Modifications of proteins by polyunsaturated fatty acid peroxidation products. (1/33)
The ability of unsaturated fatty acid methyl esters to modify amino acid residues in bovine serum albumin (BSA), glutamine synthetase, and insulin in the presence of a metal-catalyzed oxidation system [ascorbate/Fe(III)/O(2)] depends on the degree of unsaturation of the fatty acid. The fatty acid-dependent generation of carbonyl groups and loss of lysine residues increased in the order methyl linoleate < methyl linolenate < methyl arachidonate. The amounts of alkyl hydroperoxides, malondialdehyde, and a number of other aldehydes that accumulated when polyunsaturated fatty acids were oxidized in the presence of BSA were significantly lower than that observed in the absence of BSA. Direct treatment of proteins with various lipid hydroperoxides led to a slight increase in the formation of protein carbonyl derivatives, whereas treatment with the hydroperoxides together with Fe(II) led to a substantial increase in the formation of protein carbonyls. These results are consistent with the proposition that metal-catalyzed oxidation of polyunsaturated fatty acids can contribute to the generation of protein carbonyls by direct interaction of lipid oxidation products (alpha,beta-unsaturated aldehydes) with lysine residues (Michael addition reactions) and also by interactions with alkoxyl radicals obtained by Fe(II) cleavage of lipid hydroperoxides that are formed. In addition, saturated aldehydes derived from the polyunsaturated fatty acids likely react with lysine residues to form Schiff base adducts. (+info)Cryopreservation reduces the ability of hamster 2-cell embryos to regulate intracellular pH. (2/33)
Vitrification of hamster 2-cell embryos impairs the activity of both the Na(+)/H(+) antiporter and HCO(3)(-)/Cl(-) exchanger; the two transport proteins responsible for the regulation of intracellular pH (pHi). The activities of both the Na(+)/H(+) antiporter and HCO(3)(-)/Cl(-) exchanger were significantly reduced at 4 h following warming compared to freshly collected embryos. Normal levels of activity of both transporters were not restored until 6 h after warming. Thus, cryopreservation of cleavage stage hamster embryos has a detrimental effect on their ability to maintain intracellular ionic homeostasis. Impairment of these pHi regulatory proteins resulted in the pHi of embryos being significantly elevated from the control values of 1.2 to 7.35 for approximately 4 h after warming. In addition, an elevated pHi value significantly impaired oxidative metabolism. Therefore, the loss in developmental competence of embryos following cryopreservation may in part be explained by a reduced ability to regulate intracellular pH that results in perturbations in metabolism and disruption of energy production. (+info)Extracellular HCO(3)(-) dependence of electrogenic Na/HCO(3) cotransporters cloned from salamander and rat kidney. (3/33)
We studied the extracellular [HCOabstract (3) (-)] dependence of two renal clones of the electrogenic Na/HCO(3) cotransporter (NBC) heterologously expressed in Xenopus oocytes. We used microelectrodes to measure the change in membrane potential (DeltaV(m)) elicited by the NBC cloned from the kidney of the salamander Ambystoma tigrinum (akNBC) and by the NBC cloned from the kidney of rat (rkNBC). We used a two-electrode voltage clamp to measure the change in current (DeltaI) elicited by rkNBC. Briefly exposing an NBC-expressing oocyte to HCOabstract (3 )(-)/CO(2) (0.33-99 mM HCOabstract (3)(-), pH(o) 7.5) elicited an immediate, DIDS (4, 4-diisothiocyanatostilbene-2,2-disulfonic acid)-sensitive and Na(+)-dependent hyperpolarization (or outward current). In DeltaV(m) experiments, the apparent K(m ) for HCOabstract (3)(-) of akNBC (10. 6 mM) and rkNBC (10.8 mM) were similar. However, under voltage-clamp conditions, the apparent K(m) for HCOabstract (3)(-) of rkNBC was less (6.5 mM). Because it has been reported that SOabstract (3)(=)/HSO abstract (3)(-) stimulates Na/HCO(3 ) cotransport in renal membrane vesicles (a result that supports the existence of a COabstract (3)(=) binding site with which SOabstract (3)(=) interacts), we examined the effect of SOabstract (3)(=)/HSO abstract (3)(-) on rkNBC. In voltage-clamp studies, we found that neither 33 mM SOabstract (4)(=) nor 33 mM SOabstract (3) (=)/HSOabstract (3)(-) substantially affects the apparent K(m) for HCO abstract (3)(-). We also used microelectrodes to monitor intracellular pH (pH(i)) while exposing rkNBC-expressing oocytes to 3.3 mM HCOabstract (3 )(-)/0.5% CO(2). We found that SO abstract (3)(=)/HSOabstract (3 )(-) did not significantly affect the DIDS-sensitive component of the pH(i) recovery from the initial CO(2 )-induced acidification. We also monitored the rkNBC current while simultaneously varying [CO(2)](o), pH(o), and [COabstract (3)(=)](o) at a fixed [HCOabstract (3)(-)](o) of 33 mM. A Michaelis-Menten equation poorly fitted the data expressed as current versus [COabstract (3)(=)](o ). However, a pH titration curve nicely fitted the data expressed as current versus pH(o). Thus, rkNBC expressed in Xenopus oocytes does not appear to interact with SOabstract (3 )(=), HSOabstract (3)(-), or COabstract (3)(=). (+info)The effect of feeding on the respiratory activity of the sloth. (4/33)
