In this experiment, a reflux reaction is conducted between the pheny-succinic acid and proline to produce salt. CAS Number: 4036-30-. 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. [6][26] Extra-mitochondrial succinate alters the epigenetic landscape by inhibiting the family of 2-oxogluterate-dependent dioxygenases. [12], In 2004, succinate was placed on the US Department of Energy's list of top 12 platform chemicals from biomass. The recovered diastereomer must be converted back to the original compound from which it was made -- now a single enantiomer. Vacuum filter and wash the solid with two 15mL [32] In inflammatory macrophages, succinate-induced stability of HIF1 results in increased transcription of HIF1-dependent genes, including the pro-inflammatory cytokine interleukin-1. [5], As a radical group it is called a succinyl (/sksnl/) group. Immediately retum the contents to the boiling flask and swirl. [30] The G-protein coupled receptor, GPR91 also known as SUCNR1, serves as the detector of extracellular succinate. [37][41] Loss-of-function mutations in the genes encoding succinate dehydrogenase, frequently found in hereditary paraganglioma and pheochromocytoma, cause pathological increase in succinate. When the solution is completely ho-mogenous, remove the flask from the hot plate and allow to cool. Phenylsuccinic acid (H 2 A, racemate, purity 99 %) was purchased from DiBo (Shanghai, China) and polyethyleneglycol (PEG) was provided by Guangzhou (Guangdong, . out to be a good recrystallization solvent for this product. Nonsuperposable mirror image molecules are called enantiomers. The 'Substance identity' section is calculated from substance identification information from all ECHA databases. Learn more about Institutional subscriptions. The answer lies in converting the mixture of enantiomers into different compounds - a pair of diastereomers (stereoisomers that are not mitror images of each other). Chirality is a necessary condition for the existence of optical activity (the ability to cause rotation of the plane of polarized light). Neutral phenylsuccinic acid is partially soluble in water, so HCl was used as a strong acid to protonate the anion. the proton acceptor. Multiple studies have demonstrated succinate-induced aggregation, but the effect has high inter-individual variability. OPTICAL RESOLUTION OF 2-PHENYLSUCCINIC ACID, (From R. Stephani and V. Cesare, Journal of Chemical Education, The purposes of this experiment are to show how enantiomers can be separated if they are converted into a, mixture of diastereomers and to understand how careful choice of solvent can permit selective precipitation. Stir for 5 min to allow complete protonation. Add 1.15g of finely ground (s)-proline & a magnetic stir bar then mix contents for 2 minutes and reflux for 30 minutes. The first source was natural products chemicals produced by living organisms. G. M. Sheldrick, Acta Crystallogr. Japan (1987), 60, 824-827). Chem. Resulting in observing another groups data: The phenylsuccinic acid gave up two positives, so it is a dianion. Specific rotation is defined as [.." - r/le where "-the specific rotation (at 200C using the "D line" of a sodium lamp: units arc (deg x ml. [24] Additionally, succinic acid produced during the fermentation of sugar provides a combination of saltiness, bitterness and acidity to fermented alcohols. Succinic acid (/ s k s n k /) is a dicarboxylic acid with the chemical formula (CH 2) 2 (CO 2 H) 2. sion of an enantiomer to a di- This involves an acid-base reaction with (s)-proline and restoring the enantiomer by neutralizing the salt created to find the optical purity by measuring the optical rotation using polarimetry. [11], Genetically engineered Escherichia coli and Saccharomyces cerevisiae are proposed for the commercial production via fermentation of glucose. [30] Transport across the plasma membrane is likely tissue specific. [6][26][38] PHDs hydroxylate proline in parallel to oxidatively decarboxylating 2-oxyglutarate to succinate and CO2. Most often, these pieces can attach to the enzyme only in one particular orientation. In humans, three HIF prolyl 4-hydroxylases regulate the stability of HIFs. Alternate Names: Phenylsuccinic acid. Conditions to Avoid:Incompatible materials, dust generation, excess heat, strong oxidants. Zohreh Derikvand. In the liver, succinate serves as a paracrine signal, released by anoxic hepatocytes, and targets stellate cells via GPR91.

