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. (If there is no precipitate, use a Pasteur pipet to remove about I mL to a small test tube. [39] Other inflammatory cytokines produced by activated macrophages such as tumor necrosis factor or interleukin 6 are not directly affected by succinate and HIF1. too much present in sample (soluble) Such mirror images represent different stereoisomers , they are different molecules. Share Improve this answer Follow edited Oct 28, 2019 at 15:24 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. This involves an acid-base reaction with (s)-proline and restor- >> Under pathological and physiological conditions, the malate-aspartate shuttle or the purine nucleotide shuttle can increase mitochondrial fumarate, which is then readily converted to succinate. [28], The activity of succinate dehydrogenase (SDH), which interconverts succinate into fumarate participates in mitochondrial reactive oxygen species (ROS) production by directing electron flow in the electron transport chain. [6][26] Extra-mitochondrial succinate alters the epigenetic landscape by inhibiting the family of 2-oxogluterate-dependent dioxygenases. so they can be created by reacting https://doi.org/10.1134/S1063774519070125, DOI: https://doi.org/10.1134/S1063774519070125.

You have the right to unsubscribe at any time by clicking the 'unsubscribe' link in any News & Announcement emails you receive. Dysregulation of succinate synthesis, and therefore ATP synthesis, happens in some genetic mitochondrial diseases, such as Leigh syndrome, and Melas syndrome, and degradation can lead to pathological conditions, such as malignant transformation, inflammation and tissue injury.[6][7][8]. behave identically toward physical tests like melting and boiling points and solubility in given solvents. 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! To get rid of 2-propanol and any unreacted phenylsuccinic acid, wash the crystals with 10 mL of acetone. The The first source was natural products chemicals produced by living organisms. [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. Oxidative decarboxylation then generates a ferryl intermediate coordinated to succinate, which serves to oxidize the bound primary substrate. The acid and base are structurally more complex than HCl and NH3, but the concept is the same. the proton acceptor. configuration enantiomer, the other diastereomer must be more soluble during the filtration For this reason, if the biologically produced. 32% (R) - 67% (S), To comprehend the conver- Vacuum filter and wash the solid with two 15mL volumes of cold water. Enantiomeric excess: 60.65171=0 100 =35% of (+)-phenylsuccinic acid [28], Succinate serves as a modulator of blood pressure by stimulating renin release in macula densa and juxtaglomerular apparatus cells via GPR91. This property is a direct consequence of the configuration, or orientation of bonded atoms in space, around the chiral center. .

All rights reserved. CAS Number: 635-51-8. 9, 1436 (2009). The toxicological properties of this material have [30], In adipocytes, the succinate-activated GPR91 signaling cascade inhibits lipolysis. Organic Chemistry I This is an ordinary acid-base reaction that produces a salt. [7][32] Succinate may enhance adaptive immunity by triggering the activity of antigen-presenting cells that, in turn, activate T-cells. On this Wikipedia the language links are at the top of the page across from the article title. Growth Des. acid into separable diastereomers. please email the information below to [emailprotected]. Don't use too much water, as the product is somewhat soluble and will slowly dissolve. RST is the consecutive number of the substance in the series ABC. [40] In spite of a general downregulation of the TCA cycle under these conditions, succinate concentration is increased. of this substance have not been fully investigated. Soluble in acetone, alcohols, and methanol. Since our excess is very low, our substance was nowhere near being pure. [8] ROS then trigger the cellular apoptotic machinery or induce oxidative damage to proteins, membranes, organelles etc. [26] As such, succinate links TCA cycle dysfunction or metabolic changes to cell-cell communication and to oxidative stress-related responses. [26] Alternative, succinate can be released into the extracellular milieu and the blood stream where it is recognized by target receptors. In this case, the salt that contains the dextrorotatory acid ("") is the less soluble one, and precipitates. Solubility: Not available. Santa Cruz Biotechnology, Inc. is a world leader in the development of products for the biomedical research market. A strong acid (6 M HCI), added in excess to the salt, is used to protonate the water-soluble anion. [12], In 2004, succinate was placed on the US Department of Energy's list of top 12 platform chemicals from biomass. G. M. Sheldrick, Acta Crystallogr. Succinic acid (/sksnk/) is a dicarboxylic acid with the chemical formula (CH2)2(CO2H)2.

Think of a chiral center as an atom to which four different, groups are covalently attached. <> M. R. Caira, Mol. Since PHDs have an absolute requirement for molecular oxygen, this process is suppressed in hypoxia allowing HIF1 to escape destruction. [7] For dendritic cells, succinate functions as a chemoattractant and increases their antigen-presenting function via receptor stimulated cytokine production. Molecular Formula: C 10 H 10 O 4. 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 is generated from succinyl-CoA by the enzyme succinyl-CoA synthetase in a GTP/ATP-producing step:[22]:Section 17.1, Succinyl-CoA + NDP + Pi Succinate + CoA + NTP, Catalyzed by the enzyme succinate dehydrogenase (SDH), succinate is subsequently oxidized to fumarate:[22]:Section 17.1, SDH also participates in the mitochondrial electron transport chain, where it is known as respiratory complex II. Pharm. 4 0 obj Molecular Formula: C 10 H 10 O 4. For Research Use Only. 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. Most often, these pieces can attach to the enzyme only in one particular, orientation. The phenylsuccinic acid is a proton donor making proline the proton acceptor. Growth Des. In addition to its metabolic roles, succinate serves as an intracellular and extracellular signaling 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. Two protons are transferred from the phenylsuccinic acid to the proline. Add 1.15g of finely ground (s)-proline & a magnetic stir bar then mix contents for 2 minutes and reflux for 30 minutes. [31] SDH mutations have also been identified in gastrointestinal stromal tumors, renal tumors, thyroid tumors, testicular seminomas and neuroblastomas. (2018). [6] It is marketed as food additive E363. Succinate can exit the mitochondrial matrix and function in the cytoplasm as well as the extracellular space, changing gene expression patterns, modulating epigenetic landscape or demonstrating hormone-like signaling. [11], Genetically engineered Escherichia coli and Saccharomyces cerevisiae are proposed for the commercial production via fermentation of glucose.
