5-Aminopentanoic acid

5-Aminovaleric acid hydrochloride

C5H11NO2 (117.079)


5-Aminopentanoic acid (or 5-aminovalerate) is a lysine degradation product. It can be produced both endogenously or through bacterial catabolism of lysine. 5-aminovalerate is formed via the following multi-step reaction: L-lysine leads to cadverine leads to L-piperideine leads 5-aminovalerate (PMID:405455). In other words it is a metabolite of cadaverine which is formed via the intermediate, 1-piperideine (PMID:6436440). Cadaverine is a foul-smelling diamine compound produced by protein hydrolysis during putrefaction of animal tissue. High levels of 5-aminovalerate in biofluids may indicate bacterial overgrowth or endogenous tissue necrosis. In most cases endogenous 5-aminovalerate is thought to be primarily a microbial metabolite produced by the gut or oral microflora, although it can be produced endogenously. 5-aminovalerate is a normal metabolite present in human saliva, with a tendency to elevated concentration in patients with chronic periodontitis. Bacterial contamination and decomposition of salivary proteins is primarily responsible for elevated salivary levels (PMID 3481959). Beyond being a general waste product, 5-aminovalerate is also believed to act as a methylene homologue of gamma-aminobutyric acid (GABA) and functions as a weak GABA agonist (PMID:4031870). It is also known as an antifibrinolytic amino acid analog and so it functions as a weak inhibitor of the blood clotting pathway (PMID:6703712). 5- aminovalerate is an in vivo substrate of 4-aminobutyrate:2-oxoglutarate aminotransferase (PMID:4031870). It can be found in Corynebacterium (PMID:27717386). 5-aminopentanoic acid is a normal metabolite present in human saliva, with a tendency to elevated concentration in patients with chronic periodontitis. Bacterial contamination and decomposition of salivary proteins is responsible for the elevated salivary levels (PMID 3481959) [HMDB] 5-Aminovaleric acid. CAS Common Chemistry.

Cytidine triphosphate

({[({[(2R,3S,4R,5R)-5-(4-amino-2-oxo-1,2-dihydropyrimidin-1-yl)-3,4-dihydroxyoxolan-2-yl]methoxy}(hydroxy)phosphoryl)oxy](hydroxy)phosphoryl}oxy)phosphonic acid

C9H16N3O14P3 (482.9845)


Cytidine triphosphate (CTP), also known as 5-CTP, is pyrimidine nucleoside triphosphate. Formally, CTP is an ester of cytidine and triphosphoric acid. It belongs to the class of organic compounds known as pentose phosphates. These are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. CTP, much like ATP, consists of a base (cytosine), a ribose sugar, and three phosphate groups. CTP is a high-energy molecule similar to ATP, but its role as an energy coupler is limited to a much smaller subset of metabolic reactions. CTP exists in all living species, ranging from bacteria to plants to humans and is used in the synthesis of RNA via RNA polymerase. Another enzyme known as cytidine triphosphate synthetase (CTPS) mediates the conversion of uridine triphosphate (UTP) into cytidine triphosphate (CTP) which is the rate-limiting step of de novo CTP biosynthesis. CTPS catalyzes a complex set of reactions that include the ATP-dependent transfer of the amide nitrogen from glutamine (i.e., glutaminase reaction) to the C-4 position of UTP to generate CTP. GTP stimulates the glutaminase reaction by accelerating the formation of a covalent glutaminyl enzyme intermediate. CTPS activity regulates the intracellular rates of RNA synthesis, DNA synthesis, and phospholipid synthesis. CTPS is an established target for a number of antiviral, antineoplastic, and antiparasitic drugs. CTP also acts as an inhibitor of the enzyme known as aspartate carbamoyltransferase, which is used in pyrimidine biosynthesis. CTP also reacts with nitrogen-containing alcohols to form coenzymes that participate in the formation of phospholipids. In particular, CTP is the direct precursor of the activated, phospholipid pathway intermediates CDP-diacylglycerol, CDP-choline, and CDP-ethanolamine ((PMID: 18439916). CDP-diacylglycerol is the source of the phosphatidyl moiety for phosphatidylserine, phosphatidylethanolamine, and phosphatidylcholine (synthesized by way of the CDP-diacylglycerol pathway) as well as phosphatidylglycerol, cardiolipin, and phosphatidylinositol (PMID: 18439916). Cytidine triphosphate, also known as 5-ctp or cytidine 5-triphosphoric acid, 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. Cytidine triphosphate is soluble (in water) and an extremely strong acidic compound (based on its pKa). Cytidine triphosphate can be found in a number of food items such as lowbush blueberry, black radish, american pokeweed, and cherry tomato, which makes cytidine triphosphate a potential biomarker for the consumption of these food products. Cytidine triphosphate can be found primarily in cellular cytoplasm, as well as throughout all human tissues. Cytidine triphosphate exists in all living species, ranging from bacteria to humans. In humans, cytidine triphosphate is involved in several metabolic pathways, some of which include cardiolipin biosynthesis cl(i-14:0/i-17:0/i-16:0/i-21:0), cardiolipin biosynthesis cl(a-13:0/a-21:0/i-22:0/i-17:0), phosphatidylethanolamine biosynthesis PE(18:2(9Z,12Z)/24:0), and cardiolipin biosynthesis cl(i-13:0/a-21:0/a-15:0/i-16:0). Cytidine triphosphate is also involved in several metabolic disorders, some of which include sialuria or french type sialuria, tay-sachs disease, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and g(m2)-gangliosidosis: variant B, tay-sachs disease. Cytidine triphosphate is a high-energy molecule similar to ATP, but its role as an energy coupler is limited to a much smaller subset of metabolic reactions. Cytidine triphosphate is a coenzyme in metabolic reactions like the synthesis of glycerophospholipids and glycosylation of proteins . Cytidine 5′-triphosphate (Cytidine triphosphate; 5'-CTP) is a nucleoside triphosphate and serves as a building block for nucleotides and nucleic acids, lipid biosynthesis. Cytidine triphosphate synthase can catalyze the formation of cytidine 5′-triphosphate from uridine 5′-triphosphate (UTP). Cytidine 5′-triphosphate is an essential biomolecule?in the de novo?pyrimidine biosynthetic pathway in?T. gondii[1].

