Common industrial routes include hydrogenation of maleic acid, oxidation of 1,4-butanediol, and carbonylation of ethylene glycol. [7] For dendritic cells, succinate functions as a chemoattractant and increases their antigen-presenting function via receptor stimulated cytokine production. [7] Succinate may thus be produced from enhanced glutamine metabolism via alpha-ketoglutarate or the GABA shunt. [42] The other two oncometabolites, fumarate and 2-hydroxyglutarate have similar structures to succinate and function through parallel HIF-inducing oncogenic mechanisms. ADS stream Struct. Article Since our excess is very low, our substance was nowhere near being pure. Under anaerobic conditions certain bacteria such as A. succinogenes, A. succiniciproducens and M. succiniciproducens, run the TCA cycle in reverse and convert glucose to succinate through the intermediates of oxaloacetate, malate and fumarate.

[12] Drugs involving succinate include metoprolol succinate, sumatriptan succinate, Doxylamine succinate or solifenacin succinate. Material Safety Data Sheet - Fisher Sci [citation needed], Succinate is one of three oncometabolites, metabolic intermediates whose accumulation causes metabolic and non-metabolic dysregulation implicated in tumorigenesis. Enantioseparation of Phenylsuccinic Acid Enantiomers by Solvent [8][29] During ischemia, succinate accumulates. The Index number for each substance is in the form of a digit sequence of the type ABC-RST-VW-Y. Enantiomeric excess: of (+)-phenylsuccinic acid, To comprehend the conversion of an enantiomer to a di-astereomer, enantiomers are identical while diastereomers are not so they can be created by reacting a mixture of both enantiomers with another chiral molecule. indication of why you can't access this Colby College website. [36] Pathologically elevated levels of succinate lead to hypermethylation, epigenetic silencing and changes in neuroendocrine differentiation, potentially driving cancer formation. In order to recrystallize the. Add 1.15g of finely ground (s)-proline & a magnetic stir bar then mix contents for 2 minutes and reflux for 30 minutes. A key candidate transporter is INDY (I'm not dead yet), a sodium-independent anion exchanger, which moves both dicarboxylate and citrate into the bloodstream. Vacuum filter and wash the solid with two 15mL volumes of cold water. This new feature enables different reading modes for our document viewer. On this Wikipedia the language links are at the top of the page across from the article title. This is simple since neutral phenylsuccinic acid is poorly soluble in water. [26] As such, succinate links TCA cycle dysfunction or metabolic changes to cell-cell communication and to oxidative stress-related responses. 7, 1291 (2007). [41], Succinate accumulation under hypoxic conditions has been implicated in the reperfusion injury through increased ROS production. Molecular Formula:C10H10O4 Molecular Weight:194.19 Section 10 - Stability and Reactivity [30], Extracellular succinate can act as a signaling molecule with hormone-like function, targeting a variety of tissues such as blood cells, adipose tissue, immune cells, the liver, the heart, the retina and primarily the kidney. The toxicological properties of this material have Think of a chinal center as an atom to which four different groups are covalently attached. Succinic acid (/sksnk/) is a dicarboxylic acid with the chemical formula (CH2)2(CO2H)2. As the anion binds the H+, it loses its negative charge and becomes poorly soluble in water. Dicarboxylic acids are ubiquitous in atmospheric aerosol particles, but their roles as surfactants in cloud condensation nuclei (CCN) activity remain unclear. One proline has a position available for one extra proton, so the two protons end up on two different prolines. The solid that results is now-resolved phenylsuccinic acid in its protonated form. For Research Use Only. The acid and base are structurally more complex than HCl and NH3, but the concept is the same. Single crystal structures, thermal analysis, powder X-ray analysis and equilibrium solubility in water and ethanol of the cocrystals were measured. [30], Succinate signaling often occurs in response to hypoxic conditions.

Lab8_PhenylsuccinicAcid_handout_F20.pdf - OPTICAL [35] Succinate may interfere with the enzymatic process by attaching to the Fe(II) center first, prohibiting the binding of 2-oxoglutarate. CHEM: Organic Chemistry Labora- - 173.212.249.81. RECEIVE -15-CRUZ CREDITS. The phenylsuccinic acid is a proton donor making proline the proton acceptor. Google Scholar. Allow the flask to air-cool about 10 min. 4, 339 (2007). Finally, succinic semialdehyde is oxidized by succinic semialdehyde dehydrogenase (SSADH) to form succinate, re-entering the TCA cycle and closing the loop. [14] Succinate can be used to derive 1,4-butanediol, maleic anhydride, succinimide, 2-pyrrolidinone and tetrahydrofuran. Google Scholar. 1 0 obj [6][23] Under conditions of succinate accumulation, rapid oxidation of succinate by SDH can drive reverse electron transport (RET). 1035, 203 (2013). How does one obtain optically active compounds? Not Intended for Diagnostic or Therapeutic Use.

