[40] In spite of a general downregulation of the TCA cycle under these conditions, succinate concentration is increased. The enantiomeric excess (ee) can be calculated with the expression above, where []mixture and []pureenantiomer are the specific rotations of th. ;DgEvzv {M aK. The reaction between the bis salt of proline and phenylsuccinic acid will give free phenyl succinic acid and proline hydrochloride as HCl is a much stronger acid than phenylsuccinic acid. [27] The GABA shunt serves as an alternate route to convert alpha-ketoglutarate into succinate, bypassing the TCA cycle intermediate succinyl-CoA and instead producing the intermediate GABA. 9, 1436 (2009). Thus, via enzymatic inhibition, increased succinate load can lead to changes in transcription factor activity and genome-wide alterations in histone and DNA methylation. Succinate exits the mitochondrial matrix and passes through the inner mitochondrial membrane via dicarboxylate transporters, primarily SLC25A10, a succinate-fumarate/malate transporter. Stir for 5 min to allow complete protonation. The recovered diastereomer must be converted back to the original compound from which it was made -- now a single enantiomer. In the retina, succinate accumulates in retinal ganglion cells in response to ischemic conditions. In humans, three HIF prolyl 4-hydroxylases regulate the stability of HIFs. 7, 1291 (2007). M. Yoshimura, M. Miyake, T. Kawato, et al., Cryst. [6] It is marketed as food additive E363. Growth Des. Mass of product dissolved in acetone: 0 Soluble in acetone, alcohols, and methanol. Add a magnetic stir bar and gently mix the contents of the flask until you achieve a tical while diastereomers are not stacking interaction leads to the formation of 3D supramolecular structure.

If you study models of chiral molecules, it soon becomes apparent that their mirror images are not superposable on each other. Inhibition of KDMs and TET hydroxylases results in epigenetic dysregulation and hypermethylation affecting genes involved in cell differentiation. The phenylsuccinic acid is a proton donor making proline the proton acceptor. [27], Succinate is produced and concentrated in the mitochondria and its primary biological function is that of a metabolic intermediate. Molecular Formula:C10H10O4 Molecular Weight:194.19 Section 10 - Stability and Reactivity Commun. omeric salt was isolated, the enantiomer of phenylsuccinic acid remains. [33] Therapies targeting succinate to reduce cardiovascular risk and hypertension are currently under investigation.[28]. Solubility: Not available. Succinic acid is a white, odorless solid with a highly acidic taste. As the anion binds the H+, it loses its negative charge and becomes poorly soluble in water. [6] The intermediate is made available for biosynthetic processes through multiple pathways, including the reductive branch of the TCA cycle or the glyoxylate cycle, which are able to drive net production of succinate. [12] As an excipient in pharmaceutical products, it is also used to control acidity[21] or as a counter ion. 48, 5009 (2006). Measure the specific rotation and determine the enantiomeric excess of the sample. [ 1], Succinate can alternatively be formed by reverse activity of SDH. InChI=1S/C4H6O4/c5-3(6)1-2-4(7)8/h1-2H2,(H,5,6)(H,7,8), InChI=1/C4H6O4/c5-3(6)1-2-4(7)8/h1-2H2,(H,5,6)(H,7,8), Except where otherwise noted, data are given for materials in their, Precursor to polymers, resins, and solvents. In living organisms, succinic acid takes the form of an anion, succinate, which has multiple biological roles as a metabolic intermediate being converted into fumarate by the enzyme succinate dehydrogenase in complex 2 of the electron transport chain which is involved in making ATP, and as a signaling molecule reflecting the cellular metabolic state. Solubility:Not available. [36] Additionally, succinate-promoted activation of HIF-1 generates a pseudo-hypoxic state that can promote tumorneogensis by transcriptional activation of genes involved in proliferation, metabolism and angiogenesis. ACD/Labs Percepta Platform - PhysChem Module, US Environmental Protection Agencys EPISuite, Compounds with the same molecular formula, Search Google for structures with same skeleton, CAUTION: May irritate eyes, skin, and respiratory tract. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. For Research Use Only. 2) Calculate the enantiomeric excess if the specific rotation obtained after recrystallization is 103.2. Add 1.73 g of (-)-proline. It is also available as a flavoring agent, contributing a somewhat sour and astringent component to umami taste. Resulting in observing another groups data: This involves an acid-base reaction with (s)-proline and restor- RECEIVE -15-CRUZ CREDITS. [citation needed], Succinate is a key intermediate in the tricarboxylic acid cycle, a primary metabolic pathway used to produce chemical energy in the presence of O2.