   

Tetradecanoyl-CoA

{[(2R,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-4-hydroxy-2-({[hydroxy({[hydroxy({3-hydroxy-2,2-dimethyl-3-[(2-{[2-(tetradecanoylsulfanyl)ethyl]carbamoyl}ethyl)carbamoyl]propoxy})phosphoryl]oxy})phosphoryl]oxy}methyl)oxolan-3-yl]oxy}phosphonic acid

C35H62N7O17P3S (977.3136)


Tetradecanoyl-CoA (or myristoyl-CoA) is an intermediate in fatty acid biosynthesis, fatty acid elongation and the beta oxidation of fatty acids. It is also used in the myristoylation of proteins. The first pass through the beta-oxidation process starts with the saturated fatty acid palmitoyl-CoA and produces myristoyl-CoA. A total of four enzymatic steps are required, starting with VLCAD CoA dehydrogenase (Very Long Chain) activity, followed by three enzymatic steps catalyzed by enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and ketoacyl-CoA thiolase, all present in the mitochondria. Myristoylation of proteins is also catalyzed by the presence of myristoyl-CoA along with Myristoyl-CoA:protein N-myristoyltransferase (NMT). Myristoylation is an irreversible, co-translational (during translation) protein modification found in animals, plants, fungi and viruses. In this protein modification a myristoyl group (derived from myristioyl CoA) is covalently attached via an amide bond to the alpha-amino group of an N-terminal amino acid of a nascent polypeptide. It is more common on glycine residues but also occurs on other amino acids. Myristoylation also occurs post-translationally, for example when previously internal glycine residues become exposed by caspase cleavage during apoptosis. Myristoylation plays a vital role in membrane targeting and signal transduction in plant responses to environmental stress. Compared to other species that possess a single functional myristoyl-CoA: protein N-myristoyltransferase (NMT) gene copy, human, mouse and cow possess 2 NMT genes, and more than 2 protein isoforms. Myristoyl-coa, also known as S-tetradecanoyl-coenzyme a or myristoyl-coenzyme a, is a member of the class of compounds known as long-chain fatty acyl coas. Long-chain fatty acyl coas are acyl CoAs where the group acylated to the coenzyme A moiety is a long aliphatic chain of 13 to 21 carbon atoms. Myristoyl-coa is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). Myristoyl-coa can be found in a number of food items such as sea-buckthornberry, anise, chicory, and cassava, which makes myristoyl-coa a potential biomarker for the consumption of these food products. Myristoyl-coa can be found primarily in human fibroblasts tissue. Myristoyl-coa exists in all eukaryotes, ranging from yeast to humans. In humans, myristoyl-coa is involved in few metabolic pathways, which include adrenoleukodystrophy, x-linked, beta oxidation of very long chain fatty acids, and fatty acid metabolism. Myristoyl-coa is also involved in several metabolic disorders, some of which include de novo triacylglycerol biosynthesis TG(18:0/14:0/22:0), de novo triacylglycerol biosynthesis tg(i-21:0/12:0/14:0), de novo triacylglycerol biosynthesis TG(18:1(9Z)/14:0/22:2(13Z,16Z)), and de novo triacylglycerol biosynthesis TG(14:0/16:1(9Z)/22:5(4Z,7Z,10Z,13Z,16Z)).
