These samples were combined with 100 μl 40S subunits (100 OD260 U/ml) in buffer M. Proteins were extracted from these mixtures with 100 mM MgCl2 in 67% acetic acid and precipitated with 6.5 volumes acetone (Hardy et al., 1969), resuspended in 40 μl of 8 M urea, 1% 2-mercaptoethanol, 10 mM Bis-Tris acetate, pH 4.2, incubated for 15 min at 37°, and subjected to first dimension electrophoresis (Yusupov and Spirin, 1988) in 120-mm long glass tubes with a 2.4-mm inner diameter. Potassium acetate is the salt that forms along with water as acetic acid and potassium hydroxide are neutralized together. 1000 mM. The fumarate standard solution should be stored frozen and in this state it is stable for months. does not trigger action potentials when ECl is more negative than Vthreshold. Transfer the supernatant to a fresh tube, taking care not to transfer any of the precipitated solids. Remember that both of the reactants are aqueous, meaning, they are dissolved in water. Formula and structure: Potassium acetate chemical formula is CH 3 COOK and it molar mass is 98.14 g mol -1. CAS Number: 1515-76-0. pricing. Peak 48S fractions containing equal amounts of counts (∼200,000 cpm) are irradiated at 365 nm for 30 min on ice in quartz cuvettes (1-mm path length) and used to identify cross-linked nucleotides in 18S rRNA and cross-linked proteins. Neutralization of the alkaline conditions created by the lysis buffer establishes an environment in which hydrogen bonds can reform, allowing the small, single strands of your plasmid DNA to reanneal. Problem #11: Write the complete ionic and net ionic equation for this reaction in aqueous solution: AgNO 3 + CH 3 COOH ---> AgCH 3 COO + HNO 3. The positions of RT stop sites at AA1818–1819 are indicated on the right. Sodium acetate is a sodium salt of ethanoic acid (acetic acid) and contains two carbon atoms, 3 hydrogen atoms, 1 sodium atom, and 2 oxygen atoms. To characterize these interactions at nucleotide resolution, we designed vectors for transcription of mRNAs that incorporate 4-thiouridine (4SU) or 6-thioguanosine (6SG) residues (Fig. Adjust the pH to 5.5 with glacial acetic acid. These antibodies were efficient in immunoprecipitating in vitro translated μ. A resting membrane potential for the neuron of −60 mV and a threshold for action potential generation at −40 mV are assumed. Prolonged ER stress and absence of XBP-1 promote μ chain mislocalization in plasmablasts. Moreover, these μ chains were susceptible to trypsin digestion in permeabilized cells, further supporting an aborted insertion of μ chain into the ER upon prolonged treatment with proteasome inhibitor. After characterizing the cellular response, we carefully advanced the glass micropipette toward the recorded neuron until the spike amplitude (positive potential) became more than 1 mV. Do not freeze the cells as this will lyse a portion of them and will contaminate the sample. Interested readers are referred to the original publication (Yusupov and Spirin, 1988). It must not be administered undiluted. To attribute the cross-linked band to a particular ribosomal protein (Fig. Potassium chloride (also known as Sylvite, KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine.It is odorless and has a white or colorless vitreous crystal appearance. [9], Potassium acetate was incorrectly used in place of potassium chloride when putting a prisoner to death in Oklahoma in January 2015. K3PO4. C2H3O2^-Carbonate . To neutralize the pH and precipitate some contaminants, neutralization buffer is then added to the tube. Molecular Weight: 98.14. Acetate is a monocarboxylic acid anion resulting from the removal of a proton from the carboxy group of acetic acid. The molecule is formed by one potassium cation K + and one acetate anion CH 3 COO -. Before you do anything, you are going to need 4 lines to do this. Please include state symbols in both reactions. Ammonium fluoride. It is a substitute for chloride salts such as calcium chloride or magnesium chloride in deicing applications. The gradients are fractionated into ∼25 fractions, and the presence of [32P]-labeled mRNA in ribosomal fractions is monitored by Cherenkov counting. VASILE V. COSOFRET, in Membrane Electrodes in Drug-Substances Analysis, 1982. [11], Potassium acetate is used as a catalyst in the production of polyurethanes.