Molecular Formula:C10H10O4 Molecular Weight:194.19 Section 10 - Stability and Reactivity Chemical Stability:Stable under normal temperatures and pressures. [30] In general, leakage from the mitochondria requires succinate overproduction or underconsumption and occurs due to reduced, reverse or completely absent activity of SDH or alternative changes in metabolic state. : an American History (Eric Foner), Forecasting, Time Series, and Regression (Richard T. O'Connell; Anne B. Koehler), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. Less The diastereomeric salt formed between the (+)-phenylsuccinic acid and (-)-proline is much ___ soluble in isopropyl alcohol than the diastereomeric salt formed between the . Succinate thus serves as a direct electron donor to the electron transport chain, and itself is converted into fumarate. The solid that results is now-resolved phenylsuccinic acid in its protonated form. It now must be recovered from the salt (the second step). The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. Because protons have +1 charge, each proline is cationic. [8] ROS then trigger the cellular apoptotic machinery or induce oxidative damage to proteins, membranes, organelles etc. 1).Factors affecting the extraction efficiency were investigated, namely the influence of the types of organic solvents and -CD derivatives, iso-butyl tartrate . [12][13], Succinic acid can be dehydrogenated to fumaric acid or be converted to diesters, such as diethylsuccinate (CH2CO2CH2CH3)2. If you have any questions phenylsuccinic salt Not Intended for Diagnostic or Therapeutic Use. The impact of chirality is assessed via comparison of structural features and properties of binary cocrystals. In addition to its metabolic roles, succinate serves as an intracellular and extracellular signaling molecule. The recovered solid is the less-soluble diastereomeric salt of the pair that you made. Struct. The solid that results is now-resolved phenylsuccinic acid in its protonated form. Optically active reagents have long been important in studies of reaction mechanisms because they may offer glimpses at the molecular details of the process as the reaction proceeds. C. C. Seaton, CrystEngComm 13, 6583 (2011). Most often, these pieces can attach to the enzyme only in one particular, orientation. https://doi.org/10.1134/S1063774519070125. So, for optical activity to be evident, there must be an excess of one enantiomer over its mirror image. Enantiomeric excess: 60.65171=0 100 =35% of (+)-phenylsuccinic acid phenylsuccinic acid (H 2A) as the model enantiomers. A. V. Trask, N. Shan, W. D. S. Motherwell, et al., Chem. Enantiomers are distinguished from cach other by designations like "R" or "S", "D" or "L", or by the direction of the rotation they cause ("+" or "-") Since the presence of optical activity is an indication of a particular configuration of atoms, any change in optical activity that occurs during a chemical reaction offers a way to study the kind of configurational change that accompanies the reaction. Oxidative decarboxylation then generates a ferryl intermediate coordinated to succinate, which serves to oxidize the bound primary substrate. [30], In adipocytes, the succinate-activated GPR91 signaling cascade inhibits lipolysis. 5.03E-005 mm Hg (25 deg C, Mod-Grain method) Water Solubility Estimate from Log Kow (WSKOW v1.41): Water Solubility at 25 deg C (mg/L): 4.234e+004 log Kow .

Not Intended for Diagnostic or Therapeutic Use. Heat and gently swirl the mixture on the hot plate until all the solid dissolves (add a little more water if the entire solid is not in solution just as the solution begins to gently boil). The phenylsuccinic acid would bind to the proton (H+), where it loses its negative charge and becomes insoluble in water. [10] 1,4-Butanediol (BDO) can be synthesized using succinic acid as a precursor. [11], Genetically engineered Escherichia coli and Saccharomyces cerevisiae are proposed for the commercial production via fermentation of glucose. The phenylsuccinic acid is a proton donor making proline the proton acceptor. Part of their specificity lies in how they bind, or attract and hold, the molecular pieces that are to be fashioned into the product. Chirality is a necessary condition for the existence of optical activity (the ability to cause rotation of the plane of polarized light).
