Taschenbuch. Condición: Neu. Neuware - Wolne rodniki s¿ produktami ubocznymi ró¿nych procesów fizjologicznych i odgrywaj¿ wän¿ rol¿ w szlakach metabolicznych, sygnalizacyjnych i rozwojowych. Zanieczyszczenia ¿rodowiska, palenie tytoniu, promieniowanie UV i ¿ywno¿¿ mog¿ równie¿ powodowä powstawanie wolnych rodników lub prooksydantów. Nadmierna produkcja wolnych rodników ma negatywny wp¿yw na organizmy ¿ywe i mo¿e powodowä stres oksydacyjny prowadz¿cy do rozleg¿ych uszkodze¿ komórek. Uszkodzenia oksydacyjne wywo¿ane przez wolne rodniki odgrywaj¿ wän¿ rol¿ w patogenezie chorób nowotworowych, neurodegeneracyjnych, metabolicznych, reprodukcyjnych i psychologicznych. Organizmy ¿ywe opracowäy skuteczne mechanizmy obronne przeciwdziäaj¿ce z¿emu dziäaniu wolnych rodników poprzez zastosowanie ró¿nych przeciwutleniaczy. Ksi¿¿ka ta przedstawia podstawowe procesy ¿yciowe podtrzymuj¿ce ¿ycie, rodzaje wolnych rodników, ich wytwarzanie oraz ich wp¿yw na biomoleku¿y i struktury komórkowe.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Zea mays (a C4 plant) can withstand high sulfur dioxide concentrations up to 12.0 ppm without any harmful effects. Visible injury symptoms appear only after exposure to sulfur dioxide concentrations beyond 12.0 ppm. The pigments,proteins,amino acids and starch decrease after exposure to higher concentrations of sulfur dioxide. The free sugars,however,increase in response to sulfur dioxide exposure. The activity of PEP - carboxylase is inhibited non -competitively with respect to substrates, PEP and Mg2+ but it is competitive with HCO3-.The high affinity of the enzyme for HCO3- renders the replacement by sulfur dioxide more difficult which results in decreased sensitivity towards sulfur dioxide. NADP - malate dehydrogenase is inhibited uncompetitively with respect to OAA and non competitively with respect to NADPH. The low inhibitory effect of sulfur dioxide on the enzymes is indicated by high Ki values.In case of NADP - malic enzyme,sulfur dioxide shows a non competitive inhibition with respect to NADP+ but a competitive one with respect to Mg2+. With respect to malate, the inhibition is partially competitive. 196 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Thymus serpyllum commonly known as Jawand in Kashmir is used as a culinary herb, as well as for aromatizing and traditional medicinal purposes. The word thyme is a general name for more than three hundred Thymus species, hybrids, varieties and ecotypes, all of which are small perennial herbs native to Europe and Asia. There are many traditions related to the tonic character of these plants. The Egyptians used it in embalmment. The Roman soldiers used to take a bath in water with thyme to provide vigour. Thyme oil was used as an antiseptic during World War I. Still today, thyme is used in the embalmment liquids, protects paper from mould, and is used to preserve anatomy and botany specimens. The present study confirmed that the plant Thymus serpyllum possesses significant in vitro antioxidant and antimicrobial activity and in vivo anti inflammatory activity. 112 pp. Englisch.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Proteinase inhibitors (PIs) are small proteins that are quite common in nature. PIs are present in multiple forms in numerous tissues of animals and plants as well as in microorganisms. Serine proteinase inhibitors are widespread in the plant kingdom. The present study was at investigating the biochemical properties of protease Lavatera cashmeriane seeds. Four protease inhibitors LC-pi I, LC-pi II, LC-pi III and LC-pi IV were purified from the seeds of Lavatera cashmeriane by ammonium sulphate precipitation and ion-exchange chromatography on DEAE-cellulose column. All were strong inhibitors of trypsin, chymotrypsin and elastase. The molecular weight of LC-pi I, LC-pi II, LC-pi III, and LC-pi IV was found to be 20.89, 14.12, 16.78 and 7.94kDa respectively by gel filtration chromatography and 10, 14, 16 and 7kDa respectively by SDS-PAGE. The SDS-PAGE revealed that LC-pi I is constituted of two subunits of 10,000 Da each. The optimum temperature for the inhibitors was found to be 30 C for all inhibitors. LC-pi I showed strong antibacterial activity against Klebsiella pnuemoniea, and Pseudomonas aeruginosa but was less active against E.coli.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware --galactosidases belong to glycosyl hydrolase family of enzymes.These enzymes are widely distributed in nature. -galactosidases have been implicated in many biological functions like hydrolysis of dietary lactose,degradation of glycolipids and proteoglycans,fruit ripening, cell elongation, storage mobilisation and petal senescence. - galactosidase has proven as a best alternative for elimination of lactose intolerance.The present study was aimed at investigating the biochemical properties of -galactosidases from apricots.Three isoenzymes( gal I, gal II and gal III) were obtained by salt fractionation and ion-exchange and Sephadex G-100 column chromatography. -gal I,II and III showed 0.39, 0.52 and 0.30 units of activity respectively. The molecular weight of gal I,II an III as determined by gel filtration was found to be 44.15,34.70 and 23.71 KDa respectively. The optimum pH for the activity of different isozymes was between 4 and 6. The isoenzymes were determined to be thermally stable upto 40oC. The Km for gal I was 1.85mM,1.7mM for gal II and 1.19 for gal III.The Vmax for gal I, gal II aand gal III was found to be 0.52,0.70 and 0.38µmole/min respectively. 164 pp. Englisch.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Los radicales libres son subproductos de diferentes procesos fisiológicos y desempeñan un papel importante en las vías metabólicas, de señalización y de desarrollo. Los contaminantes del medio ambiente, el tabaquismo, las radiaciones UV y los alimentos también pueden inducir la formación de radicales libres o pro-oxidantes. La producción excesiva de radicales libres tiene un impacto adverso en los organismos vivos y puede causar un estrés oxidativo que provoca grandes daños celulares. El daño oxidativo mediado por los radicales libres desempeña un papel importante en la patogénesis del cáncer y en los trastornos neurodegenerativos, metabólicos, reproductivos y psicológicos. Los organismos vivos han desarrollado mecanismos de defensa eficaces para contrarrestar los efectos nocivos de los radicales libres mediante el empleo de diferentes antioxidantes. Este libro presenta los procesos vitales fundamentales que sustentan la vida, los tipos de radicales libres, su generación y su efecto sobre las biomoléculas y las estructuras celulares. Se analizan detalladamente los tipos de antioxidantes y los mecanismos utilizados para neutralizar los efectos nocivos de los oxidantes. Se examinan los metabolitos secundarios y fitoquímicos de origen vegetal con potencial antioxidante y terapéutico. Por último, este libro explica el papel del estrés oxidativo en la patogénesis de los trastornos en los seres humanos.…