[12]. In medicine, potassium acetate is used as part of replacement protocols in the treatment of diabetic ketoacidosis because of its ability to break down into bicarbonate and help neutralize the acidotic state. 10 mM. For patients without significant acid-base abnormalities, the ratio of chloride to acetate administered is generally kept at 1:1. The permeabilization occurs very fast. #"CH"_ 3"COONa"_ ((aq)) -> "CH"_ 3"COO"_ ((aq))^(-) + "Na"_ ((aq))^(+)# When the hydrogen is lost, acetate ion (CH3CO2-) is formed. This inhibitory effect of GABA is called a shunting effect. Ph.D, in RNA Methodologies (Fourth Edition), 2010. When ECl is more depolarized than Vrest, the activation of GABAA receptors causes an inward current (outward flow of Cl− ions) and a depolarization of the membrane. Potassium acetate is used in mixtures applied for tissue preservation, fixation, and mummification. Cross-linked and uncross-linked 18S rRNA fragments generated by RNAse H treatment were visualized by autoradiography and methylene blue staining, respectively (Fig. Incubate supernatant on ice for an additional 15 min. The acetate ion is completely metabolized in the body, providing a source of hydrogen ion acceptors. Potassium phosphate. Inclusion of additional U or G nucleotides in these mRNAs was avoided by flanking AUG codons with multiple CAA triplets, which also minimize secondary structure and which we have previously found to yield highly efficient templates for assembly of initiation complexes (Pestova and Kolupaeva, 2002). 1997), but we determined that 6SG -containing mRNAs are functional (Pisarev et al., 2006). A final wash with 95–100% ethanol will accelerate the drying process. In a control reaction, UV cross-linking was done with 48S complexes assembled on (CAA)n–AUG–(CAA)m mRNA derivatives containing 6SG at [-3]. The position corresponding to the radioactive spot (E) is shown as a black oval on the stained gel (D). 2021-01-02. In molecular biology, potassium acetate is used to precipitate dodecyl sulfate (DS) and DS-bound proteins, allowing the removal of proteins from DNA. 7.5D) and were either dried and autoradiographed (Fig. Centrifuge at 10,000×g for 10 min. We recommend using the minimal concentration that yields 95% of trypan blue positive cells. The concentration of trypsin should also be adjusted according to the sensitivity and abundance of the protein. For patients with a metabolic acidosis, the acetate in the parenteral nutrition solution should be maximized to increase the amount of bicarbonate produced. The table shows the names and formulae of some common ions. For potassium chloride a determination of chloride is recommended (Section 5.1). The easiest way is by using a heat gun. Also known as: Potassium salt, E261, KCH3COO, CH3COOK 1 mM. Further, this substance is deliquescent. 0.1N. CO3^2-40 Terms. The chemical and molecular formula for sodium acetate is written as-. Robert E. FarrellJr. CAS Number: 127-08-2 (B) Sequences of (CAA)n–AUG–(CAA)m mRNA derivatives containing 4SU or 6SG at -3 or +4 positions (bold) relative to the A of the initiation codon (underlined). The solution is intended as an … 4H2O in distilled water and make up to 100 ml. 6SG is incorporated less efficiently into RNA than 4SU and has an absorption maximum of ∼310 nm (instead of ∼330 nm for 4SU) so that its efficiency of cross-linking at 365 nm is considerably lower than that of 4SU. The solid dissolves readily in water, and its solutions have a salt-like taste.Potassium chloride can be obtained from ancient dried lake deposits. List of Potassium Compounds, Common Compounds of Potassium K, Formula, Molecular Weight We use cookies to help provide and enhance our service and tailor content and ads. Potassium Acetate Injection, USP, is indicated in the treatment of potassium deficiency states when oral replacement therapy is not feasible. Identification of sites of cross-linking of individual 4SU or 6SG nucleotides in 32P-labeled mRNAs to 18S rRNA can be done in two stages (Dontsova et al., 1992). Kensaku Mori, in Axons and Brain Architecture, 2016. It has a faint acetic smell. These 48S complexes are resolved from unincorporated components by centrifugation in a Beckman SW55 rotor for 1 h and 40 min at 4° and 50,000 rpm in 10 to 30% sucrose density