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. 4036-30- (S)-(+)-Phenylsuccinic acid >99 223-719-3 Section 3 - Hazards Identification EMERGENCY OVERVIEW Appearance: almost white solid. Space available to draw mechanisms. A strong acid (6 M HCI), added in excess to the salt, is poorly soluble in water. [citation needed], As a food additive and dietary supplement, succinic acid is generally recognized as safe by the U.S. Food and Drug Administration. [30], SUCNR1 is highly expressed on immature dendritic cells, where succinate binding stimulates chemotaxis. [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. [32] The ligand specificity of GPR91 was rigorously tested using 800 pharmacologically active compounds and 200 carboxylic acid and succinate-like compounds, all of which demonstrated significantly lower binding affinity. 4 0 obj

Question: In this experiment, racemic (RS)-phenylsuccinic acid is separated (resolved) into optically active cautiouets in a sequence of two steps. For a compound to be optimally pure, it would have to reach up to 171. Exact concentration: 0 10 mL=0. A suitable solvent is found by trial and error. 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. 1112, 1 (2016). Typically, the less soluble diastere-. 17, 550 (2017). 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. N. J. Babu, L. S. Reddy, and A. Nangia, Mol. Note that the two diastercomeric salts (S.S) and (R.S) differ in their mions (phenylsuccinate), which are nonsuper-posable mirror images, but have identical cations (L-proline). This process [39] Other inflammatory cytokines produced by activated macrophages such as tumor necrosis factor or interleukin 6 are not directly affected by succinate and HIF1. This application requires Javascript. Rep. 64, 10381042 (2019).

To purify, recrystallize the (S)-phenylsuccinic acid precipitate from wa- The solubility of the complexes is poor in the top phase, where H 2 A has better solubility than in the bottom phase. The calculated specific rotation came out to be 60.65, meaning that it was not optimally pure but the fact that it was positive meaning that it was more of an S enan-tiomer than an R which was preferred. In this case, the salt that contains the dextrorotatory acid ("") is the less soluble one, and precipitates. Put the entire crude product into a small beaker or glass vial, and add approx. ABC corresponds to the atomic number of the most characteristic element or the most characteristic organic group in the molecule. * Refer to Certificate of Analysis for lot specific data (including water content).