A new solvent sublation (SS) system for chiral separation is introduced by using phenylsuccinic acid (H2A) as the model enantiomers. [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. stacking interaction leads to the formation of 3D supramolecular structure. In animal models, pharmacological inhibition of ischemic succinate accumulation ameliorated ischemia-reperfusion injury. In living organisms, primarily succinate, not succinic acid, is found. OPTICAL RESOLUTION OF 2-PHENYLSUCCINIC ACID (From R. Stephani and V. Cesare, Journal of Chemical Education 74, 1226, 1997) 1) Background: The purposes of this experiment are to show how enantiomers can be separated if they are converted into a mixture of diastereomers and to understand how careful choice of solvent can permit selective precipitation of one compound from a mixture of compounds. of this substance have not been fully investigated. T. R. Shattock, K. K. Arora, P. Vishweshwar, and M.J.Zaworotko, Cryst. 4, 310 (2007). ()-phenylsuccinic acid N CO 2H H H (-)-Proline Week 1: Resolution of ()-phenylsuccinic acid Procedure In a clean, dry, 250 mL round-bottomed flask, dissolve 2.9 g of ()-phenylsuccinic acid in 75 mL of 2-propanol. RECEIVE -15-CRUZ CREDITS. [42] The other two oncometabolites, fumarate and 2-hydroxyglutarate have similar structures to succinate and function through parallel HIF-inducing oncogenic mechanisms. To get rid of 2-propanol and any unreacted phenylsuccinic acid, wash the crystals with 10 mL of acetone. in short, most biologically. Typically, the less soluble diastere-. It washes away in the acidic water, leaving nearly pure phenylsuccinic acid as the solid.) A strong acid (6 M HCI), added in excess to the salt, is poorly soluble in water. 4, 279 (1987). Experts are tested by Chegg as specialists in their subject area. The pathway avoids the decarboxylation steps of the TCA cycle via the enzyme isocitrate lyase which cleaves isocitrate into succinate and glyoxylate. In order to recrystallize the solid, boiling water was added to the solid until it fully dissolves to achieve a complete homoge-nous mixture. Chirality is a necessary condition for the existence of optical activity (the ability to cause rotation, of the plane of polarized light). M. Yoshimura, M. Miyake, T. Kawato, et al., Cryst. 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 solid that results is now-resolved phenylsuccinic acid in its protonated form. [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. [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. Insoluble in water. Use a Pasteur pipet to drizzle 1-2 mL of ice-cold water over the entire surface of the solid to wash away as much 6 M HCl as possible. To purify, recrystallize the (S)-phenylsuccinic acid precipitate from water. The proline, its former partner in the salt, remains soluble in the aqueous phase. The phenylsuccinic acid is a proton donor making proline the proton acceptor. Abstract A new co-crystal compound of 4,4'-bipyridine and phenylsuccinic acid was synthesized and characterized by elemental analysis, infrared and ultraviolet-visible spectroscopy, and X-ray single crystal diffraction. In addition to its metabolic roles, succinate serves as an intracellular and extracellular signaling molecule. [citation needed], As a food additive and dietary supplement, succinic acid is generally recognized as safe by the U.S. Food and Drug Administration.

[14] Succinate can be used to derive 1,4-butanediol, maleic anhydride, succinimide, 2-pyrrolidinone and tetrahydrofuran. Cover the beaker or the vial with a watch glass, and keep the beaker covered at all times unless you need to access its contents! Eng. On this Wikipedia the language links are at the top of the page across from the article title. 7, 4 (2007). Google Scholar. mix contents for 2 minutes and reflux for 30 minutes. Such mirror images represent different stereoisomers , they are different molecules. this experiment, a reflux reaction A suitable solvent is found by trial and error. The phenylsuccinic acid would bind to the proton (H+), where it loses its negative charge and becomes insoluble in water. RST is the consecutive number of the substance in the series ABC. Measure the specific rotation and determine the enantiomeric excess of the sample. The name derives from Latin succinum, meaning amber.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 . Since PHDs have an absolute requirement for molecular oxygen, this process is suppressed in hypoxia allowing HIF1 to escape destruction.