gradients prepared in buffer J. It has the chemical formula CH 3 COOK in which, K + is potassium cation and CH 3 COO – is acetate anion. Ammonium sulfate. hwhamilton. All cross-linked peak fractions (∼200 μl each) were combined, transferred to buffer M, and concentrated on microcon-YM10 centrifugal filter units to 100 μl final volume, and treated with 50 μg RNase A for 30 min at 37°. mRNA transcripts were separated from unincorporated components by use of Sephadex G-50 Spin-50 mini-columns. It must be noted that this shunting effect of GABA is always present, whatever the effect of GABA (hyperpolarization, silence or depolarization), and it attenuates other concomitant depolarizations or hyperpolarization. Prepare 3 M potassium acetate (KCH3O2) in 80% of final volume. PBS, KH buffer (100 mM potassium acetate, 20 mM HEPES, pH = 7.2), Digitonin (Roche), MG132 (proteasome inhibitor provided by multiple suppliers). 7.5G). (D) wt B cells, pretreated with MG132 for 6 h, were permeabilized using 0.008% digitonin, and subjected to trypsin digestion at 4 oC (lanes 3 and 4). 7.5F). By continuing you agree to the use of cookies. Completely remove supernatant. A reasonable range is 0.004–0.025%. 4SU has several properties that render it particularly appropriate for this purpose: it can be readily incorporated into mRNA transcripts by T7 RNA polymerase; it engages in conventional base-pairing interactions; it can be selectively activated at wavelengths (330 to 370 nm) that minimize side reactions involving other nucleotides in mRNA, tRNA, and rRNA; and, importantly, it is highly photoreactive with both amino acid residues and nucleic acid bases, yielding “zero-length” cross-links that represent direct contacts with 48S complex constituents and that can, therefore, be analyzed with high precision. Calcium nitrate. These transcripts initiated from A to avoid the presence of a 5′-terminal guanosine, but because transcription by T7 RNA polymerase initiates less efficiently from A than G at the +1 position, 100-μl transcription mixtures were supplemented with 1 mM rAC transcription primer to increase initiation efficiency. Therefore, the kidney normally determines potassium balance. Linear Formula: CH2=CHCH=CHOCOCH3. 1)Sodium acetate formula CH₃COONa 2) Potassium acetate formula CH₃COOK [7] Potassium hydrogen diacetate (CAS #4251-29-0 ) with formula KH(OOCCH3)2 is a related food additive with the same E number as potassium acetate. Synonym: 1,3-Butadienyl acetate. We hypothesized that the role of -3 and +4 context nucleotides could be to stabilize conformational changes in ribosomal complexes that occur on codon-anticodon base pairing by interacting with components of these complexes. Most cross-linked initiation factors and their subunits can be identified by autoradiography on the basis of the electrophoretic mobility in NuPAGE 4 to 12% Bis-Tris-gel of cross-linked proteins from RNAase-digested fractions (Fig. Their concentration is much higher within the cells than in the extra-cellular fluid, and there is an uptake of potassium during glycogen storage. (G) Determination of the exact sites of cross-linking of (CAA)n–AUG–(CAA)m mRNA derivatives containing 6SG at [+4] to 18S rRNA in 48S complexes by primer extension analysis. Adi Drori, Boaz Tirosh, in Methods in Enzymology, 2011. [10] In August 2017, the U.S. state of Florida executed Mark James Asay using a combination of etomidate, rocuronium bromide, and potassium acetate. Deficiency of potassium ions causes acute muscular weakness, paraesthesia and cardiac arrhythmias. Sigma-Aldrich. Writing formulas for ionic compounds with polyatomic ions. Calcium nitrate. In our case, acidic-SDS 2D gel was appropriate; however, the choice of the first dimension (acidic versus basic) depends on the nature of the cross-linked proteins and must be empirically determined if the nature of the cross-linked proteins is unknown. Terminate the reaction by adding 5 mg/ml of soybean trypsin inhibitor. When ECl is more depolarized than the threshold for activation of voltage-dependent Na+ channels, GABAA receptor activation causes a postsynaptic depolarization or EPSP and evokes spikes. The melting point is 292 °C, and upon further heating, the compound will decompose. For example, Lenin's mummy was soaked in a bath containing potassium acetate. The interaction of mRNA with ribosome and initiation factor components of preinitiation and initiation complexes likely plays specific roles in ensuring processivity during scanning, in initiation codon selection, and in ensuring the stability of assembled complexes. Only when the cells were treated for 6 h with proteasome inhibitor prior to the pulse-labeling a second polypeptide was seen. Solution: 1) Complete ionic: Ag + (aq) + NO 3-(aq) + CH 3 COOH(aq) ---> AgCH 3 COO(s) + H + (aq) + NO 3-(aq) . Potassium acetate, also known as potassium salt E261, is a salt used in the pharmaceutical and food industries as an additive. Create . 