The aim of the present study was to confirm whether feeding influences the resting breathing rate and to observe possible alterations in blood gas and pH levels produced by feeding in unanesthetized sloths (Bradypus variegatus). Five adult male sloths (4.1 +/- 0.6 kg) were placed daily in an experimental chair for a period of at least 4 h for sitting adaptation. Five measurements were made for each sloth. However, the sloths one, two and five were studied once and the sloths three and four were studied twice. Breathing rate was determined with an impedance meter and the output signal was digitized. Arterial blood samples were collected for blood gas analysis with a BGE electrolytes analyzer and adjusted for the animal's body temperature and hemoglobin content. The data are reported as mean +/- SD and were collected during the resting period (8:00-10:00 h) and during the feeding period (16:00-18:00 h). The mean breathing rate increased during mastication of ymbahuba leaves (rest: 5.0 +/- 1, feeding: 10 +/- 1 bpm). No significant alterations were observed in arterial pH (rest: 7.42 +/- 0.05, feeding: 7.45 +/- 0.03), PCO2 (rest: 35.2 +/- 5.3, feeding: 33.3 +/- 4.4 mmHg) or PO2 (rest: 77.5 +/- 8.2, feeding: 78.4 +/- 5.2 mmHg) levels. These results indicate that in unanesthetized sloths 1) feeding evokes an increase in breathing rate without a significant change in arterial pH, PCO2 or PO2 levels, and 2) the increase in breathing rate produced by feeding probably is due to the act of mastication. (+info)Foraminiferal calcification response to glacial-interglacial changes in atmospheric CO2. (5/33)
A record of foraminiferal shell weight across glacial-interglacial Termination I shows a response related to seawater carbonate ion concentration and allows reconstruction of a record of carbon dioxide in surface seawater that matches the atmospheric record. The results support suggestions that higher atmospheric carbon dioxide directly affects marine calcification, an effect that may be of global importance to past and future changes in atmospheric CO2. The process provides negative feedback to the influence of marine calcification on atmospheric carbon dioxide and is of practical importance to the application of paleoceanographic proxies. (+info)Carbon dioxide combining properties of the blood of the shore crab Carcinus maenas (L): carbon dioxide solubility coefficient and carbonic acid dissociation constants. (6/33)
The carbon dioxide solubility coefficient, alphaCO2, and the apparent carbonic acid dissociation constants, K'1 and K'2 were estimated in the serum of the crab Carcinus maenas at various temperatures and ionic strengths. At 15 degrees C, the indirectly determined alphaCO2 value is 0-0499 m-mole l-1 torr-1 for crabs living in normal sea water (salinity ca. 35 percent). It is apparently independent of the serum protein concentration and of the stage of the moulting cycle. For crabs living in undiluted sea water, the mean pK'1 value, determined either gasometrically or titrimetrically, is 6-027 at 15 degrees C. At the same temperature, pK'2=9-29. These values approximate to those of sea water at 35 percent salinity. pK'1 drops as temperature rises; the measured deltapK'1/deltat is -0-0053 pH unit degrees C-1 between 10 and 30 degrees C. PK'1 rises as the ionic strength is lowered. Alignment nomograms have been constructed for the determination of alphaCO2, pK'1 and pK'2 values in relation to various conditions of temperature and salinity. (+info)Oxidized tissue proteins after intestinal reperfusion injury in rats. (7/33)
PURPOSE: To analyse if the carbonyl proteins measurement could be validated as a method that allows the identification of an intestinal oxidative stress after ischemia and reperfusion injury. METHODS: Twenty-five male Wistar rats (n = 21) weighting 200 to 250 g were divided into three groups. Group I--control (n = 10). Group II--sham (n = 5) and Group III (n = 10) subjected to 60 minutes of intestinal ischemia and equal period of reperfusion. For this purpose it was clamped the superior mesenteric artery in its distal third. Histological changes and carbonyl protein levels were determined in the samples of all groups. In group III, samples of both normal and reperfused ileal segment were studied. RESULTS: All the reperfused segments showed mucosal and submucosal swelling and inflammatory infiltrate of the lamina propria. Levels of carbonyl protein rose in group III, including in the non-ischemic segments. The sensitivity and specificity of the carbonyl protein tissue levels were respectively 94% and 88%. CONCLUSION: The carbonyl protein method is a useful biologic marker of oxidative stress after the phenomenon of intestinal ischemia and reperfusion in rats. It was also noteworthy that the effects of oxidative stress could be seen far from the locus of the primary injury. (+info)Isolation and characterization of a novel uronic acid-containing acidic glycosphingolipid from the ascidian Halocynthia roretzi. (8/33)
