine and anserine and also of pantothenic acid (vitamin B-5), which itself is a component of coenzyme A. Under normal conditions, beta-alanine is metabolized into acetic acid. beta-Alanine can undergo a transanimation reaction with pyruvate to form malonate-semialdehyde and L-alanine. The malonate semialdehyde can then be converted into malonate via malonate-semialdehyde dehydrogenase. Malonate is then converted into malonyl-CoA and enter fatty acid biosynthesis. Since neuronal uptake and neuronal receptor sensitivity to beta-alanine have been demonstrated, beta-alanine may act as a false transmitter replacing gamma-aminobutyric acid. When present in sufficiently high levels, beta-alanine can act as a neurotoxin, a mitochondrial toxin, and a metabotoxin. A neurotoxin is a compound that damages the brain or nerve tissue. A mitochondrial toxin is a compound that damages mitochondria and reduces cellular respiration as well as oxidative phosphorylation. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of beta-alanine are associated with at least three inborn errors of metabolism, including GABA-transaminase deficiency, hyper-beta-alaninemia, and methylmalonate semialdehyde dehydrogenase deficiency. beta-Alanine is a central nervous system (CNS) depressant and is an inhibitor of GABA transaminase. The associated inhibition of GABA transaminase and displacement of GABA from CNS binding sites can also lead to GABAuria (high levels of GABA in the urine) and convulsions. In addition to its neurotoxicity, beta-alanine reduces cellular levels of taurine, which are required for normal respiratory chain function. Cellular taurine depletion is known to reduce respiratory function and elevate mitochondrial superoxide generation, which damages mitochondria and increases oxidative stress (PMID: 27023909). Individuals suffering from mitochondrial defects or mitochondrial toxicity typically develop neurotoxicity, hypotonia, respiratory distress, and cardiac failure. beta-Alanine is a biomarker for the consumption of meat, especially red meat.

Beta-Leucine

(±)-3-Amino-4-methylpentanoic acid, (±)-3-Amino-4-methylvaleric acid

C6H13NO2 (131.0946238)


Beta-leucine is a metabolite that is in the middle of a controversy over its presence in the human body. While there are reports that claim it as a human metabolite, there are others that deny its existence. Two examples:. Circulating levels of beta-leucine are elevated in the cobalamin-deficient state of pernicious anemia. Levels of leucine, on the other hand, are much lower. It is proposed that leucine 2,3-aminomutase, the cobalamin-dependent enzyme that catalyzes the interconversion of leucine and beta-leucine, is the affected enzyme in pernicious anemia and causes these results by preventing the synthesis of leucine from beta-leucine. The synthesis of leucine by human leukocytes and hair roots and by rat liver extracts has been shown to occur when either branched chain fatty acids or valine metabolites are the substances. The synthesis is dependent upon adenosylcobalamin and is inhibited by intrinsic factor (PMID:7430116). Using forms of beta-leucine and leucine that contain several deuterium atoms in place of several hydrogen atoms as internal standards, techniques have been developed which make it possible to detect and quantitate as little as 0.1 mumol/liter of beta-leucine or leucine in human serum and in incubations containing rat liver supernatant. beta-Leucine was not detectable, i.e. less than 0.1 mumol/liter, in any sera from 50 normal human subjects or in any sera from 50 cobalamin-deficient patients. Experiments in which beta-leucine, leucine, isostearic acid, or isocaproic acid were incubated with rat liver supernatant in the presence or absence of adenosylcobalamin or cobalamin-binding protein failed to demonstrate the formation of leucine or beta-leucine or their interconversion under any of the conditions studied. We conclude that beta-leucine is not present in human blood and that the existence of leucine 2,3-aminomutase in mammalian tissues remains to be established (PMID 3356699). Beta-leucine is found to be associated with cobalamin deficiency, which is an inborn error of metabolism. Beta-leucine is a metabolite that is in the middle of a controversy over its presence in the human body.

C11H23N2O7PS (358.09635380000003)


Pantetheine 4-phosphate, or 4-phosphopantetheine, is a metabolite in the pantothenate and coenzyme A biosynthesis pathway. It can be generated from Pantatheine (via pantothenate kinase 1) or R-4-Phospho-pantothenoyl-L-cysteine (via phosphopantothenoylcysteine decarboxylase) or Dephospho-CoA (via 4-phosphopantetheine adenylyl-transferase and ectonucleotide pyrophosphatase). In most mammals, coenzyme A can be hydrolyzed to pantetheine and pantothenate in the intestinal lumen via the following series of reactions: coenzyme A leads to phosphopantetheine leads to pantetheine leads to pantothenate. The conversion of 4-phosphopantetheine (4-PP) to dephospho-CoA, is catalyzed by 4-phosphopantetheine adenylyl-transferase. In mammalian systems, this step may occur in the mitochondria or in the cytosol. (PMID: 1746161) It has been identified as an essential cofactor in in the biosynthesis of fatty acids, polyketides, depsipeptides, peptides, and compounds derived from both carboxylic and amino acid precursors. In particular it is a key prosthetic group of acyl carrier protein (ACP) and peptidyl carrier proteins (PCP) and aryl carrier proteins (ArCP) derived from Coenzyme A. Phosphopantetheine fulfils two demands. Firstly, the intermediates remain covalently linked to the synthases (or synthetases) in an energy-rich thiol ester linkage. Secondly, the flexibility and length of phosphopantetheine chain (approximately 2 nm) allows the covalently tethered intermediates to have access to spatially distinct enzyme active sites. 4-phosphopantetheine is a metabolite in the pantothenate and coenzyme A biosynthesis pathway.