6SG exists in a thiol–thione equilibrium that could potentially lead to misincorporation during transcription (Favre et al., 1998; Sergiev et al. It is far better to leave a small amount of supernatant behind than to risk carryover of cell debris. INDICATIONS. To deduce the formulae of ionic compounds, the formulae of their ions can be used. If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. Chemical formula: C 2 H 3 KO 2. Login to create quizzes If you are not registered user register here to login The cross-linked nucleotide is then identified precisely by primer extension with a primer chosen on the basis of preliminary identification of the cross-linked region by RNAse H digestion. In this case, GABAA current adds to other depolarizing current flowing through the membrane but once Vm becomes more depolarized than ECl, the GABAA current becomes hyperpolarizing. Figure 9.17. Dissolve the digitonin by heating it to boiling. In Fig. After the recording of odor responses, neurons were electroporated to inject BDA by passage of positive current pulses (0.5–1.5 nA; 400 ms duration; 50% duty cycle) through the bridge circuit of the amplifier (Figure 1.9C). 17.3, we demonstrate ER mislocalization of μ chains in LPS-activated B cells. with distilled water. Your double-stranded plasmid DNA will now easily dissolve in solution while the long stretches of bacterial genomic DNA will be unable to reanneal and dissolve. We will illustrate the application of this technique by describing our studies on identification of specific functional interactions of the -3 and +4 context nucleotides with components of the 48S complex (Pisarev et al., 2006). It is insoluble … (D) A gel of 40S subunit proteins stained with Simply Blue Safe Stain and (E) an autoradiograph of the same gel.

KH2PO4 adjusted with 0.1 N KOH to pH 6 and diluted with distilled water to 1000 ml.). When ECl is close to Vrest, the electrochemical gradient for Cl− is very weak or null and no IPSP is observed even though GABAA channels are open. Potassium Acetate ( KC2H3O2 ) is Ionic I'll tell you the ionic or Covalent bond list below. NH4F. 2D gel electrophoresis might also be required for identification of the small eIF3k subunit of eIF3 (which comigrates with ribosomal proteins) and to distinguish the closely migrating eIF3 subunits eIF3e–eIF3h. 7.5D,E), the so-called north–west shift of a cross-linked protein caused by the presence of cross-linked nucleotides must be taken into account. 7.5A) at single unique positions (in addition to the initiation codon) that can subsequently be selectively cross-linked to adjacent proteins and nucleic acids. Laura Koontz, in Methods in Enzymology, 2013. If a protein band appears between the upper and lower phases, repeat the extraction with a fresh aliquot of chloroform:isoamyl alcohol (24:1). Harvest bacterial cells from a 100 ml culture by centrifugation. Store sample at –20° for 20 min to precipitate the RNA. The acetate buffer keeps in a refrigerator for several months. First, determine the minimal concentration of digitonin needed for efficient permeabilization. Reversal potential of GABAA-mediated IPSPs as a function of membrane potential. back to Kinetics and Equilibrium links . Be sure to use centrifuge tubes rated for this g-force. Use in executions Place the cells on ice and add digitonin. Site-directed UV cross-linking of mRNA in ribosomal initiation complexes. Allow the sample to air-dry, and then resuspend in TE buffer or nuclease-free H2O. To determine the working dilution of the digitonin wash the cells in PBS and resuspend them in permeabilization buffer (KH buffer, see recipe above). Cheng Wu, Matthew S.