A novel uronic acid-containing glycosphingolipid (UGL-1) was isolated from the ascidian Halocynthia roretzi. UGL-1 was prepared from chloroform-methanol extracts and purified by the use of successive column chromatography on DEAE-Sephadex, Florisil, and Iatrobeads. Chemical structural analysis was performed using methylation analysis, gas chromatography, gas chromatography-mass spectrometry, matrix-assisted laser-desorption/ionization time-of-flight mass spectrometry, and 1H-NMR spectra. The chemical structure of UGL-1 was determined to be a glucuronic acid-containing glycosphingolipid, Galbeta1-4(Fucalpha1-3)GlcAbeta1-1Cer. The ceramide component was composed of C16:0 and C18:0 acids and C16-, C17-, and C18-phytosphingosines as major components. (+info)

Carbon Dioxide and Water1
- The basis of this rate enhancement is reaction between carbon dioxide and water to yield carbonic acid, which subsequently dissociates to increase the hydronium ion concentration above that of water alone. (elsevier.com)
Ions5
- Most commonly, the substance that absorbs the ions is either a weak acid, which takes up hydroxyl ions, or a weak base, which takes up hydrogen ions. (oregonstate.education)
- The kidneys help control acid-base balance by excreting hydrogen ions and generating bicarbonate that helps maintain blood plasma pH within a normal range. (oregonstate.education)
- Acids and bases are still present, but they hold onto the ions. (oregonstate.education)
- Aqueous buffer solutions will react with strong acids or strong bases by absorbing excess hydrogen H + ions, or hydroxide OH − ions, replacing the strong acids and bases with weak acids and weak bases . (readtiger.com)
- Similarly an excess of H + ions is partially neutralized by the bicarbonate component of the buffer solution to form carbonic acid (H 2 CO 3 ), which, because it is a weak acid, remains largely in the undissociated form, releasing far fewer H + ions into the solution than the original strong acid would have done. (readtiger.com)
Carbonate2
- It is a weak acid and it forms carbonate and bicarbonate salts. (byjus.com)
- Most of this carbon is in the form of bicarbonate with smaller amounts carbonate and carbonic acid. (sciencenotes.org)
Reaction2
- We report, for the first time, the acceleration of acid-catalyzed reactions in high-temperature liquid water by the addition of carbon dioxide to the reaction medium. (elsevier.com)
- These results demonstrate the feasibility of using CO 2 -H 2 O mixtures as an environmentally benign reaction medium for acid catalysis. (elsevier.com)
Conjugate base4
- The conjugate base corresponding to carbonic acid is the bicarbonate. (byjus.com)
- This is because they operate by making changes to the buffers, each of which consists of two components: a weak acid and its conjugate base . (readtiger.com)
- It is the ratio concentration of the weak acid to its conjugate base that determines the pH of the solution. (readtiger.com)
- Thus, by manipulating firstly the concentration of the weak acid, and secondly that of its conjugate base, the pH of the extracellular fluid (ECF) can be adjusted very accurately to the correct value. (readtiger.com)
Aqueous1
- It is not exerted by the chief mass of the air, but in a high degree by aqueous vapour and carbonic acid, which are present in the air in small quantities. (lemoyne.edu)
Esters1

- To attempt this experiment, you'll need some purple cabbage indicator water, which changes colors when acids and bases are added to it. (ehow.com)
- In several days, you will see that the water has changed colors because the exhaled carbon dioxide has combined with the water to create carbonic acid. (ehow.com)
- Carbonated water releases CO 2 bubbles for many minutes after pressure is released (dissolved carbonic acid reforming), which is an important presentation effect that other gases do not generally have. (stackexchange.com)
- The addition of weak acids to water helps with neutralising this effect. (stackexchange.com)
- Alkalinity is a measure of the acid-neutralizing capacity of water. (ufl.edu)
- The dissolved CO 2(aq) reacts with water molecules to form carbonic acid (H 2 CO 3 *), which is very unstable and quickly dissociates, yielding H + and a bicarbonate ion (HCO 3 - ) (Equations 2 and 3). (ufl.edu)
- When Na 2 HPO4 2− (the weak acid) comes into contact with a strong base, such as sodium hydroxide (NaOH), the weak acid reverts back to the weak base and produces water. (oregonstate.education)
- The enzymatic conversion of starch to sugar proceeds more readily in an alkaline environment(high PH).The conversion of sugar to starch occurs more readily in an acidic environment (low Ph).During the night, when photosynthesis is not taking place, carbon dioxide accumulates in leaf cells it combines with water to form carbonic acid.