[42] The other two oncometabolites, fumarate and 2-hydroxyglutarate have similar structures to succinate and function through parallel HIF-inducing oncogenic mechanisms. Crystallogr. 20, 2372 (2002). Correspondence to GABA is then metabolized by GABA transaminase to succinic semialdehyde. Experimental Procedure: It now must be recovered from the salt (the second step). As a consequence, the mixture cases no net rotation, and appears optically inactive. Chronic: Who are the experts? Stir the mixture with a glass rod for 5 minutes. Soc. DL-Phenylsuccinic acid Revision Date 24-Dec-2021 Notification Requirements Butanedioic acid, phenyl- 635-51-8 Not applicableNot applicableNot applicableNot applicable 16. With the product collected, specific rotation was calculated where polarimetry is used to calculate the alpha observed in degrees. High concentrations of succinate will mimic the hypoxia state by suppressing PHDs,[37] therefore stabilizing HIF1 and inducing the transcription of HIF1-dependent genes even under normal oxygen conditions. : 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. produced two diastereomers Chirality is a necessary condition for the existence of optical activity (the ability to cause rotation of the plane of polarized light). The solid that results is now-resolved phenylsuccinic acid in its protonated form. Transamination and subsequent decarboxylation of alpha-ketoglutarate leads to the formation of GABA. [24] This pathway is exploited in metabolic engineering to net generate succinate for human use. [32] Arg99, His103, Arg252, and Arg281 near the center of the receptor generate a positively charged binding site for succinate. Organic Chemistry I Cool 10mL of 6.0 M HCl in an ice bath and add all of the collected salt to this cold HCl. After refluxing, cool flask for 15 minutes, vacuum filter the reaction mixture & wash salt with 2 15mL of acetone. N. Shan, A. D. Bond, and W. Jones, Cryst. A 71, 3 (2015). [30] Transport across the plasma membrane is likely tissue specific. Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01. [16] The automotive and electronics industries heavily rely on BDO to produce connectors, insulators, wheel covers, gearshift knobs and reinforcing beams. Given that enantiomers have identical physical properties, how can the mirror-image molecules become separated without the aid of some living thing? The less soluble salt may precipitate. with another chiral molecule. To place an order using RMB or to ship to mainland China, please visit www.scbio.cn, Click on image or enlarge button to enlarge. [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 solid was recrystallized and the final solid is filtered out. of one compound from a mixture of compounds. They are potentially separable by ordinary physical methods like different solubility in a given solvent, which allows recovery of a single diastereomer ACD/Labs Percepta Platform - PhysChem Module, US Environmental Protection Agencys EPISuite, Compounds with the same molecular formula, Search Google for structures with same skeleton, CAUTION: May irritate eyes, skin, and respiratory tract. Optical Rotation: []=obscl[]=(0.03992/m)( 1 )=60 This specificity of attachment means that the atoms of the product always end up being connected to each other in only one of several possible ways. CAS Number: 635-51-8. Oxidative decarboxylation then generates a ferryl intermediate coordinated to succinate, which serves to oxidize the bound primary substrate. Scratch inside this test tube several minutes until the contents begin to get cloudy. [30] In the second step of mitochondrial export, succinate readily crosses the outer mitochondrial membrane through porins, nonspecific protein channels that facilitate the diffusion of molecules less than 1.5 kDa. T. Friscic, L. Fabian, J. C. Burley, et al., Chem. The resulting solid acid can be recovered by filtration. May cause irritation of the digestive tract. Cloudiness and then crystals should gradually form.) Percent recovery: 00 100 =4% [39] Other inflammatory cytokines produced by activated macrophages such as tumor necrosis factor or interleukin 6 are not directly affected by succinate and HIF1. The recovered solid is the less-soluble diastereomeric salt of the pair that you made. was removed by the HCl. The phenylsuccinic acid gave up two positives, so it is a dianion.