On the other hand, the identification of ribosomal proteins, which are similar in molecular weight, requires two-dimensional (2D) gel electrophoresis. Furthermore, we … Potassium acetate is used as a diuretic and urinary alkaliser and acts by changing the physical properties of the body fluids and by functioning as an alkali after absorption. Molecular Weight: 112.13. Lee-lynn Chen MD, Annette Stralovich-Romani RD, CNSD, in Critical Care Secrets (Fourth Edition), 2007. Carbonate. Cells were lysed in NP-40 lysis buffer. Chemistry Formulas: Chemistry Formulas. Centrifuge for 3 min to separate the phases. The firing of the recorded neuron was continuously monitored during and after the current injection to ensure that the neuron was steadily held throughout the session. Mix carefully and thoroughly. It may be helpful to divide the lysate into several microcentrifuge tubes so that the investigator always has access to several aliquots of RNA made from the same culture on the same day. Potassium acetate is used as a food additive as a preservative and acidity regulator. To investigate the interactions of the -3 and +4 context nucleotides with components of the 48S complex, we used mRNAs of the [CAA]n-AUG-[CAA]m series that contained a single uridine or guanosine (in addition to the AUG codon; Fig. Add 100 g guanidinium thiocyanate (GTC) per 100 ml. Sodium Acetate Injection, USP (2 mEq/mL) is a sterile, nonpyrogenic, concentrated solution of Sodium Acetate in water for injection. Read the rules, watch the video, then practice it a few times and it is really not that bad. Potassium acetate was originally used in the preparation of Cadet's fuming liquid, the first organometallic compound produced. Acetate is metabolized to bicarbonate. 220868. mixture of cis and trans. It is also used as a salt for the ethanol precipitation of DNA. Transfer the upper aqueous phase to a fresh tube, and then add 0.6 volume of ice-cold isopropanol. In the cases of successful electroporation of BDA, the applied positive currents induced burst discharges of the recorded neuron only during the current injection (Figure 1.9C). Formula: Potassium acetate: C 2 H 3 KO 2 (MM = 98.14) CH 3 COOk: Potassium chloride: KC1 (MM = 74.56) Potassium gluconate: C 6 H 11 KO 7 (MM = 234.3) HOCH 2 CH(OH) 4 COOK: Category: Potassium ions play an important part in cellular metabolism.

Potassium acetate is KC2H3O2. 7.5B). Most museums today use the formaldehyde-based method recommended by Kaiserling in 1897 which contains potassium acetate. First dimension gels were incubated for 10 min in cathode buffer and combined with second dimension gels prepared as described in detail elsewhere (Schagger and von Jagow, 1987). After determination of RNA concentration and purity, store in suitable aliquots at –80°. Cross-linked nucleotides are then located precisely in 18S rRNA by primer extension inhibition in a 20 μl reaction mixture containing 2-μl aliquots of resuspended cross-linked 18S rRNA, 1 μg of oligodeoxyribonucleotide complementary to a region of 18S rRNA (chosen on the basis of preliminary mapping by RNase H digestion), and 5 U AMV RT. It is also useful as an additive for preparing specific intravenous fluid formulas when the needs of the patient cannot be met by standard electrolyte or nutrient solutions. The Chemical Formula for Potassium Acetate is CH3CO2K which shows that it has 4 types of atoms in it: 2 Carbon, 3 Hydrogen, 2 Oxygen, and 1 Potassium. Homogenize 100 mg. lyophilized cells (see p.349) in 1 ml. 7.5C). Allow lysate to incubate on ice for 10 min. More... Molecular Weight: 59.04 g/mol. To avoid this potential problem, another sucrose density gradient centrifugation separation step must be performed after cross-linking if interaction of mRNA with RNA-binding factors (e.g., eIF3) is being studied. However, this is not always the case. Copyright © 2021 Elsevier B.V. or its licensors or contributors. For patients with a metabolic alkalosis, the acetate can be minimized to decrease the amount of bicarbonate produced. The molecular or chemical formula of Potassium Acetate is C 2 H 3 KO 2. 18S rRNA was digested in the presence of a DNA primer complementary to nucleotides 1652 to 1683 and analyzed by electrophoresis in denaturing 12% PAGE with subsequent staining (left panel) or autoradiography (right panel). Molecular Formula: CH 3 COO(−) or C 2 H 3 O 2 (−) or C 2 H 3 O 2-Synonyms: acetate. This solution contains a high concentration of potassium acetate, pH 5.5, which is in equilibrium with acetic acid and K+. Total cell lysates were immunoprecipitated with the commercial polyclonal anti-μ antibody as well as with anti-GS4 and anti-GS5. The solution contains no bacteriostat, antimicrobial agent or added buffer. 