N-[(2R)-2-Hydroxy-3,3-dimethyl-1-oxo-4-(phosphonooxy)butyl]-beta-alanine

C9H18NO8P (299.0769998)

(S)-beta-Aminoisobutyric acid

(S)-3-amino-2-Methyl-propanoic acid

C4H9NO2 (103.0633254)


beta-Aminoisobutyric acid is a non-protein amino acid originating from the catabolism of thymine and valine. The concentration of beta-aminoisobutyric acid is normally low in urine as beta-aminoisobutyric acid is further catabolized by beta-aminoisobutyrate aminotransferases to methylmalonic acid semialdehyde and propionyl-CoA. beta-Aminoisobutyric acid occurs in two isomeric forms and both enantiomers of beta-aminoisobutyric acid can be detected in human urine and plasma. In plasma, the S-enantiomer is the predominant type due to active renal reabsorption. In contrast, urine almost exclusively contains the R-enantiomer of beta-aminoisobutyric acid, which is eliminated both by filtration and tubular secretion. Persistently increased levels of beta-aminoisobutyric acid have been observed in individuals with a deficiency of R (-)-beta-aminoisobutyrate-pyruvate aminotransferase. In addition, transient high levels of beta-aminoisobutyric acid have been observed under a variety of pathological conditions such as lead poisoning, starvation, in total body irradiation, and in a number of malignancies. The S-enantiomer of beta-aminoisobutyric acid is predominantly derived from the catabolism of valine. It has been suggested that altered homeostasis of beta-alanine underlies some of the clinical abnormalities encountered in patients with a dihydropyrimidine dehydrogenase (DPD) deficiency. DPD constitutes the first step of the pyrimidine degradation pathway, in which the pyrimidine bases uracil and thymine are catabolized to beta-alanine and the R-enantiomer of beta-aminoisobutyric acid respectively. In normal individuals with an intact pyrimidine degradation pathway, R-methylmalonic acid semialdehyde can be synthesized directly from the catabolism of thymine. Hence, there might be less cross-over between the valine and thymine pathway, allowing the conversion of S-methylmalonic acid semialdehyde into S-beta-aminoisobutyric acid and the subsequent accumulation of S-beta-aminoisobutyric acid in plasma (PMID: 14705962, 14292857, 14453202). (S)-b-aminoisobutyric acid is a non-protein amino acid originating from the catabolism of thymine and valine.

C22H42N4O8S2 (554.2443932)


D-Pantethine, also known as pantetina or pantomin, belongs to the class of organic compounds known as beta amino acids and derivatives. These are amino acids having a (-NH2) group attached to the beta carbon atom. Most vitamin B5 supplements are in the form of calcium pantothenate, a salt of pantothenic acid, with doses in the range of 5 to 10 mg/day. Pantethine is available in the United States as a dietary supplement because of evidence of its health benefits for lowering elevated LDL-cholesterol and triglycerides, and raising HDL-cholesterol (the good cholesterol). In contrast, pantethine is sold as a dietary supplement for lowering blood cholesterol and triglycerides at doses of 500 to 1200 mg/day. These clinical trials were conducted with daily intakes ranging from 600 to 1200 mg/day. Pantethine (bis-pantethine or co-enzyme pantethine) is a dimeric form of pantetheine, which is produced from pantothenic acid (vitamin B5) by the addition of cysteamine. D-Pantethine is a drug. Pantetheine is an intermediate in the production of coenzyme A by the body. In multiple clinical trials of patients with elevated cholesterol and triglycerides, total and LDL cholesterol were decreased by an average of 12\\\%, triglycerides decreased by 19\\\%, and HDL cholesterol was increased by 9\\\%. Pantethine is composed of two molecules of pantetheine linked by a bridging disulfide. Most of the literature on pantethine and lipids is 20 to 30 years old, but recent carefully controlled trials of 600 and 900 mg/d doses have shown similar statistically significant lowering of LDL cholesterol in individuals with greatly or moderately elevated levels of blood lipids. A few trials conducted in Japan tested 300 mg/day and reported decreases in total cholesterol of about 4\\\%, increases in HDL-cholesterol of 5\\\% and inconsistent results for triglycerides. Direct dose-response evidence is not available because no trial tested more than one dose. Within this dose range there is no evidence of a dose-effect relationship, i.e. changes in lipid concentrations overlapped across the range of doses. Pantethine (Bis-pantethine) or "Co-enzyme pantethine" is a dimeric form of vitamin B5, composed of two molecules of pantothenic acid linked by cysteamine bridging groups. The monomer of this compound is known as pantetheine and is an intermediate in the production of Coenzyme A by the body. Pantethine is considered the more biologically active form of vitamin B5, but is less stable than pantothenic acid and tends to decompose over time if it is not kept refrigerated, so most vitamin B5 supplements are in the form of calcium pantothenate.

Pantothenic acid is a water-soluble vitamin. For many animals, pantothenic acid is an essential nutrient. Only the dextrorotatory (D) isomer of pantothenic acid possesses biologic activity. The levorotatory (L) form may antagonize the effects of the dextrorotatory isomer. Pantothenic acid is found in many foods, some of which are cream substitute, yellow bell pepper, corn, and atlantic mackerel. D018977 - Micronutrients > D014815 - Vitamins D-Pantothenic acid (Pantothenate) is an essential trace nutrient that functions as the obligate precursor of coenzyme A (CoA). D-Pantothenic acid plays key roles in myriad biological processes, including many that regulate carbohydrate, lipid, protein, and nucleic acid metabolism[1].