18S rRNA UV cross-linked to a 32P-labeled (CAA)n–AUG–(CAA)m mRNA derivative containing 4SU at the [+4] position in 48S complexes assembled with a full set of initiation factors. The potassium ion from the potassium acetate creates a high-salt environment, which precipitates the cellular debris, the single-stranded genomic DNA, and the SDS (as KDS, the white precipitate that forms in your tube). It is, however, more expensive. It should be noted that a small proportion of 48S complexes can dissociate during the cross-linking procedure and that the released mRNA can rebind nonspecifically to RNA-binding initiation factors that are components of 48S complexes (e. g., several subunits of eIF3), which can lead to false-positive cross-links. Single-cell labeling of individual functionally identified neurons was performed using the juxtacellular electroporation technique (Pinault, 1996). Identification of cross-linked regions and their attribution to corresponding uncross-linked fragments of 18S rRNA on stained gels is done, taking into account the reduced mobility of cross-linked rRNA fragments because of the covalently bound mRNA (Fig. CH 3 COONa. μ chains were immunoprecipitated using a mixture of anti-GS4/anti-GS5 to increase avidity, or goat α-IgM, as indicated. Action potentials are truncated owing to their large amplitude. Wash the pellet with 1.5 ml of ice-cold PBS. The separating gel (16.5% T (total monomer concentration) and 3% C (weight percentage of cross-linker) also contained 13.3% w/v glycerol. We reason that under these conditions the defect in ER insertion is most likely general. (F) Preliminary mapping of the site of cross-linking to 18S rRNA by RNase H digestion. The reaction mixture is incubated for 30 min at 37°, and cDNA products are analyzed by electrophoresis through 7 M urea/6% polyacrylamide sequencing gel (Fig. Each mL contains 164 mg of Sodium Acetate (anhydrous) which provides 2 mEq each of sodium (Na+) and acetate (CH3COO-). It is due to an increase in the membrane conductance (GIPSP) during the silent inhibition owing to the opening of GABAA channels. Once boiled, leave the solution to cool at room temperature, then store at 4 °C. Over time a whitish precipitate will appear in the tube. Andrey V. Pisarev, ... Tatyana V. Pestova, in Methods in Enzymology, 2007. For m chains 0.5 μg/ml was sufficient. The solution is administered after dilution by the intravenous route as an electrolyte replenisher. K3PO4 (NH4)2SO4. Scanning 40S subunits can bypass the first AUG triplet if it is <10 nucleotides (nt) from the 5′ end of mRNA or if its context deviates from the optimum sequence GCC(A/G)CCAUGG, particularly at -3 and +4 positions (in bold) (Kozak, 1986, 1991). Resuspend 3 × 106 cells in 200 μl of KH buffer containing 0.008% digitonin, supplemented with 10 μM MG132. We generated monoclonal antibodies directed against the glycosylation site 4 and 5 of μ chains (termed anti-GS4 and anti-GS5, respectively). [8] For example, Lenin's mummy was soaked in a bath containing potassium acetate. An estimated daily turnover of the acetate ion in humans is about 45 g day −1. It is estimated that the plasma level of the acetate ion in humans is about 50–60 μmol l −1 (3.0–3.6 mg l −1) and 116 μmol l −1 (7 mg l −1) in cerebrospinal fluid. (2006) with permission (Copyright © Cold Spring Harbor Laboratory Press, Genes and Development 20, 624-636-2797 [2006]). Acetic acid is a weak acid, consequently it is written in molecular form. (C) wt B cells were treated with MG132 for 6 h and lysed using NP-40. Most museums today use the formaldehyde-based method recommended by Kaiserling in 1897 which contains potassium acetate. Combine 1.5 ml of ice-cold lysis buffer with 2 ml ice-cold potassium acetate buffer, above, and then gently resuspend the cell pellet in this mixture. Interestingly, when mislocalization of μ was compared between XBP-1 KO and wt B cells, we observed reduced ER targeting in the KO cells. 5E) to determine the location of cross-linked proteins or used for in-gel tryptic digestion to generate peptides for LC-nanospray tandem mass spectrometry to confirm the identity of cross-linked proteins. Typical protocol for LPS-activated B cells: Use freshly pulse-labeled B cells as described above. This depolarization does not excite the membrane; i.e. Figure 01: Structure of Potassium Acetate.
